well, its time dependent.

its not impossible.

helecotors kind of move like harriers without moveable nossles.. actually I think i might do a helecotorised test version.

Im really very unsure on how rotor torque behaviour works..

..in the flight sim show near birmingham uk the other day I had ago of the helecotor sim - and got accused of treating it like an arcade :-)

that is to say - the behaviour is more complex than what I realised. but I think I basically grasp why it does the weird things it does.
