I'm running this motor on the Edge Shockflyer with the Tsunami ESC, 3-cell 340mah Lipo's. The Prop's I've tried are GWS 8x6, 9x4.7 and 10x4.7. My fave out of these is the 9x4.7. The 10 is good for prophanging with the large diameter, but it does reduce the flight time slightly, whereas the 8x6 doesn't get you out of trouble quite as quickly. Well pleased with it. 10 out of 10.
