Yes, you did miss the point of my post. ''Wing Loading'' is the key to performance of any scale aircraft. weather WWII or aerobatic models. Just take a look at monster 3D models. What I'm trying to convey is simple. Keep the weight down and all those nasty traits of a heavy loaded warbird will go away. Going back to the times I flew aerial targets we han a request to increase our air speed by 25% for a high speed variant of our basic target using the same engine and propellor. The first thing we did was get rid of weight. We meet the new requirement with a few additional airfoil changes but the key ingredient was the weight factor. This applies to our models as well. Decrease weight equates to increase performance.
OK, I guess that is so much a given that I overlooked it. However, in the case of the war bird (this forum), weight enhances the look of the plane in the air. Just ask Meister about weight and their P-47. Dino will tell you that the lighter 35lb versions don't fly as well as the 50lb ones do. The heavier planes look more solid in their track, are more graceful in maneuvers, and bleed off speed in the vertical more realistically - like their big brothers.
In the case of the aerobatic plane, absolutely!!! Get the weight off, and go fly 3D all day.
