Don't have anything against coro, other than the fact I have to drive 100 miles one way to buy it and that place in Kansas takes forever to fill orders, like 3 to 4 weeks sometimes.

Like I said twice already, I wasn't trying to start a debate over coro vs foam. What ever floats your boat man.

Oh, and sharp leading edges on balsa or foam wings make a plane pitch sensitive too, it decreases the angle of attach where the wing starts to stall. It isn't something unique to a coro wing.
