Many of my aircraft with digital servos get their best performance with a voltage in the range of 6-7 volts.
Now I know that the board cannot power them, I also thought I read somewhere the maximum voltage on the output side is like 5.5v.
So, this makes me think that if I just make a separate power buss for the servos, share the ground with the APM and just send the signal to the individual servo.
Will this work or am I asking to have problems? I hope to move to heli platform with one of my APM’s and they really need the extra power and speed.
Right now, on my plane, the input is powered by one source, the APM by the power module, and the servo side with another source, all of which are 5v. No power goes from receiver to APM inputs, only the signal but again the ground is shared.
