Status: offline 		What prop are you guys running on the Hacker 20-20L and the Extra Stiffy? The manual says an 11x4.7, but serveral guys have told me that is too much for that motor. Is a 10x4.7 a better choice?

I like the apc 10 X 4e or 10 X 3.8e. The motor will pull more, but the quality of flight goes down IMHO.
