I'm looking for a reasonably priced P-51 arf and 4 stroke motor setup, preferably .60 to 1.20 size. Also, how good are magnum 4 strokes? I am considering one for power as they have a reasonable price. I have always used 2 strokes, but would like to make a change. This will be my first warbird as I currently fly 3-d models. Because I am used to 3-d performance, I am afraid of airframe issues. I had considered the hanger 9 model, but I am now leery as I have heard several stories of their airframes failing. I know I tend to throw planes around and put them under high stress. Any advise would be appreciated.
