Hi, I am using a Saito .56 and it is just perfect for the way I fly. My friend has a saito .72 on his. He has a bomb drop trap door and he also has a rocket launch system on the wings. His has ailerons with a much flatter wing and is set up as a taildragger. Mine is bone stock but if I ever "rekit it" I'll make some mods to it. Goodluck with the build.
