This is a build update. I finally got my 335mm and 325mm blades in. I did 3 test hovers with the 335's adjusting pitch settings etc...I had heat probs and she was a little sloppy in handling. I could not get it where it would fly good with the 335mm blades. Then, I put on the 325mm blades and it was a major improvement in handling and lowering the heat problem. My batteries are about a year old, they're pretty beat up and tired...many uses from them. Anyway...it looks for now like I stick with 325mm because it's like putting 315mm on a stock bird...just a major improvement.....I'll up date as it progresses and I find the sweet spot as well as add pics(still trying to figure out this camera).
