You have a loaded question here. Wing loading is somewhat dependant upon the size of the plane. A plane with a 48" wingspan would not fly very well with a wing loading of 32 oz/sq ft, but a plane with a 105" wingspan would be more like a kite at that same loading. I think, and I can only say this from my limited experience, that you should have a pretty decent wing loading for the plane you have. Wouldn't have been my choice for an engine on an aerobatic plane though. Something like the BME 50 would have equivelant power and would weigh much less yielding a slightly better loading.
