RD Logics SHO conversion

[mickeymoose]

Hi everyone, I just picked up an RD Logics SHO 1/8 buggy roller on ebay for cheap, my lhs stocks all the parts for them. I have a Feigao 7Xl c can laying around that I bought against my better judgement, and was wonderingwhat you guys think about using that on 4s with a 12t or 13tpinion and 46t center diff gear? or should I finally put the 7XL up for sale and go with a 8 or even 9XL? I'm also thinking MM forthe esc. Thanks all opinions welcome, but experience preferred.
