I have recently been using the internal governor of the spirit pro, the regulator is a Scorpion trinibus 200 in external regulator mode.
it works quite well, but I have two small problems:
1.) If the engine is turned off and then turned on again, then the engine is suddenly slowed down before it starts up again. It does not matter whether the engine with the main switch or with the bailout switch off and on, the problem only occurs when the engine is not completely stopped when switching back on.
2nd) the run up after the bailout is a bit strange, I have set 3 sec, while the rotor drives up to about two thirds of normal gas quickly, but the last third is then very sudden, sodas the rear turns away.

Ask for solutions, thank you

1) If throttle will go under 12% then rotor will be spooled up in a normal way, as from 0%. If % is higher than autorotation bailout is engaged.
2) Can you describe how Autorotation Bailout is engaged, please?

1) The problem is not the 12%, the problem is, the engine is decelerated suddenly, if he is not yet and I turn on too fast again. The startup then begins correctly. But the braking of the engine, I find very strange.
2) The autorotation bailout is activated with a gas straight with 13%, this gas straight is on a switch, as I have with all other controllers.
After the completion of bailout, the engine will ramp up normally quickly, but just before reaching the preset speed, the controller makes a sudden jerk up instead of steadily accelerating.

1) I am sorry but I dont understand you very well. The goal is to switch from idle RPM to flight RPM. If you will engage Throttle Hold the motor must shutdown immediately. If not then something wrong is configured in your radio.

2) Please attach your settings. It is very likely that your ESC is taking control of spoolup too.

My controller (Scorpion Trinibus 200) is set to External Governor and therefore does not regulate anything.
Starting rate: Fast
Motor startup: 200us
Speed controller response: 8
Holding power: 7
Holding limit: 90%

Autorotation time 3sec
