I am just finishing up a FT Alpha build and am having a strange issue with a Skypower ESC. I got several of these when Headsup was going out of business.
My overall setup - Skypower 20A ESC, Jumper R8 RX, Taranis QX7 radio, DLFPV 2205 2300KV motor. I have a throttle cut switch which forces throttle channel to -125, 3S battery)
I powered up the system and as soon as I "enabled" the throttle the motor started spinning (and that is why you test with props off). It was not a matter of needing to reverse the channel as I could ramp it up. I discovered in another thread that the ESC seems to re-calibrate itself on power-up. They suggested to set the switch to -100 (normal low throttle position). I did that and that resolved the issue with motor spinning when enabled. I then started to ramp up the throttle and just below 1/2 throttle the motor started "chattering". (Radio said throttle position was 1300)
I had a Skywalker ESC available from another build that used the Spektrum radio. I connected that all up and everything worked perfectly with both throttle cut connections (-125 and -100). I was able to go full throttle (2000 on radio) and the RPM's were definitely higher than the 1300 on the Skypower ESC.
Anyone have any thoughts on this. I was using the Skypower ESC as it had longer motor leads which worked better in the build.
Thanks
