Just FYI, BL crawlers tend to cog quite a bit more than you might be used to with regular trucks. I would plan on adding a couple more capacitors and/or using a smaller pinion.
Latest update from cc for the esc, high/max start power, normal timing and 100% drag brake. I can shear the driveshafts off my comp before it cogs, and that was with a sidewinder esc.
