RE: Maiden Flight of GP Cub with GP floats
Those floats are widely regarded for being heavy and oversized. Several shops make completely delightful foam-cored floats that weigh a quarter of what those weigh, and when you subtract he weight of wheels there is hardly a difference in the weight of the plane with floats. Your plane will regain its aerobatic abilities. High-wing planes usually become somewhat MORE capable of inverted flight with floats.
