Do not assume the app has remembered your previous selections.Tilt SensorThe Tilt Sensor is a built-in safety feature exclusive to the Foil Drive Fusion System (Gen 2.5). It is enabled from factory and is designed to automatically shut off the motor if your board tilts beyond a pre-set range. This feature helps prevent the motor from running when your board is upside down, off balance, or in an unsafe position.What Does the Tilt Sensor Do?The Tilt Sensor continuously monitors your board&#x2019;s&#xA0;pitch&#xA0;(forward and backward angle) and&#xA0;roll&#xA0;(side-to-side tilt). &#xA0;If your board goes beyond the programmed tilt range, the system will instantly cut power to the motor.To learn more about Tilt Sensor,&#xA0;<a href="https://help.foildrive.com/en-US/how-to-adjust-tilt-sensor-sensitivity-2531862" target="_blank" rel="noopener noreferrer">Click here.</a><h1 id="isPasted" style="line-height: 2; text-align: center;">Completing Setup</h1>Once you have selected your desired settings:<ol data-spread="false" start="1"><li style="font-size: 14px; line-height: 2;">Review the displayed system configuration.</li><li style="font-size: 14px; line-height: 2;">Confirm your settings.</li><li style="font-size: 14px; line-height: 2;">The app will write the selected settings to your Foil Drive system.</li><li style="font-size: 14px; line-height: 2;">Wait for the app to display Ready to Fly.</li><li style="font-size: 14px; line-height: 2;">Select Done to return to the home screen.</li></ol>Your Foil Drive system is now configured with the selected settings.<h2 style="line-height: 2; text-align: center;" id="connection-timeout">Connection Timeout</h2>For safety, the app will automatically disconnect if the setup process takes too long.If this happens:<ol data-spread="false" start="1"><li style="font-size: 14px; line-height: 2;">Reconnect to the system.</li><li style="font-size: 14px; line-height: 2;">Review your settings.</li><li style="font-size: 14px; line-height: 2;">Confirm the setup again.</li></ol><h1 id="isPasted" style="line-height: 2; text-align: center;">Troubleshooting Connection Issues</h1>If you are having difficulty connecting the Foil Drive App to your system, see our <a href="https://help.foildrive.com/en-US/connection-troubleshooting-293438" target="_blank" rel="noopener noreferrer">Connection Troubleshooting</a>&#xA0;guide for assistance.If you continue to have difficulty connecting, contact Foil Drive Support.

Foil Drive App Overview

Not sure which Power Mode is right for your Foil Drive setup? Learn how the different Power Modes work, how they affect motor performance and when to use each mode to get the best response for your riding.

