So I got this truggy from ebay brand new for $225 shipped

and need some help deciding on a few things.
ESC and motor? I'm thinking MMM with 2200KV, but the RX8 is looking really nice right now. I like that Tekin has a bigger motor selection. Then again, is it worth the higher price - programmer is even extra!
I want to run 6S and go 50+ mph. With 2200KV, I would use 13T pinion; if RX8, then 1700KV with 17T. Either one with the stock spur. I don't think it would run hot, but that's just a speculation.
I want to use Mike's motor mount and battery trays, but together, they're already $115. Steep, but looks really nice.
Then, I want to do it up like
Arct1k's.
What do you guys think? More pictures
