Since this is the 3d forum, I assume you will want hovering performance also. There is a review on a OMP bipe here on RCU that uses a G90 for power. Check it out.
I emailed him about what prop he had on it a few days ago and he is using a 15x4W APC. This is the prop that I will be getting for my goldberg extra. Only down side is it costs $11 each. I will be careful not to break too many of those.