Foil Drive systems have four adjustable Power Modes, each designed for different riders, riding conditions and levels of experience.The four Power Modes are:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Learn</li><li style="font-size: 14px; line-height: 2;">Low</li><li style="font-size: 14px; line-height: 2;">Medium</li><li style="font-size: 14px; line-height: 2;">High</li></ul>Each mode has its own default settings for power output, motor spool-up speed and latency.<h2 id="isPasted" style="line-height: 2; text-align: center;">Learn Mode</h2>Learn Mode is designed to make your first experience with Foil Drive as smooth, predictable and controlled as possible.It reduces the motor&apos;s spool-up speed, meaning the motor accelerates gradually even when full throttle is applied. This provides a smoother increase in thrust and helps prevent the sudden, jerky feeling that can occur when learning to control the throttle.Learn Mode also uses:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Reduced power output for a gentler level of thrust.</li><li style="font-size: 14px; line-height: 2;">Slower motor spool-up for smoother throttle response.</li><li style="font-size: 14px; line-height: 2;">Shorter latency so the motor cuts out quickly if communication between the controller and Foil Drive system is lost.</li></ul><img src="https://attachments.gorgias.help/uploads.gorgias.io/z8QbV2Pk1e6ogePy/Foil-Drive-App-Icon-Power-Mode-Learn-0e6438dc-d433-4340-bbd6-f8f50f211253.png" style="width: 117px;" class="fr-fic fr-fil fr-dii"> Learn Mode is recommended for first-time riders, children and anyone who is unfamiliar with Foil Drive. The combination of lower power, smoother acceleration and shorter latency makes Learn Mode a great way to become comfortable with the system before moving to higher power levels.<h2 id="isPasted" style="line-height: 2; text-align: center;">Low, Medium and High Power</h2>Low, Medium and High Power all provide progressively more power output:Low &#x2192; Medium &#x2192; High&#xA0;Unlike Learn Mode, these three modes use the same default latency and spool-up settings. The main difference between them is the available power output.<h3 style="line-height: 2;" id="low-power">Low Power</h3>Low Power provides a lower level of thrust and can be useful for:&#xA0;<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Lighter riders</li><li style="font-size: 14px; line-height: 2;">Larger or more efficient foils</li><li style="font-size: 14px; line-height: 2;">Larger boards</li><li style="font-size: 14px; line-height: 2;">Easier riding conditions</li><li style="font-size: 14px; line-height: 2;">Riders wanting to conserve battery</li></ul><h3 id="isPasted" style="line-height: 2;">Medium Power</h3>Medium Power provides a balance between power and battery efficiency.&#xA0;It can be a good choice when conditions and equipment don&apos;t require the maximum available power, while still providing more thrust than Low Power.<h3 style="line-height: 2;" id="high-power">High Power</h3>High Power provides the highest level of thrust and is useful when more power is required, such as for:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Heavier riders</li><li style="font-size: 14px; line-height: 2;">Smaller boards</li><li style="font-size: 14px; line-height: 2;">Smaller foils</li><li style="font-size: 14px; line-height: 2;">Higher-performance setups</li><li style="font-size: 14px; line-height: 2;">More challenging conditions</li><li style="font-size: 14px; line-height: 2;">Riders who require maximum assistance during take-off</li></ul><h2 id="isPasted" style="line-height: 2; text-align: center;">Choosing the Right Power Mode</h2>There is no single Power Mode that is best for every rider.The ideal setting depends on factors such as:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Rider weight</li><li style="font-size: 14px; line-height: 2;">Board size and volume</li><li style="font-size: 14px; line-height: 2;">Foil size</li><li style="font-size: 14px; line-height: 2;">Riding conditions</li><li style="font-size: 14px; line-height: 2;">Take-off technique</li><li style="font-size: 14px; line-height: 2;">Desired battery runtime</li></ul>For example, a lighter rider using a larger foil may not need High Power. Choosing Low or Medium Power can provide enough thrust while helping extend battery runtime.A heavier rider using a small board and small foil may require High Power to achieve the thrust needed for take-off.<h3 style="line-height: 2; text-align: center;" id="lower-power-can-extend-battery-runtime">Lower Power Can Extend Battery Runtime</h3>Using a lower Power Mode can help extend your battery runtime because the system is capable of producing less thrust.If conditions are easier than usual, or you are using a larger foil, consider reducing the Power Mode rather than using more throttle than necessary.Higher power is not always better. Choose the lowest Power Mode that provides the performance you need for your setup and conditions.<h2 id="isPasted" style="line-height: 2; text-align: center;">Changing Your Power Mode</h2>Important: After updating your Foil Drive system, app, or V3 Controller, re-calibrate your V3 Controller triggers before riding.<h1 style="line-height: 2; text-align: center;" id="connect-your-foil-drive-to-the-app">Connect Your Foil Drive to the App</h1><h3 style="line-height: 2;" id="1-select-your-system">1.

Connection Troubleshooting

Want an extra burst of power when you need it? Learn how Boost Mode works on your Foil Drive V2 Controller, when to use it and how it can help with take-offs, acceleration and challenging conditions.

