For $300, thats pretty much your only choice. Better motors cost alot more, in the $150-$250 region, unless you can find something second hand. Esc wise, again, if you want to run a higher voltage, you will need to spend alot more- the Quark 125b (monsterpro) is about $225 I think, but will need the thermal mod done at some point in the future. if you can wait a couple months, the MMM will be released (hopefully), and that will be $300 or less for the esc, ubec and neu 1515 1y type motor, which is perfect for 12-14 cells, or 4-5s lipo. Hate to say it, but performance = $$$....
