Hobbywing platinum 120A v4 ESC cutting off at full power
Im new to electric planes, and was hoping someone might shed some light on a few bugs in my setup
My throttle response is docile and not snappy like i see in videos, and at full throttle the motor resets for a split second.
I have the following setup
*pilot RC 67" Laser
*4200mah 6s 70c pack
*Hobbywing platinum 120A V4 ESC
*disconnected BEC, running a separate RX pack
*Dualsky GA2000.4
*pilot RC 18x10 electric wood prop
Any ideas how to fix the slow throttle and the full throttle power cut?
TIA

More info is needed for debugging:
Current at WOT (wide open throttle)
Same for RPM and battery voltage drop
Motor velocity konstant Kv (expressed in rpm/volt, it has a massive effect, cubed, on current and power drawn)
Note that Kv says nothing about max.continuous power, the motor in your toothbrush and the the motors in a 1:1 train can have same Kv.
With the above info you can try
