I have a Tamiya CC01 I bought for rock crawling, but I've noticed that when it gets stuck. Only 2 wheels will.move. 1 on front and 1 on back. I had a friend tell me to lock both diffs and then it'll be true 4wd? Is that the case? Also, it has a standard brushed motor and a standard brushed/brushless ESC. Which isn't fast but not sure on torque?... can you crawl on standard motor and esc? Cheers. Sent from my SM-G901F using Tapatalk