Boost Mode&#xA0;allows your Foil Drive system to temporarily provide additional power above the normal 100% throttle output during take-off.Boost Mode is available on&#xA0;Gen2 and Gen2.5 Foil Drive systems and can be adjusted through the&#xA0;Foil Drive App.Depending on your Foil Drive system and battery combination, Boost can be adjusted from&#xA0;1% up to 24%, or switched&#xA0;OFF.<h2 style="line-height: 2; text-align: center;" id="what-is-boost-mode">What is Boost Mode?</h2>Boost Mode provides&#xA0;additional power on top of full throttle to help generate extra thrust during take-off.For example, if Boost is set to&#xA0;20%, the system can provide up to&#xA0;120% of normal full-throttle power while Boost is active.Boost is particularly useful when you need extra thrust to get up and riding, such as with:<ul><li id="isPasted" style="font-size: 14px; line-height: 2;">Heavier riders</li><li style="font-size: 14px; line-height: 2;">Smaller boards</li><li style="font-size: 14px; line-height: 2;">Smaller or higher-performance foils</li><li style="font-size: 14px; line-height: 2;">Flat-water conditions</li><li style="font-size: 14px; line-height: 2;">Low-wind conditions</li><li style="font-size: 14px; line-height: 2;">Low or weak surf</li><li style="font-size: 14px; line-height: 2;">Situations where additional take-off thrust is helpful</li></ul>Boost is not required for normal riding. It is an optional feature that provides additional thrust when you need it.<h2 id="isPasted" style="line-height: 2; text-align: center;">How Much Boost Can I Use?</h2>The maximum Boost available depends on the&#xA0;Foil Drive system and battery combination.Some combinations allow up to&#xA0;24% additional Boost, providing up to&#xA0;124% of normal full-throttle power.The Foil Drive App will only allow Boost settings that are supported by your connected system and battery.<h3 style="line-height: 2; text-align: center;" id="boost-duration">Boost Duration</h3>The Foil Drive App also allows you to adjust how long Boost is available during a take-off.Depending on the system, Boost can be programmed for&#xA0;up to 22 seconds.You can choose a shorter Boost period if you only want additional power for the initial part of your take-off.<h2 id="isPasted" style="line-height: 2; text-align: center;">Factory Boost Setting</h2>Boost is programmed with a default setting from the factory.The default setting may vary depending on the&#xA0;system, battery and software version.Always check the Boost setting displayed in the Foil Drive App rather than assuming a particular Boost percentage or duration.<h2 style="line-height: 2; text-align: center;" id="how-do-i-adjust-boost-mode">How Do I Adjust Boost Mode?</h2>Boost Mode is adjusted during the&#xA0;Foil Drive system programming process in the Foil Drive App.<ol data-spread="false" start="1"><li style="font-size: 14px; line-height: 2;">Connect your Foil Drive system to the Foil Drive App.</li><li style="font-size: 14px; line-height: 2;">Select Set Up / Reprogram Foil Drive.</li><li style="font-size: 14px; line-height: 2;">Select your desired Power Mode.</li><li style="font-size: 14px; line-height: 2;">Adjust the Boost Mode setting.</li><li style="font-size: 14px; line-height: 2;">Select your desired Boost percentage, or switch Boost OFF.</li><li style="font-size: 14px; line-height: 2;">Adjust the Boost duration if this option is available for your system.</li><li style="font-size: 14px; line-height: 2;">Review all settings.</li></ol>Select Save and wait for the app to display&#xA0;Ready to Fly. Always review your Boost setting before saving your Foil Drive configuration. Do not assume your previous Boost setting has been retained when reprogramming the system.<h2 id="isPasted" style="line-height: 2; text-align: center;">How Do I Activate Boost?</h2>Boost is automatically available when the system detects the required throttle position.To activate Boost during take-off:<ol data-spread="false" start="1"><li style="font-size: 14px; line-height: 2;">Pull the throttle trigger past approximately&#xA0;95% throttle.</li><li style="font-size: 14px; line-height: 2;">Boost will activate and provide the additional programmed power.</li><li style="font-size: 14px; line-height: 2;">Continue using the throttle normally during the Boost period.</li></ol>If you release the throttle during the Boost period, Boost will deactivate and the system will return to normal throttle operation.To activate Boost again, the system must first meet its reactivation conditions before Boost can be triggered again.<h3 id="isPasted" style="line-height: 2; text-align: center;">Boost Re-Activation</h3>Boost cannot be repeatedly activated without allowing the system time to reduce heat and load.After Boost has been used, the throttle must be reduced below the required threshold for the required period before Boost can be activated again.These limits are built into the system to help manage heat and protect the Foil Drive components. Do not attempt to bypass or modify these protections.<h2 id="isPasted" style="line-height: 2; text-align: center;">Boost and Battery Runtime</h2>Using Boost increases the power drawn from the battery.Higher Boost settings can therefore:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Reduce overall battery runtime</li><li style="font-size: 14px; line-height: 2;">Increase battery load</li><li style="font-size: 14px; line-height: 2;">Increase battery degradation over time</li></ul>You do not need to use the maximum available Boost. For the best balance between performance and battery runtime, use only as much Boost as you need.<h2 style="line-height: 2; text-align: center;" id="boost-at-lower-battery-charge">Boost at Lower Battery Charge</h2>As the battery charge decreases, battery voltage also decreases.Under high loads, such as maximum throttle with Boost active, you may notice voltage sag. This means the maximum thrust available later in the battery&apos;s discharge may be slightly lower than when the battery was fully charged.This is normal battery behaviour.<h2 id="isPasted" style="line-height: 2; text-align: center;">Choosing the Right Boost Setting</h2>More Boost is not necessarily better.Consider starting with a lower Boost setting and increasing it only if you need additional take-off thrust.For example:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Larger foil / lighter rider: Less Boost may be required.</li><li style="font-size: 14px; line-height: 2;">Smaller foil / heavier rider: More Boost may be useful.</li><li style="font-size: 14px; line-height: 2;">Easy conditions: Lower Boost can help conserve battery.</li><li style="font-size: 14px; line-height: 2;">Difficult take-off conditions: Higher Boost may provide the additional thrust needed.</li></ul>Boost is an optional performance feature. Use the lowest setting that provides the take-off performance you need.<h2 id="isPasted" style="line-height: 2; text-align: center;">Key Points</h2><ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Boost provides&#xA0;additional power above normal 100% throttle.</li><li style="font-size: 14px; line-height: 2;">Boost is adjustable through the&#xA0;Foil Drive App.</li><li style="font-size: 14px; line-height: 2;">Maximum Boost depends on your&#xA0;system and battery combination.</li><li style="font-size: 14px; line-height: 2;">Boost duration can also be adjusted on supported systems.</li><li style="font-size: 14px; line-height: 2;">Boost is primarily intended to provide additional thrust during&#xA0;take-off.</li><li style="font-size: 14px; line-height: 2;">Repeated Boost activation is restricted to help manage heat and component load.</li><li style="font-size: 14px; line-height: 2;">Higher Boost settings use more battery power and may increase battery degradation.</li><li style="font-size: 14px; line-height: 2;">Boost is optional and can be switched&#xA0;OFF.</li></ul>&#xA0;

