Hello Tomas.
I still have the problem that the motor jerks when it is switched on before it starts up slowly, I've tried a lot of settings, I just can't get it away, the only setting where it works properly is when I turn it on Set "very slow", but then the motor simply takes too long to reach the set speed. I have currently set it to "slow" where the motor jerks again, the run-up time would be fine!
I have the following hard goods:
Spirit RS (Gov Mode)
YGE 205 HVT controller
Scorpion 4525 engine
What could be the mistake?

Hello,

it could be needed to set different mode in the ESC settings. So that Initial Power will be lowered.

You can use Spoolup Rampup to minimize this effect. If there is delay, you have to increase the value.
Smooth spoolup require configuration on both sides, with YGE it should be possible.
Have you changed YGE parameters in some way?

Settings can be different than when using YGE Governor.

Hello tomas, I set the starting current to min 1 amp and max to 3 amps on the Yge. The test was a little better but still a jolt. If I further reduce the starting current at max to 2 amps or 1 amp, the motor will run no longer going on
