I am currently building a patriot kit...

I am taking pics of it as I go along and it a pretty fast building kit... It is the third day so far and I am already finished with one of the wing panels and the tail feathers..... Ill tell you its allot of sanding...

I got a question for you guys.....

If you build the plane by only following the manuel and don't add any carbon fibers and so on it can handle the stress, right? and If yes about what speeds do you think it could take?