Understanding Boost Mode

Want to understand the delay between your controller input and motor response? Learn what latency is, what can affect it and how it impacts the responsiveness of your Foil Drive system.

Latency&#xA0;is an advanced setting that controls how long the Foil Drive motor continues running after the controller loses communication with the Foil Drive system.Latency can be adjusted through the Foil Drive App on compatible Gen2 and Gen2.5 systems.<h2 style="line-height: 2; text-align: center;" id="what-is-latency">What is Latency?</h2>Latency is the time between the Foil Drive system losing communication with the controller and the motor automatically cutting out.For example, if you fall into the water and the controller moves out of range, the Foil Drive system will detect the lost connection and stop the motor after the programmed latency period.Latency does NOT affect the motor cut-off when you release the throttle trigger. Releasing the throttle causes the motor to stop immediately, regardless of the latency setting.<h2 id="isPasted" style="line-height: 2; text-align: center;">Low vs High Latency</h2><h3 style="line-height: 2;" id="low-latency">Low Latency</h3>Low Latency provides a faster motor cut-off when communication with the controller is lost.A low latency setting can be around 100 milliseconds, meaning the motor will cut out very quickly after the connection is lost.Low Latency is recommended for:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">New riders</li><li style="font-size: 14px; line-height: 2;">Children learning to use Foil Drive</li><li style="font-size: 14px; line-height: 2;">Riders learning a new setup</li><li style="font-size: 14px; line-height: 2;">Riders who prioritise the quickest possible motor cut-off</li></ul>A shorter latency provides an additional safety benefit because the motor will stop sooner after a loss of communication.<h3 id="isPasted" style="line-height: 2;">High Latency</h3>High Latency allows a longer period before the motor cuts out after communication with the controller is lost.This can be beneficial when the wireless signal is more likely to be temporarily interrupted without the rider actually falling off.For example, some low-volume boards or full-carbon boards can make maintaining a consistent wireless connection more difficult. A higher latency setting can help prevent unwanted motor cut-outs caused by brief signal interruptions.<h2 style="line-height: 2; text-align: center;" id="when-should-i-use-high-latency">When Should I Use High Latency?</h2>High Latency should only be considered once you are comfortable and competent with your Foil Drive system and setup.It may be useful if you are experiencing unwanted motor cut-outs caused by brief communication interruptions, particularly with:<ul><li id="isPasted" style="font-size: 14px; line-height: 2;">Low-volume boards</li><li style="font-size: 14px; line-height: 2;">Full-carbon boards</li><li style="font-size: 14px; line-height: 2;">Setups where the controller is frequently obstructed from the Foil Drive antenna</li><li style="font-size: 14px; line-height: 2;">Conditions where the controller temporarily moves out of the ideal signal range</li></ul>High Latency delays the automatic motor shut-off after a loss of communication. This means the motor can continue running for longer if you fall or lose connection. For this reason, higher latency increases the potential safety risk and should only be used by experienced, competent riders.Before increasing latency, check that your antenna, controller and Foil Drive installation are correctly positioned and that there are no other factors causing poor signal connection.<h2 style="line-height: 2; text-align: center;" id="choosing-the-right-latency">Choosing the Right Latency</h2>As a general rule:Lower latency = quicker automatic shut-off and increased safety marginHigher latency = greater tolerance of brief signal interruptions, but a longer motor run-on period if communication is lostFor most riders, the lowest latency that provides reliable operation is the best choice.If you are experiencing unexpected motor cut-outs, do not immediately increase latency. First investigate the cause of the communication loss.<h2 id="isPasted" style="line-height: 2; text-align: center;">Adjusting Latency</h2>Latency can be adjusted in Advanced Settings through the Foil Drive App during the system programming process.Always check your Latency setting before riding. Make sure the setting is appropriate for your experience level, board construction and riding conditions.

