If you have the Oculus Touch controllers try this setup: Use your rudder pedals for rudder, Touch tontrollers for virtual cyclic and collective Forget using your joystick, specially the cyclic.
I tried this with some success on fixed winged aircraft, but the lack of return force on the stick makes it sometimes tricky. But with the R22 it really shines. The virtual cyclic gives you a much bigger movement range and ultimately a much finer control. And being a helicopter you don't miss the return-to-centre force.
Really enjoying this!
