I put a magnum 61fs on mine and it didnt cut it...I sent the engine back to Global two weeks ago and havent heard from them yet. I put a new Saito 72 on mine and it flys great...hovers at about 1/2 throttle and pulls out fine. This plane flys great...does all the 3D that I'm capable of..waterfalls, elevators flatspins, harriers etc...the landing gear is too flexible so I cut to fit, another one I had and put larger foam wheels on it for our bumpy grass field. DONT GO WITH THE MAGNUM 61. Put the money toward the ys63 or saito 72. Buy cheap, buy twice!!
