Hello,
I have an M4 v2 (r1) and N4 combination that I want to use with an external ESC, which is a SimonK based 10 A 4 in 1 ESC. This in turn runs the motors for a QAV 250 sized frame with 5 inch propellers.
The main problem I'm having is an inconsistent PWM signal from the Autoquad. The ESC signal cables are connected to ports 5, 6, 7 and 8 on the N4 with a Quad X configuration, and initially I tried setting the arm PWM ~ 975, minimum to 1100 and maximum to 1800. The motors stop beeping when the Autoquad is armed, but the motors spin randomly when throttle is raised (either only one motor spins, or two spin, usually at a very high speed). Even through tweaking these values around, and/or changing the MOT_VALUE2_A1, A2 and SCAL parameters, there's no improvement. If I monitor the SERVO_OUTPUT data in QGroundControl and raise the throttle, the PWM values of the four motors are unequal and two motors jump to the range of 3000-4000 immediately, and two stay around 1000. I couldn't find any information about how exactly to fine tune the A1, A2 and SCAL parameters, so I was wondering if I could get some suggestions/pointers about what's going wrong and what I can do to fix it?
Thank you very much,
Sai
