RE: What engine for a H9 Cap 232 1.20(1/4 scale)
I had a Saito 180 in mine. It would go verticle on takeoff for as long as you wanted. I did put a 24 oz. tank in and would fly for 9 min+ depending on throttle managment. The 220 would be crazy power I would think. I would love to have another. Mine met an untimely demise. I hit the wind sock pole after over 1500 flights. That's probably a low estimate.
