Seems like your heading down the "speed road" here. I suggest you get a 60 size stick, It may be high wing but it can be hot with .90 on it. The reason for this is that third plane you want which may be a warbird or Shoestring or some hot racer. You can use the same engine if you want and keep the plane just in case.

I cannot tell you how many people I have seen quit the hobby that are doing this the way you are. Part of learning is the process of how to react when something goes wrong. Any idiot can fly these things but when something goes wrong, those who paid there dues will take their plane home in one piece instead of a garbage bag
