RE: need help with sundowner 50
I think I would of had to drill new holes but I decided to go ahead and put my .46 thunder tiger in and see how it did, I know it runs great and is reliable but if it dont work out I think I'll go get a new engine, something along the lines of a .75 like russm said, or maybe a 80 size saito. Ill let you guys know how the .46 works out. Might fly it today if the wind calms down a little.
