I work on new version of my lovely HEXA with Turnigy Multistar 690kV (22 pole) motors on LiPo4s.
I meet a big problems with this motors and some ESC with SimonK FW.
With timings 18 degree (default) motors are so hot (it is possible to woter bowlin) and power is consumed immediately that it is not possible fly with it.
With timings 19, 20, 21, 22, .... 30 it is a little better or worst.
But problem is - when I changed to FC to MWii or KK 2.0 enignes on 18degree are cold, ESC are worm. Power consumption is still to big (timings will help) but it is much better than with AQ !!!
I ask HK for proper timings and get 7-15 degree so 13 degree is best for all of tested.
I checked (read) that KK 2.0 works with PWM freq at 490 Hz. SimonK works with up to 500Hz, and AQ 400Hz.
How to (where in code) change PWM frequency for motor PWM frequency?
May be there is soem kind of parameter in "All parameter GUI" I can changed to?
Please advise.
