Hi, I built a QAV 250 clone. I am running emax 2204 with emax 12A esc's. I had one set of 6030 props that I busted, however it seemed I was getting pretty good performance out of them until one exploded in mid flight. Luckily I was only about 2 feet off the ground. I switched to GF 5030's and they seem to be fine, but I don't think that I get as much lift out of them and I have to use a lot more throttle to get it off the ground. I was reading some forums and some said that the 6030's are to much for the 12A esc's. Any thoughts on this?
