I flew the crap out of mine today and I am in love with it. Mine does better walls than my F90 ever did, and inverted flat spins are so cool. I am getting very brave with this plane as far as how much I do close to the ground. I have decided that mixing for KE is best done with the sticks, and the thing to remember is that only small amounts of rudder are needed for a good KE, and then there really is not such bad coupling. I'll try flaps for landing next time out. Right now, I like making nose high approaches and just walk it to the runway for a nice slow harrier type landing. My K&B 61 is really impressing me in this plane. I have a new Perry carb on it, so I'm sure that helps. Throttle response and spool up is instantaneous. The only thing I am lacking is that cool four stroke sound, and the extra weight of a four stroke. Mine goes vertical at about half throttle, and can roll all the way out of sight at full throttle. My receiver is next to the throttle servo and the battery is in the rear of the cockpit. CG is just behind the rear mark with the tank empty. I have an 8 oz tank that I swear I flew for 20 minutes trying to run it out of gas. I eventually did, but I know this thing would do fine on 6 0zs. I can keep this plane in a box only 150 feet cubed if I had to, and I usually do keep it right in front of me. Best flying, most maneuverable and most fun plane I have ever had, and that is largely due to the reasonable price tag.
