You are probably slamming your collective up and down. Watch the bar that fills up and look at which point your helicopter takes off.

But it seems you should just use the standard flight model since you are confused with the more realistic, advanced flight model.

Menu -> Options -> Game -> *right side* = 'advanced'- set it to 'standard'

Try slamming your collective up in a real helicopter and call me if you survive it. It will either boost uncontrolable into the air, or/and would rip your blades and maybe even engine apart.

Thanks, I'll take a look at it when I get home. I didn't set that so it must have done it by itself. But it still doesn't fully explain why it SOMETIMES won't do the advanced model. I can understand why it won't work on modded choppers by default.

As for realism, I'm playing with a keyboard so yea... don't want a sim. Just wana fly choppers like I always have in ArmA.

EDIT: That worked, thanks.

There is also an optional key bind for engine on in controls. I set mine to ctrl + E. For Rotorlib I recommend using a analogue throttle for collective input, if you ever want to make the switch back to Rotorlib.

Yea I have the engine on option keybound already and don't have any intention of using the advanced flight model any time soon as I was fine with how the helicopters were on the old flight model. That's about as realistic as I personally want it. Either way, I have no gaming controllers so it would be really awkward on keyboard.
