Help! I'm a Girl and Know Nothing About r/c!!

I wouldn't advice the use of a 9L motor; they tend to run hot pretty easy; i understand you are on a budget, but the 9L is a hot running motor on 4S lipo's.

The mega motor is nice.

If you got the room for it, i would go 8/9XL and gear it up a bit more.

Don't know if you've seen the speed calculator BrianG made, it's in his signature and it works like a charm.
