There's a prototype 21.5x10.5 also.

Hi Adrian, and thanks for the info. Are you saying that you no longer point the nose up, then throttle up like you used to do? That now the model gets slow enough to need throttle up before the corner?
The 20.5x10 PN should be doing a fine job on the 185, on moderate nitro. What exactly are the slightly bigger props supposed to deliver? A slower presentation possibly? Or something else?
