i like these topic titles that lead you thinking completey off track.... buttons file for helicopters or something!?

actually to give a hint, there are flight sim joysticks that have multiple throttle / trimm devices. These should work i think. one driver for the device.
do you have such a thing or do you mean "second joystick"? I doubt IL2 supports multiple joysticks. Others may know more though...
