RE: mamba max 5700kv
Wow you go all the way to middletown OH for parts. There's a Hobbytown in Cincinatti u know. Don't know if they are as good as middletown tho.
But like I said even my CC 4600KV motor get's pretty hot. Chances are you'll need an alum trans case to help manage the motor temps. I know I had to get one for the slash to keep temps at bay even geared 15/90 it was getting 170 in like 10 minutes on 2s lipo.
2s and 3s lipo is what you want for insane speeds. I get my lipos from spcracing.com. They have good prices and the packs have great punch.
I'm in Boone County BTW.
