It works only with 2 position switch on device (for me t-50cm3 throttle VPC) i set gears up and gears down to my switch. After cold start you need to take off and set device switch to up pos (gears up). You can just eject or crash and choice a new cold jet, at start if you see gears lever at raised (top) position the bug has happened. Even if you move gears lever to down position, after engine start gears will retract
