If you want to hover around 40-50% for a plane that heavy, go with a Himax HC2812-1080. I absolutely love that motor. It will run fine on that setup. I always use an APC 11x4.7 prop on it, and it gets a bit warm on 3 cells, 2100mah, but it doesn't get any warmer. An upgrade for longer flights would be a TP 2100 mah 3 cell. I normally get about 15+ minutes of flying on it, and I've used it in about 6 planes, weighing from 14oz. all the way up to a 28oz. plane.
