I'm using a 300 HDX 4200kv from helidirect. It's pretty cheap as far as brushless motors go, but it works well. It's aggressive, so I'd get a battery that puts out above 25A and a 30 or 40A esc. Right now I'm in the market for a good battery so I can't really recommend one. I was using a Mega Power 1350mAh 15C batt, for a while, but it got overdrawn a lot (only put out about 20 amps max), so now I'm just trying different batteries out. I'd go with Mega Power again and upgrade to 20C but they were out of stock last time I checked.
