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.
