I have a global ultimate with a Magnum 91FS, APC 14-6 Prop Smoke system 6 Mini HI TQ servos and a 5 Cell 6volt battery.
I have ran the engine for brake in but haven't flown it yet at 1/2 throttle the plane seems to hover in the vertical position and at full power looks like it will have great vertical acceleration. Thats at 2800 feet in the mojave desert.
