I have the SA F-20 and there are a few threads on it. But, it's a great plane! I have around a hundred flights on mine with an older TT .46 and put a fresh TT pro .46 with a JETT muffler. Even though it has a fixed gear, it's still fast! I clocked it at 132 with a slight tail wind in level flight. It flies like it's on rails. Very smooth. Very strong. You may want to lock the rudder out like I did, because I read that they like to flutter at high speeds. The only thing you'll have to get used to is the speed, just stay ahead of were it's going!
