RE: Prop for H9 Alpha 40
I have a 11x6 on mine and I've tried a 10x6 and 10x7. I like the 11x6 the best but had to up the nose tire 2 sizes and I bent the mains a tad to lower them. She fly's great with it and I can get 20min a tank at half throttle. Lands WAY easier with my modifications that I made to the main gear, no more bouncing due to the stupid wire gear.
