I am using the Frsky in my Valiant w/DLE 35 as well as My Escapade ,MX DLE 35 also, not exactly cheap airplanes. They are compatible with my Hitec 9 channel. They have performed flawlessly in these planes and others I have owned in the past several years. I have a 30 cc Spitfire coming from Tower and It will have a Frsky in it! These Receivers are a real value in my humble opinion.
