Hello all,
Made a simple 3 speed electric plane and thought you guys might be interested.
To change speed. Ive set action groups to the two reaction wheels that power the 2 blade prop. From the plane switch to the prop using either [ or ]. Now press either 1 or 2 to slow the motor. Press both 1 and 2 to set the motor to idle for landing. Switch back to the plane with [ or ]. It does takes a few times to get used to but soon becomes second nature.

Cheers.
