I'm in year number 5 flying 3D aerobats and fun flys for the last 3 years. I was caught off guard with this plane. I figured I'd be flying it from a lawn chair. It took a few seconds for me to catch up with it, then it was fine. I just am saying be ready for it. Depending on how much pressure there is between the wire and the tank, it may eventually cause trouble. Maybe slide a piece of 1/64 ply in between and silicon glue it to the tank or something. Then again it may not become an issue at all. Get ready for 10 foot diameter loops, it's a blast to loop this one. When you're used to it try it from about 4 feet high and listen to them gasp when the plane does it. Then do it again and idle the engine at the top and keep it idle. If yours turns out like mine, it will do it no problem. Then land in a head wind with no foreward movement. Then take off with no foreward movement. The plane does some pretty cool stuff. You will need good rudder skills to fly it slowly. The ailerons are nothing but trouble when you are flying at the slow end of the flight envelope. It's all rudder and elevator then. I like 1/4 throttle rudder eights mid field, at head high, right at dusk while the other guys are packing their trucks. But that's just me!
