I learned to fly this summer using this plane with 61FX.

The plane has one design flaw that I have found - at least with mine. At certain RPMs the wood frame that extends beside the engine mounts rattles loudly. It was a real frightenening sound and it took me a while to figure out what was going on.

I shimmed it with wooden shims between the engine mount and the wooden frame (with a healthy dose of epoxy). No more rattle.

FWIW I thought takeoffs were a little underpowered but I'm a newbie so what do I know. The takeoff could also be the grass field I use (grass is always too long and boy is it hard on the nose gear).

Got any pictures of that twin conversion - I'd love to see it!
