I just received a Great Planes Ultimate kit for fathers day. (One benefit of having children and a great wife.) I was wondering what engine I should use on it? I was thinking of the OS 50 or 46. I am trying to find a good used one on this site and was wondering what one to look for. Would an OS 61 FX be too much engine for this plane?

Thanks, Eric

I would go with the 60 size engine I flew one of these planes for around 2 years with a ys 45 and it flew very well it barely had unlimited vertical but it did. I since sold mine to a friend and he put a OS 61 in it and it goes up nicely if it were Me I would go with at least a 61.
