I have been flying the FT Cub with a 3S and stock motor Radial 2212-1050kV and 9x4.5 prop. After a few minutes on a fresh battery the flight characteristics are slow to sluggish. Don’t get me wrong, it’s a fun slow flying plane, but starts out with good zip and then peters off to a meander. I was wanting a bit more pep in my flights. I tried a 9x6 prop and man was that exciting. Too fast and difficult to handle but a good thrill even at slower speeds. Motor was noticeably hotter when checked at landing. Today I tried an 8x5 and I think this a perfect match. Good zip but not to the loss of control point, plays nice at slower speeds and goes from a slow and low approach to up up and away seamlessly and smooth. Will try a few more sizes but I Think the 8x5 is optimal.
