I.too have a Rascal 40 and love it. I put a .56 Saito in mine, with a 12-6 prop, and it goes like stink, has good basic aerobatic ability, and looks cool, too. I had a problem ,the clunk came off the fuel pickup early on, and I stalled and crunched the wing and cabin; it was repairable, but I had to strip the cover. I re-covered it in white 21st Century fabric and painted it. If I can get a few extra bucks, I'm gonna get the 110 size. I am finishing a set of floats for the 40 now, out to be great off the water.
