I have been playing around with one for about a month.... Magnum .52 four stroke with a 12.25x3.75 prop..... my CG is about 1 inch aft of the recommended range... I have a 6v battery in the first bay of the fuse.... I can hover the model at just below 3/4 throttle... the little Magnum has only 6 tanks through it.... I might try a bigger prop after a few more flights....

Harriers are sweet with the Magic Extra... and flatspins are OK... I think I need to take out some aileron throw to make them tighter.... Blenders are spot on.... I can hit 3 out 4 attempts on a blender with it.... not enough power for waterfalls (or at least with way I waterfall).... I haven't tried a knife edge spin... not enough power for knife edge loop.
