well, i would spend $700, but if you want lots of power and cheap look at this stuff.
its just an option, but gives you ideas.
motor is a kb45xl. they have a 6mm shaft. easily can be ground down to 5mm for readily availible pinions. =$55+shipping

you'll need a ubec to go with this. there are several at united hobbies for under $20

batteries you can use the wonderful a123's. pick up a dewalt dc9360 for $140 on ebay and that'll give you 10s1p which is 33v's and will spin that motor to 39krpm.
charger, there are several a123 chargers out there. it will be eaiser to configure your packs into 2 5s1p's and charge them that way.
here's one option, although there are better out there. =$69.95

now add custom motor mount, and a pinion for $30 and you're set.

i get $511.90 with what i listed here. you'll get way more power than nitro has ever given you, 10-15min run time, batteries that'll charge up in <15min with a better charger, and reliable running.
