I see your point and agree that airfoil thickness would be a good thing to list against the various models along with some sort of description about high and low speed handling.

I'm not sure what the rules in SPA are about changing the airfoil. Many viewers of this forum are interested in keeping a model that is SPA (or BPA?) legal.

So David: are you going to start some sort of a Matrix? I volunteer to provide each of the parameters for the Deception and Calypso if you do. I could also provide Sig Mayhem which would be an example of extremely low wing loading and of large control surface size, however it is NOT a classic pattern ship (as you know).
