diffs crap out when the balls gall the rings, which has nothing to do with the pulley material. in fact, the schumacher diffs are quite solid, being that there are 12 balls in them (though i'd love to see 18), and the track diameter is larger than most diffs. (the further out the balls are, the more grip they have when drive torque is applied). they also use a bulletproof thrust assembly, that some of the xray guys have found out about.

i believe haynes is still on his original diff builds from february and he's run mod at a handful of events (carpet nats and canadian challenge).

seriously.
Trying to tell us something Mr. Goetz????

I bought a Thunder Power 4200 40C battery, feels like the 5000 and is smaller with plenty of room

Very nice.....Shock towers are awesome, has ceramic bearing, ceramic diff balls, diff is super light, chassis is 5 cell, spring steel used in shock mounting brackets, new blades on drive shafts, chassis is really nice and most important.....more room for electronics

It looks like the Mi4 has more room. Are you saying you tried the 4200's in the Mi3 or Mi4? I just bought 2 new 5200 40c so I'd prefer to have / make those fit, hopefully with a base plate.

most of these tips will still apply: http://www.rctech.net/forum/electric...acher-mi3.html

i can't stress enough how far a good build will go. if you don't build it like the 'pros', it isn't going to handle like theirs either (even if you copy the setups).

i'm sure there will emerge a few tips, specific to the mi4, but these will get most headed in the right direction.

I have to get mine and put a 'Pro-build' on it.
Diffs and shocks are my fav's; 30-40wt oil and 12 balls......right Goetz?
