Hi. Just a quick question. I am designing a glider which will detect thermals (via vario) and loiter untill a certain height is reached, move on and do the same.
My question main question is, how can I power my 4 channel reciever and still retain all 4 channels? Ie have 3 servos, throttle and power from an external reciever battery.
any ideas would be very handy, cheers!
This is taken care of by the ESC usually, (throttle channel backfeeds 5V to the controlling receiver). But if your ESC doesn't have a BEC, (or despite your throttle reference, you don't have an ESC) you could just use a servo Y-Cable to feed power into the system. As long as you get your pinouts correct, putting ground and 5 or 6V in on the appropriate wires in the servo cable will work without sacrificing the channel.
Thanks Jay, The throttle controls the flaps and camber/reflex on this autonomous DLG and the apm will be powered by the rx battery as well. So I will try the Splitter cable you suggest to power rx and apm directly from the NIMH battery,
Many thanks Chris
