Frsky receiver not working with brushed motor
Don't know if anyone else has seen this. It doesn't make sense to me, maybe someone knows why. I dug out an old trainer plane of mine for a friend that is learning to fly. It has a brushed motor/brushed esc designed to handle lipos and I'm running with a small 2S lipo.
The old receiver was FM but I wanted to try my Frsky rx in it.
Well all channels worked except the esc/motor (ch3). I got proper servo movement but no response from the motor. Took me a long time as I figured it was the esc, then possibly the old brushed motor but swapping them out did nothing, no motor response.
Then went back to the old FM receiver and everything functioned.
Anyone know why? It seems crazy to me, the Rx should be giving the same signal to the esc, but maybe not ?

Make sure the FrSky reciever is not in "High Speed" mode.
The LED should flash slowly if you turn on the receiver without turning on the transmitter. If it flashes quickly then press the bind button for 3 seconds to change modes.
(This assumes you are using a D8 telemetry receiver)

I bet your brushed ESC doesn't like it. Look here for more info.

Old brushed ESC was probably made to match old FM receiver.
Just stay with old FM radio.
To fly with 2.4, change motor and ESC to modern brushless.
