I have a Magnum 1.20 in mine and it flies great. I have no complaints whatsoever. In fact, it has become my windy day flyer now. My only complaint is the tail wheel. It is rather weak, but bug deal, most of my planes don't even have a tail wheel anymore. With the size of the rudder it is not needed.
Sorry about your experience Danny. Segull models have a rather good reputation in durability and quality. That package sounded like trouble from the start.
