Hi DeadintheHead I have had mine built for some time now. I have the Magnum 52 XLS with a 12x4 and hardly ever use 3/4 to full throttle. I also balanced at 4'' so inverted takes almost no up compensation. I am enjoying this plane allot. It is almost like a rocket! and hovers nicely. I still need to play with the radio tho so i can get knife edge a little easier it likes to roll out.[sm=spinnyeyes.gif][sm=spinnyeyes.gif][sm=spinnyeyes.gif][sm=spinnyeyes.gif]