Understanding Latency

Wondering how the Tilt Sensor works in your Foil Drive system? Learn what the Tilt Sensor detects, when it activates and how it helps provide an important layer of safety during your session.

The Tilt Sensor is a safety feature available on Gen2.5 Fusion systems.When enabled, the Tilt Sensor monitors the orientation of the Foil Drive unit and automatically stops the motor if the unit moves outside the programmed Pitch or Roll limits.The Tilt Sensor can be:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Turned ON or OFF</li><li style="font-size: 14px; line-height: 2;">Adjusted using the Foil Drive Controller</li><li style="font-size: 14px; line-height: 2;">Individually programmed for Pitch and Roll using the Foil Drive App</li></ul><h2 id="isPasted" style="line-height: 2; text-align: center;">How Does the Tilt Sensor Work?</h2>The Tilt Sensor uses an internal sensor to monitor the orientation of the Foil Drive unit.It monitors two directions:<img src="https://attachments.gorgias.help/z8QbV2Pk1e6ogePy/hc/g5KDM28bvmx9aByw/2026073005-b497aa72-5c1c-429b-a3a1-bf3bd39e00eb-roll-pitch%20advanced.jpeg" style="width: 227px;" class="fr-fic fr-fir fr-dii"><ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Pitch &#x2013; forward and backward tilt</li><li style="font-size: 14px; line-height: 2;">Roll &#x2013; side-to-side tilt</li></ul>If the unit moves beyond the programmed limit in either direction, the system will automatically stop the motor.For example, if the Tilt Sensor is set to 30&#xB0; Pitch and 30&#xB0; Roll, the motor will stop if the unit exceeds the programmed limit in any of these directions.The Tilt Sensor is a safety feature designed to automatically stop the motor if the board or Foil Drive unit moves outside the programmed orientation range.<h2 id="isPasted" style="line-height: 2; text-align: center;">Factory Default Setting</h2>The Tilt Sensor is enabled as standard on Gen2.5 Fusion systems.The default setting is:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Pitch Forward: 30&#xB0;</li><li style="font-size: 14px; line-height: 2;">Pitch Backward: 30&#xB0;</li><li style="font-size: 14px; line-height: 2;">Roll Right: 30&#xB0;</li><li style="font-size: 14px; line-height: 2;">Roll Left: 30&#xB0;</li></ul>This provides a 30&#xB0; limit in each direction.<h2 style="line-height: 2; text-align: center;" id="why-does-my-fusion-say-lock">Why Does My Fusion Say &quot;LOCK&quot;?</h2>When the Tilt Sensor is enabled, the Fusion system must be in an acceptable orientation before the motor can run.This means the system may display LOCK when the board is:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Upside down</li><li style="font-size: 14px; line-height: 2;">Sitting at an excessive angle</li><li style="font-size: 14px; line-height: 2;">Outside the programmed Pitch or Roll limits</li></ul>This is normal operation.<h3 id="isPasted" style="line-height: 2; text-align: center;">Preparing Your Gen2.5 for Riding</h3>When preparing your Foil Drive:<ol data-spread="false" start="1"><li style="font-size: 14px; line-height: 2;">Assemble the Foil Drive and board normally.</li><li style="font-size: 14px; line-height: 2;">Turn the board the correct way up.</li><li style="font-size: 14px; line-height: 2;">Position the board so it is sitting level, for example on the front foil and tail.</li><li style="font-size: 14px; line-height: 2;">Turn on the controller.</li><li style="font-size: 14px; line-height: 2;">Unlock the controller if required.</li><li style="font-size: 14px; line-height: 2;">Allow the unit to recognise that it is within the programmed tilt range.</li><li style="font-size: 14px; line-height: 2;">Confirm that the LOCK indication has cleared.</li><li style="font-size: 14px; line-height: 2;">Test the throttle only once the system is ready to operate.</li></ol>Warning:&#xA0;Do not test the motor while the board or unit is upside down or in an unsafe position.<h2 id="isPasted" style="line-height: 2; text-align: center;">What Happens if the Tilt Limit Is Exceeded?</h2>If the motor is running and the unit moves outside the programmed Pitch or Roll range, the Tilt Sensor will automatically stop the motor.Once the unit returns within the programmed range, the motor will not automatically restart.To restart the motor:<ol data-spread="false" start="1"><li style="font-size: 14px; line-height: 2;">Return the Fusion unit to within the programmed tilt range.</li><li style="font-size: 14px; line-height: 2;">Release the throttle completely.</li><li style="font-size: 14px; line-height: 2;">Return the throttle to 0%.</li><li style="font-size: 14px; line-height: 2;">The system can then be started normally.</li></ol>You must release the throttle and return it to zero before the motor can be restarted after a Tilt Sensor cut-off.This prevents the motor from automatically restarting while the unit is still outside its safe operating orientation.