So far im happy with it. im running a 15/46 gear & the speed looked good. I'll have to take it to the track to see if it needs more gear. I was not using the rc- monster heat sink.

Make sure you seal your 9920. I burnt my 3695 after running it in a baseball field. My friend at Flextronics said, "It is amazing what a few little rocks do to electronics." It was funny how he said it though. I think the same issue happened with my Quark which was running fine, but when I went to another baseball field it went up in smoke. I also saw a video in youtube of a Japanese guy who made a battery using what it looked to be stone that he ground using a coffee grinder (free energy). BTW This is not an issue with controllers that uses conformal coating.
