I have had a blast with this truck, mods so far are integy motor fan with heat sink, velion esc fan, rpm front a arms and a 6400 3s lipo. Freaky fast but I seem to break something everytime I take it out. First was the a arms and replaced with the rpm a arms, which I hear are great. Today I broke a rear drive shift, I know MIPS are supposed to be basically bullet proof but integy drives look good and way cheaper. Are the integy drive shafts worth it or or should I spend the bigs on mip?
