Hey

It depends on the aircraft.


Some planes require a little bit of aileron to get it going , like fun fly's for example. My Top Cap wont torque roll unless I give it aileron , it will just hover.

Larger high torque gas engines seem to be more willing to torque roll.

My Sukhoi torque's on its own , As soon as I pop it into a hover it starts to torque roll.

It all depends on the plane , the motor , thrust , etc.
