Are we able to replace the stock controller for the P2 Vision with the new one with the left dial button?  it only says for P2 Vision+

Yes you can, first bind it to the quad then go into the phantom asst and change it to the new type, then connect your RC to the RC ASST software and run a calibration of the sticks and then calibrate the wheel with the X1 calibration button then connect your quad to the phantom asst software turn on the RC and calibrate the sticks and the wheel in there.

How to bind the remote controller:
