If you go to the OMP web site they now have a video of the GS540 hovering with the OS160 on a pipe. It appeared to be plenty of power. It pulls out of a hover with authority. Although i went ahead and bought the Moki 2.10 I'm convinced that the 160 is probably a better choice. less weight, lower fuel consumption and plenty of power to pull this bird around. My recommendation is keep it light.
