what type of 'practical' motor is this you're talking about
I've got Neu energy packs, they're pretty solid. I have heard some mixed reports on the quality of maxamps packs, especially for the price
I quite like the MMM, its way easier to program and update than the MGM, however the MGM is rated WAAY higher, so thats the one i will probably go with. I actually got a Novak 10t pinion, to fit a larger spur i had to cut notches in the frame rails, but now it runs really well.
What truggy diffs did you end up getting, the RCM hybrids? Be sure to post some pics of these standoffs you're getting made up, which LHS is making them for you?
A bigmaxx would look badazz mounted on your G3R, havent heard anything bad about them, what others are you considering, just the larger Neu's?
