I can't believe the number of people that recommend a Losi crawler to a "1st TIME" buyer. They aren't bad BUT,,,,, they are using standard hardware, not metric which makes is hard to keep tools and "stuff" with out having more than the needed set of tools and extra fasteners. They've also got terrible worm gears and are more expensive in the end to modify.
Get the Axial Honcho or the RTC version, even the Venom Creeper is a good crawler that can hold up. check out rccrawler.com to get all the info you could want for crawling.
