I use most everything supplied in the kit, The plane sits down like a feather floating on a breeze, if you bend the LG you have really done something wrong. Last month I built one completely stock, most of the others I have cut out wing bays depending on how well the student can fly. I also add to the rudder if the student is really good and getting into a lot of stunt flying. I have added to the elevator also but it isn't really required. Even in stock form the plane can do stunts pretty well. I have been using the 4* 60 as a teaching aid to building for my students first kit. Very nice build and no surprises. Good choice!!
