Thanks ! I'll check them out. I have been practicing inverted flying and knife edges on the RF 2 sim. Im sure the knife edge will be not so easy in real life, but short straight passes should be a piece of cake. On the sim I can go to knife edge on take off, and fly the whole flight that way now. lol I actually got burned out on it last night, and now im back to normal flight again. I like flying my planes just barely above tip stall speed the best, it just looks neat, and is sooooo much fun. I hardly ever fly over 2/3 throttle. Just avove idle is way more entertaining for me.
