I have been flying this plane with a small gasser (McCullough 33 cc). Not enough. Just purchased a 35CC MVVS. Check out the specs. The guy at Morrishoobies.com knew all about this plane (he has one) and says this is a great match.
I hear these engines are amazing. 20 lbs of thrust!!
Love the plane. Built like a tank.
