Brian, you are right most airplanes, kit ,scratch. or ARF are over built. The thing you have to remember is the designer does not have control over how the airplane is going to be flown. When you are selling to the masses you have to keep this in mind. That guy at the flying field how pushes the throttle stick all the way forward and leaves it might buy one too. If you scratch build or kit bash you can build the airplane as light as you want it, and if it comes apart in the air you know to build it a little stronger next time. Tom
