thanks for the info. i was thinking of getting one of the ARTR kits. you have to buy the motor and servo, batteries and contoller, but it looks like i comes a little more set up for crawling. that way i could just get the motor and everything else that would make it a better crawler right off the bat.http://www.rcplanet.com/Unassembled_Rock_Crawler_s/1581.htm this seems like a pretty good deal if you have to change the motor anyways
Actually had the ARTR kit been available when I went to buy mine I probably would have done that instead. My friend just got the ARTR kit and he only ended spending $60 more than I did initially and his is pretty well set up. Its already got the nice steering arms and tie rods, bent rear links and alum straight front links and it comes with better tires than the Rock Lizards the RTR kit comes with. So he just bought the 55 T motor and the upgraded steering servo and stuff and ended up with a really nice rig. The ARTR is really the way to go if you want to get a more capable crawler right off the bat and skip having to upgrade the steering servo, steering arms and tie rods, motor etc.
