When I tested the power system I cannot get one of the speed controllers to work.
Initially I just plugged them both in to test and only one motor worked.
After a process of elimination of trying different components I got both EDF units to work using another 40 amp 4S esc from another
project so both EDF units work fine. I then tested the model's speed controllers individually and one works fine, individually running
either EDF unit and another motor on my test bench. The other one refuses to work. It makes all the right beeps. I have read the manual
and calibrated it to throttle input, changed timing and then reset to default settings but it will not spin up a motor.
After seeming to arm successfully, when throttle is applied the motor makes a very faint noise like it is trying to spin then after
a few seconds the esc begins to emit its continuous error beeping until throttle is returned to zero. And so on.
I am pretty sure it is defective but I am open to suggestions.
