Learn how to pair or re-pair your V2 Controller to your Foil Drive system, including the correct menu sequence, pairing procedure and troubleshooting steps if pairing is unsuccessful.

The V2 Controller is paired to your Foil Drive system during normal setup. You may need to re-pair the controller if you receive a replacement controller, the controller has lost its connection to the system, or Foil Drive Support has asked you to re-pair it.For instructional video, see:&#xA0;<a href="https://www.youtube.com/watch?v=Qtj60Nh0Q28" target="_blank" rel="noopener noreferrer">V2 Controller Pairing Guide</a><h2 style="line-height: 2; text-align: center;" id="re-pairing-instructions">Re-Pairing Instructions</h2><h3 style="line-height: 2;" id="1-turn-on-the-controller">1.

Detailed article on how to re-calibrate triggers on your Foil Drive™ Wireless Controller.

The throttle calibration on your V2 Controller ensures the controller correctly recognises the minimum and maximum positions of both triggers.Calibration is rarely required, but it may be necessary if the throttle readings are incorrect or the controller is not correctly detecting the full range of trigger movement.For instructional video, see:&#xA0;<a href="https://www.youtube.com/watch?v=glVDpMg5Qd0" target="_blank" rel="noopener noreferrer">Recalibrating the Controller Triggers&#xA0;</a><h2 style="line-height: 2; text-align: center;" id="when-to-recalibrate">When to Recalibrate</h2>You may need to recalibrate the controller if:<ul data-spread="false"><li style="font-size: 14px; line-height: 2;">The throttle does not correctly reach 0% or 100%.</li><li style="font-size: 14px; line-height: 2;">Trigger positions are being detected incorrectly.</li><li style="font-size: 14px; line-height: 2;">A trigger has been replaced.</li><li style="font-size: 14px; line-height: 2;">A trigger spring has been replaced.</li><li style="font-size: 14px; line-height: 2;">Foil Drive Support has asked you to recalibrate the controller.</li></ul><h2 style="line-height: 2; text-align: center;" id="recalibration-instructions">Recalibration Instructions</h2><h3 style="line-height: 2;" id="1-turn-on-the-controller">1.
