Here is a picture of my 4*60 with an OS91 surpass for the engine. I took a Super Mario bobblehead doll and modified it for the pilot. The plane came out a little heavy, but I expected it with the weight that mario came out even after modifications. I go along with others on this plane. I love flying it and it remains one of my favorite planes. It is steady in the wind and in landing, I set it up with flaperons for a little more lift and just keep a couple of clicks in the throttle.
