I have 2 4*60's and love both of them. I have an ARF with a GMS 76 on it and it flies great it has lots of power and will do anything that I am capable of. The other one was built from a kit and has a Magnum 91 four stroke on it. This is my favorite plane to fly. The four stroke engine is the best one for this plane. It has unlimited verticle an will flat out haul.
