May I borrow your expertise for help troubleshooting? I have a Kakute F7 Mini Combo with the Tekko 32 ESC. I have loaded Ardupilot 4.03. For trouble shooting purposes I also later loaded 4.0 and the latest bleeding edge release to the same result, so I am back to 4.03. My motor B will not budge. I have tried testing all 4 motors with Mission Planner and QGroundControl. Motors A, C, and D test perfectly on MP and QGC. Motor B does a tiny twitch like the other motors when I plug in the battery and I hear the typical armed sound (three beeps, pause, then two longer ones). But nothing else showing life after that.
The motors are Readytosky MT2204 2300KV Brushless Motor 2-3S. I have taken motor B off of the quad frame and replaced with 2 other motors (almost identical and that I know work). Those motors won’t budge either. So I put the original motor back on and twice using two gauges of wire (20 and 16 awg) re-soldered the motor back to the esc. I also tried changing the soldered wires around to no avail. I have even changed the included 8 wire esc to fc connecting cable to to no avail. Arggg!
I do not have a transmitter or receiver I am planning on using serial with a companion pi to take off and land.
Is there anything else I could test? Thank you
