I have bindings set for ‘governor on’ and ‘ governor off’ and it works properly. Haven’t tried ‘governor toggle’
You are absolutely correct about the throttle axis.
THERE SHOULD NOT BE ANYTHING BOUND FOR HELICOPTERS TO THROTTLE OR PROPELLER.
‘SET HELICOPTER THROTTLE AXIS’ and ‘COLLECTIVE AXIS’ are the proper bindings and they work as they should in the R66 and Cabri G2.
The H125 does not have a modeled throttle axis. Use the mouse in cockpit to click it from ‘idle’ to ‘flight’
