I got a 3 quick flights on mine this weekend.

OS 91FX, has more than enough power. 14-4 prop pulls it like MAD. Flys at 1/4 throttle. Very very easy to hover, almost too easy. I have massive throw in the ailerons and at different speeds, I am disappointed in the roll rate. Those wingtips may have to come off. Knife edge is great. A little pull to the belly, but not bad. Someone posted a KE wall. Its true, you can come by at a very low speed, and add a little power and go to full rate rudder and stand that thing UP!!! Best KE looping plane i have ever owned. Very stable plane to fly. Flat spins are flat and controllable with power. Waterfalls were a bit sloppy, but I it may be tail weight, I still have not balanced it yet.

More to come.