<h2 style="line-height: 2; text-align: center;" id="turning-the-tilt-sensor-on-or-off">Turning the Tilt Sensor ON or OFF</h2>The Tilt Sensor can be switched ON or OFF through Menu 7 &#x2013; Tilt Sensor on the Foil Drive Controller.To change the setting:<ol data-spread="false" start="1"><li style="font-size: 14px; line-height: 2;">Enter the controller menu.</li><li style="font-size: 14px; line-height: 2;">Navigate to Menu 7 &#x2013; Tilt Sensor.</li><li style="font-size: 14px; line-height: 2;">Select ON or OFF.</li><li style="font-size: 14px; line-height: 2;">Confirm the selection.</li><li style="font-size: 14px; line-height: 2;">Exit the menu.</li></ol>The Tilt Sensor can also be switched ON or OFF through the Foil Drive App or on the V3 Controller.The Tilt Sensor is a safety feature. We recommend keeping it enabled unless you have a specific reason to disable it.<h2 id="isPasted" style="line-height: 2; text-align: center;">Adjusting Pitch and Roll</h2>The Foil Drive App allows you to set the Pitch and Roll limits independently.This allows you to customise the Tilt Sensor to suit your riding style, experience level and equipment.For example, a rider learning to e-foil may choose a tighter Roll limit so the motor stops if the board is tilted significantly to one side.An experienced rider may prefer a wider range to allow for more aggressive riding, steep waves or sharper turns without triggering the Tilt Sensor.<h3 id="isPasted" style="line-height: 2;">Example Settings</h3>Beginner rider:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Lower Roll limit for a more restrictive safety range</li><li style="font-size: 14px; line-height: 2;">Moderate Pitch limit</li></ul>Experienced rider:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Wider Pitch and Roll limits</li><li style="font-size: 14px; line-height: 2;">Greater freedom for aggressive turns and steeper riding</li></ul>There is no single setting that is appropriate for every rider.Only increase the Tilt Sensor limits if you understand the effect this has on the safety function. Wider limits allow greater board movement before the motor automatically stops.<h2 id="isPasted" style="line-height: 2; text-align: center;">When Should I Adjust the Tilt Sensor?</h2>The factory 30&#xB0; Pitch and Roll setting is suitable for many riders and is a good starting point.You may want to adjust the settings if:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">You are learning and want a more restrictive safety range.</li><li style="font-size: 14px; line-height: 2;">You are experiencing unwanted motor cut-outs during normal riding.</li><li style="font-size: 14px; line-height: 2;">You regularly ride steep waves.</li><li style="font-size: 14px; line-height: 2;">You use aggressive turns or a large angle of roll.</li><li style="font-size: 14px; line-height: 2;">Your riding style requires a wider range of movement.</li></ul>If the Tilt Sensor is activating unexpectedly, consider whether the programmed limits are appropriate before disabling the feature completely.<h2 id="isPasted" style="line-height: 2; text-align: center;">Important Safety Information</h2>The Tilt Sensor is designed to help stop the motor when the Foil Drive unit moves outside the programmed orientation range.However, it should not be relied upon as the only safety feature. Always follow normal Foil Drive safety procedures and ensure the throttle is released whenever you are not intentionally operating the motor.Never deliberately test the Tilt Sensor while holding or handling a running propeller. The demonstration of this feature should only be performed using appropriate safety precautions.<h2 id="isPasted" style="line-height: 2; text-align: center;">Quick Reference</h2><table style="margin-right: calc(3%); width: 97%;"><thead><tr><th style="width: 34.8873%;">Feature</th><th style="width: 64.9135%;">Description</th></tr></thead><tbody><tr><td style="width: 34.8873%;">Tilt Sensor</td><td style="width: 64.9135%;">Safety feature that monitors Fusion orientation</td></tr><tr><td style="width: 34.8873%;">Pitch</td><td style="width: 64.9135%;">Forward and backward tilt</td></tr><tr><td style="width: 34.8873%;">Roll</td><td style="width: 64.9135%;">Side-to-side tilt</td></tr><tr><td style="width: 34.8873%;">Factory Setting</td><td style="width: 64.9135%;">30&#xB0; Pitch and 30&#xB0; Roll</td></tr><tr><td style="width: 34.8873%;">Motor Cut-Off</td><td style="width: 64.9135%;">Activates when the programmed limit is exceeded</td></tr><tr><td style="width: 34.8873%;">Restart After Cut-Off</td><td style="width: 64.9135%;">Return to range and release throttle to 0%</td></tr><tr><td style="width: 34.8873%;">Controller Menu</td><td style="width: 64.9135%;">Menu 7 &#x2013; Tilt Sensor</td></tr><tr><td style="width: 34.8873%;">App</td><td style="width: 64.9135%;">Turn Tilt Sensor ON/OFF and adjust Pitch/Roll individually</td></tr></tbody></table>

Understanding the Tilt Sensor

Not sure what your Foil Drive Activity and Inactivity Alarms mean? Learn how these alarms work, when they activate and what they indicate to help you understand your system’s status and stay aware during your session.

