It looks a little short coupled.

Dennis,
She isn't a PA airplane. The airplane is designed to be a step up from profile ships for fun flying. It also has no flaps. Clean, simple, good wing.

The ratio of distance from CG to hinge line divided by the distance from nose to CG for the Bill Werwage World Championship P 47 is 1.87 The elevators for the P 47 have to overcome the opposite pitch moment of the flaps. The same ratio for the Sport 45 is 1.72 . It is shorter, but it is not designed for stunt competition.
