[SOLVED] Custom Turbofan Counter-spin Issues (Using Joystick Bases and free-spin rotators)

24.3k RobertsAeronautics  27 days ago

If you don't already know, I'm making a new airliner, but I'm having issues with the engine, specifically the fan. It uses a joystick base to spin, and a rotator to cancel out torque. When I stop the joystick base spinning, the rotator keeps spinning, and the fan starting spinning the wrong way. I've tried replacing the rotator with another joystick base to provide counter torque (it solved the spinning problem, but didn't cancel out the torque properly), and adding a 2nd rotator to cancel out the unwanted counter-spinning (didn't work).

The fan idles at c. 850–1000 RPM, and c. 4000 RPM at full throttle.

Could someone help fix this?

Solved: I subtracted the rotator RPM from the FT function to cancel out the counter-spin.