Foil Drive systems have two motor activity features designed to help you confirm that your system is active and remind you when the battery has been left connected:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Start-Up Activity Alarm</li><li style="font-size: 14px; line-height: 2;">Inactivity Alarm</li></ul>Both features use a brief oscillation of the motor to create an audible sound.These features are reminders and indicators only. Always remove the battery immediately after use.<h2 id="isPasted" style="line-height: 2; text-align: center;">Start-Up Activity Alarm</h2>The Start-Up Activity Alarm confirms that your Foil Drive system is active when the battery is connected.When the battery is connected, the motor will deliberately pulse back and forth, creating an audible sound.This feature:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Activates automatically when the system starts up.</li><li style="font-size: 14px; line-height: 2;">Is ON by default.</li><li style="font-size: 14px; line-height: 2;">Cannot be disabled.</li></ul>The start-up activity confirms that the system has powered up and is active.Important: Always make sure the propeller is clear and cannot cause injury before connecting the battery.<h3 id="isPasted" style="line-height: 2; text-align: center;">What if the Motor Does Something Different?</h3>The start-up activity should consist of the motor briefly pulsing back and forth and producing an audible sound.If your motor behaves differently from this, the behaviour is not typical and should be investigated.See Motor System Troubleshooting and Repair for further assistance.<h2 style="line-height: 2; text-align: center;" id="inactivity-alarm">Inactivity Alarm</h2>The Inactivity Alarm is a reminder that your Foil Drive system is still powered on with the battery connected.If the controller has remained at 0% throttle for the programmed period, the motor will pulse back and forth to create an audible alarm.The factory default timer is: 15 minutesThis timer can be adjusted or disabled through the Advanced Settings in the Foil Drive App.<h2 style="line-height: 2; text-align: center;" id="how-does-the-inactivity-alarm-work">How Does the Inactivity Alarm Work?</h2>Once the Foil Drive system is powered on, the inactivity timer monitors throttle activity.If there is no throttle activity for the programmed period, the motor will pulse back and forth and produce an audible sound.The timer will restart when:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">The throttle is engaged and subsequently returned to 0%, or</li><li style="font-size: 14px; line-height: 2;">The controller is turned off.</li></ul>This allows the alarm to act as a reminder if the system has been left powered on between rides.<h2 id="isPasted" style="line-height: 2; text-align: center;">Adjusting the Inactivity Alarm</h2>The Inactivity Alarm can be adjusted through the Foil Drive App.<ol data-spread="false" start="1"><li style="font-size: 14px; line-height: 2;">Connect your Foil Drive system to the app.</li><li style="font-size: 14px; line-height: 2;">Enter the system programming/settings screen.</li><li style="font-size: 14px; line-height: 2;">Open Advanced Settings.</li><li style="font-size: 14px; line-height: 2;">Locate Inactivity Reminder.</li><li style="font-size: 14px; line-height: 2;">Select your desired timer.</li><li style="font-size: 14px; line-height: 2;">Save the settings.</li></ol>Setting the timer to 0 disables the Inactivity Alarm.We do not recommend disabling the Inactivity Alarm. It provides an additional reminder to disconnect the battery after use.<h2 id="isPasted" style="line-height: 2; text-align: center;">The Inactivity Alarm Is Not a Safety System</h2>The Inactivity Alarm is simply a reminder.It does not automatically disconnect or shut down the battery, and it should never be relied upon to prevent battery discharge or other risks associated with leaving a battery connected.The rider is responsible for removing the battery after every use.Always remove the battery immediately after riding and never store your battery inside the Foil Drive unit.<h2 id="isPasted" style="line-height: 2; text-align: center;">Quick Reference</h2><table><thead><tr><th><div style="text-align: center;">Feature</div></th><th><div style="text-align: center;">Start-Up Activity Alarm</div></th><th><div style="text-align: center;">Inactivity Alarm</div></th></tr></thead><tbody><tr><td><div style="text-align: center;">Purpose</div></td><td><div style="text-align: center;">Confirms the system is active</div></td><td><div style="text-align: center;">Reminds you the battery is still connected</div></td></tr><tr><td><div style="text-align: center;">When it activates</div></td><td><div style="text-align: center;">When the battery is connected</div></td><td><div style="text-align: center;">After the programmed period without throttle activity</div></td></tr><tr><td><div style="text-align: center;">Factory setting</div></td><td><div style="text-align: center;">ON</div></td><td><div style="text-align: center;">15 minutes</div></td></tr><tr><td><div style="text-align: center;">Can it be disabled?</div></td><td><div style="text-align: center;">No</div></td><td><div style="text-align: center;">Yes, but not recommended</div></td></tr><tr><td><div style="text-align: center;">Motor behaviour</div></td><td><div style="text-align: center;">Brief pulsing/oscillation</div></td><td><div style="text-align: center;">Pulsing/oscillation with audible alarm</div></td></tr><tr><td><div style="text-align: center;">Battery removal required?</div></td><td><div style="text-align: center;">Yes</div></td><td><div style="text-align: center;">Yes</div></td></tr></tbody></table> ImportantAlways follow these battery handling practices:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Remove the battery immediately after use.</li><li style="font-size: 14px; line-height: 2;">Never store the battery inside the Foil Drive unit.</li><li style="font-size: 14px; line-height: 2;">Do not rely on the Inactivity Alarm as a substitute for disconnecting the battery.</li><li style="font-size: 14px; line-height: 2;">Always ensure the propeller is clear before connecting the battery.</li></ul>If your motor shows behaviour other than the normal start-up activity described above, stop using the system and follow the&#xA0;<a href="https://help.foildrive.com/en-US/articles/motor-system-100367" target="_blank" rel="noopener noreferrer">Motor System Troubleshooting Guide</a>&#xA0;or contact Foil Drive Support for further assistance.

