You left out the number one choice at our field, YS 110. Believe it or not that is one of the most common combos at our field. We have a group of guys that fly them regularly in a loose formation on average 5 at a time. Not all of them are the WM Mustang but I'd say more than half choose that 40 size warbird for it's good flying characteristics. Because of the formation flying a LOT of others try and emulate them and also have the YS110/WM Mustang combo. With the right APC prop and YS20/20 fuel they do about 130mph and slow down like a trainer for landing.
