magic will do a very sloppy knife edge if you use the engine to your advantge enter a hover and let it slide over alittle to one side and work the throttle to help keep it up, its more of a tail slide than a knife edge oo btw that 12.25 x 3.75 is not the best prop i ve found my .46s allow for good 3d and better throttle response using APC 11.5x4 but this is just my .02 cents btw the magic flat spins really well and is a hovering machine!!!! perfect 3d
