My two cents for what it's worth........follow all of "mike109" from down under's suggestions plus one more, don't deploy the flaps untill after you are comfortable flying the plane (many flights) and then do at altitude as a test to see what effect they have on pitch. Some airplanes pitch up with flaps some pitch down, some don't change. If your flying with a computer radio elevator changes can be programed in to compensate for the pitch change. Wait till later to play with the flaps as they are not needed on a Kadet Sr. I have a 1/5 scale Cessna that pitches up with flaps and a similer sized Kadet Sr that pitches down big time with flaps. For learning to fly a fixed wing aircraft pretend flaps are not there!!
