I've been flying a lot of different foamies, 3DX, 300 Extra, VTO, etc. But I have been struggling to really hover properly. My LHS told me to prop down from 12x6 on my Himax 2014-4100 (3s1P) to 11x4.7. WOW that makes it a whole lot easier. You get a ton more control and things happen slower. Not to mention the added flight time. I can now do torque rolls and hover pretty well. If you're having trouble, try it out. Once I get it down, I'm sure I'll go back to 12x6 becuase it's so fun to climb like a rocket, but for now it's 11x4.7 for me.

Good Luck
