Hi guys,just a quick question.I have just finished the E Flight sabre and would like to run a seperate receiver battery pack & on/off switch to run the servos only,allowing the main lipo 4s to run the motor.Do I need todo anything differently?? and will the lipo pack still power up the reciever as it does now? or do you disconnect one of the wires from the speed controller to the reciever??
Any help much appreciated.

Regards OMRA

You'll need to disable the the BEC in the ESC. Pulling the red wire on the ESC plug will do that. Normally I just use a 3inch extension with the red wire cut. Other wise you flight pack would be installed as usual. First turn on the flight pack then pull in your LiPo.

Thankyou mike.So just pull out the red wire of the speed controller yeah,will I still need to disable the BEC?

My Feedback: (1)

That's all you need to do. The main danger was that the BEC would fight (or charge) the on board RX battery (which you don't want). Removing the red wire connection effectively disables the BEC function of the ESC as far as the RX is concerned. No need to change anything else on your ESC.
