don't tie to carrier in case it gets caught by the chain, or wrapped around the axel, i had a person tell me that they were doing that it caught the axel chain and frame, ripped the grab bar off and the rope cut right thru the freme and bent the crap out of the thing and just ruined it, and this was a crappy chinese one, imagine what blaster power would do, i pull a thing like mx snadracer does because of the brakes and steering.
