Well, more info from the crawler guys:

raptorman57 - "IMHO,you're running the best ESC for crawling. Like John says to everyone.....Gear down,volt up. Thats how you make the outrunners work smoooooooth. Once you gear down,you'll see the problems go away. If your wheelspeed isn't where you want it,volt up to get it back.

I set all my Mamba's at 100% drag brake.

My start up power is on high.

You can also adjust the throttle and brake curve to fine tune it more to your likings."

JohnRobHolmes - "If you like to let off of the throttle and let it sit on inclines, put more drag brake in. They can get stuck into a downhill rolling mode if the geardown and voltage is too much to overcome."

Those were the most helpful ones, a couple people chimed in with the esc that I "should have got instead"......which doesn't do me any good anyway. I only used this MM esc because I wasn't using it in anything else and knew it'd be up to the abuse.

Travis, why? This one seems to have stupid torque even over geared, but is small enough that it's not hitting the Stealth tranny. Besides, doesn't that one have a 5mm shaft? It wasn't too hard to make the 4mm to 1/8" conversion, but 5mm to 1/8" would be a bit harder.....and I still think it's too big.

dude, i just now looked at those shots. those are great! looks like someone has a nice DSLR paired with a circular polarizer.

do you have, or have you tried, 4s a123's? esp. concerning the 'volt up to eliminate the problem' comment. i'm curious, as i plan to run 4s2p a123s in mine. i was worried it might be too much, but i also planned to gear down a lot.

You think the torque of your motor is stupid .

I have access to a machine shop at UCI (University of California, Irvine), where I go to school. Outrunners feature removable shafts, so I simply took the shaft out of the motor, and turned it from 5mm to 1/8". When it still had the 5mm shaft, I was running mod1 gears. Now with the 1/8" shaft, I occasionally have a problem with stripping 32p gears, and would strip out 48p spurs all the time.
