I believe the Lama V3 has mixing turned on in the controller and you have to turn the mixing off using dip switches to use it in FMS.

The problem of course, is you need to set it back again to fly your heli.

So, perhaps a $5 dual joystick is in order. Works just fine for training on FMS.

Or you can get a $20 SIM controller that will work.
