well i know people rebuild there diff very often. I dont
but im not raceing like you i just use high temp red grease and it keeps it lubed up prety nice and prevents over heating so i dont rebuild them often and im stupid but i got a box of spare diff BBs from my evader and there from all the diffs i melted just in case i lose 1-2 in rebuilding them ( it happens) i can toss 1-2 in from the box and i space them out so its all ok. any ways nice paint job and i to am in the rebuilding process. im got a new servo rebuild the motor (due for a new piston/sleeve soon but i probly am geting a CV-R .12 for it and rebuilding the .18 as a backup motor
. any ways have fun and good luck.
