RE: GP Patriot 40 Kit Build
A tuned pipe makes this plane come alive. With a side exhaust engine you will have to mount header and pipe to get an idea of locaton for pipe holder. I mounted a hard balsa block under the wing sheeting somehow to help hold the screw during the building process, but now I can't remember just how I did this. Most of the flying with this plane will be full throttle or not less than half throttle so that is where the tuned pipe helps the most. The extra sound of a tuned pipe is nice also.