How to Program Your Foil Drive

Learn how to use the Power ON/OFF control in the APP to prevent unnecessary battery drain while the battery remains connected to your Foil Drive system. This feature is ideal for trench board users preparing their system ahead of a session.

Gen2.5 batteries feature a Power ON/OFF control that allows you to turn the battery output OFF while the battery remains connected to the Foil Drive system.This feature is particularly useful for trench board users who want to prepare their system ahead of time, such as setting up the night before a session, without unnecessarily draining the battery.Important: This feature is not available on Gen2 Max and SLIM batteries.<h2 style="text-align: center; line-height: 2;" id="how-it-works">How It Works</h2>When the battery output is turned OFF through the Foil Drive App, the battery can remain physically connected to the system without supplying power.This allows you to prepare your Foil Drive system in advance while helping preserve battery charge until you&apos;re ready to ride.<h3 style="text-align: center; line-height: 2;" id="using-the-power-off-function">Using the Power OFF Function</h3><ol data-spread="false" start="1"><li style="font-size: 14px; line-height: 2;">Install the Fusion Battery into your Foil Drive system.</li><li style="font-size: 14px; line-height: 2;">Open the Foil Drive App and connect to your system.</li><li style="font-size: 14px; line-height: 2;">Select Power OFF to turn the battery output off.</li><li style="font-size: 14px; line-height: 2;">Leave the battery connected while completing your setup.</li><li style="font-size: 14px; line-height: 2;">When you&apos;re ready to ride, turn the battery ON again through the App.</li><li style="font-size: 14px; line-height: 2;">Confirm the system is operating correctly before entering the water.</li></ol><h2 id="isPasted" style="text-align: center; line-height: 2;">Important Battery Safety</h2>The Power OFF function is the only circumstance where the Gen2.5 Battery should be left connected to the system when it is not in use.Never leave the battery connected and switched ON when the Foil Drive system is not being used.Leaving the battery connected and ON can cause excessive battery drain and may permanently damage the battery.If your Foil Drive system will not be used for an extended period, disconnect the battery from the system and follow the recommended battery storage and care procedures.<h3 style="text-align: center; line-height: 2;" id="example-preparing-a-trench-board-the-night-before">Example: Preparing a Trench Board the Night Before</h3>If you&apos;re preparing your trench board the night before a session:Night before<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Install the Fusion Battery.</li><li style="font-size: 14px; line-height: 2;">Connect the battery to the system.</li><li style="font-size: 14px; line-height: 2;">Open the Foil Drive App.</li><li style="font-size: 14px; line-height: 2;">Select Power OFF.</li><li style="font-size: 14px; line-height: 2;">Complete your board setup and leave the battery connected.</li></ul>Before your session<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">Open the Foil Drive App.</li><li style="font-size: 14px; line-height: 2;">Turn the battery ON.</li><li style="font-size: 14px; line-height: 2;">Check that the system is functioning correctly.</li><li style="font-size: 14px; line-height: 2;">You&apos;re ready to ride.</li></ul>Remember: Battery connected +&#xA0;Power OFF = OK for pre-session setup.
