flux gearing suggestions and high speed idler

[Semi Pro]

im sure you know that motor isnt going to last long,and neither will the mmp

your really should looking getting a quality motor and a mmm or rx8

personaly i wouldnt run 30k in the diffs much less 50k, it puts to much strain on the pins and they will fail often, alittle wheel spin will make the diffs last alot longer and the truck will turn much better too
