Jim,
Here in Canada we can declare whatever gross weight we want (wisely or
not). Seeing that the added weight is itself in the wing and results in no
increased stresses, I figure I could simply increase the gross with long
wings by the same 100lbs without penalty (assuming enough HP). No?
Curious, how much floor-spar clearance is there with the glider spars vs
short wings? Is there a possibility that a modified/redesigned drive tube
could still work for both?
cheers,
Pete
