I picked up a Rambler 45 today. what engines seem to work well on this plane? They recommend something in the .46 range but the plane seems a little on the large side for that. I'm sure it would fly it fine I guess. I was thinking a .61 or a 4-stroke of some sort though.

Also, how are the retracts? I have the WM .46 size P-51 and they are pretty weak. I'll admit that I've landed it hard a time or two but they seem like they'll bend just from the weight of the plane alone.
