I have been having an issue with my throttle.
I have attached my Spirit file and my Jeti model file.

I have my Castle ESC set for fixed end points at the moment, but will change it to Airplane mode once I get this sorted and start to use the spirit governor.
The throttle curve is linear 0, 50, 100.
But the throttle response is like this, I will go from 0, the when I get to 50 on the curve I actualy have 100% throttle, then when I get to approximately 55% on the curve, you can hear the motor rpm drop slightly, then as you carry on through the throttle curve back to 100%, you have full motor RPM again.

The first thing I checked was the throttle curve, as I said above it is a straight linear curve. Then I attempted to re-calibrate the esc, it wont let me calibrate the top end point, but when I bring the stick back down, I can calibrate the lower end point.

Could the throttle sensor be giving me this problem?

I have looked at what would be the obvious, can someone shed some light on this please.

Hello,

the problem is caused, because you have Governor enabled in the unit.

If you are using governor, then using a throttle curve other than flat is not optimal.
