My idea is to fit a small plane (Volantex / Eachine) with Arduplane. Have this breadboard with components for testing. Clockwise beginning with CC3D Mini (Arduplane 4.5.7) in lower right corner, the 2 servos (AIL, ELE) a 6A Turnigy plush with motor, ELRS receiver and BL slave for communication to my computer.
Several attempt to get the BEC and Motor working, but no luck. Changed the BEC, the motor, the FC and receiver, used different versions of Arduplane and calibrated a lot.
Then I connected my oscilloscope on the connector BEC - FC (signal to ground) and suddenly it worked like a charm. So I added a 1 M resistor as a pull down and that seems to solve my problem.
But what is happening here, I don’t understand?
