build a gmaxx and i need help

[Maxxrickard]

i am not shure about the batt. 6 or 5s? yes i know that neil recommend 5s and i think about it. but, i guy in my rc-store said it wasnt possible to make a serie with 2+3s.
or maybe use 5s and put it in parallel.

the question is, will it be to heavy with dual 5s? and should i choose 30 c instead of 25c?


yes the body is my problem now. i really like the "suv"look. ex. proline escalade or hot bodies dodge durango hemi body. but i cant find them. i bought the hemi body from the "quich tech hobby" 18/9 but i havent get it yet... have mailed them 5 times...
i have 1980 Chevy® Pick-up from proline but i dont like it.

i like the truck look more than the truggy look.suggestions?
