No, it just makes it land and takeoff faster. You must also have enough power to get it up to that speed. Do you fly now? Did you need a new airplane to work yourself over those 'I just SOLO'd and now I'm dangerous' blues? Durastick is about the only thing that takes more abuse than a SPAD and that's only because of the wing being solid foam. That's also the reason it doesn't fly as well. You can build a SPAD RNAF type wing the same dimensions as the Duraplane wing and just use it instead and the plane will fly slower as it will be lighter. You might have to move the wing fore or aft to get the CG the same but you can use the fuse with no problems.
