At first glance of the X-Crawler all you see is all the Billet Aluminum and Stainless Steel.XTM Racing™ entered in a big way (no pun intended) bypassing the 2.2 class of rock crawlers and entering the fray of the Super Class. The X-Crawler comes pre-assembled in ARR (almost ready to run) form, all you need to do is add your electronics. The X-Crawler is close to having an all metal chassis, the only plastic are the shock ends and shock spring perches. XTM Racing™ has used steel hex head screws through out the X-Crawler, making it very important to disassemble your X-Crawler before you head to the rocks and reassemble using Loctite™ on all screws and bolts. This helps to keep the overall parts count to a minimum. The axles on the X-Crawler are configured in "Clodbuster" style, so each axle has its own transmission. The gears in the transmission are straight cut steel with an internal gear ratio of 21.3:1, use the included 8 tooth pinion, will result in the X-Crawler having a final drive ratio of 90.5:1. With the torque available from a 55-turn crawler motor and that final drive gear ratio will result in some serious rock crawling. As you would expect ball bearings are used throughout the axle and transmission. So, you are able to correctly set your gear mesh a thick transparent window covers the backside of the transmission. What I feel as to the most unique feature of the X-Crawler is its 4-link suspension. At first look you think that there is nothing new here, but upon closer examination you will see some things that other 4-link suspensions do not have. Yes, the 4-link is constructed in the traditional triangulated configuration. With the upper links being mounted to the upper sides of the chassis then angling to the center of the axles. This prevents the axles from swaying from side to side, while not limiting any articulation. The lower links are mounted to the lower sides of the chassis and angle outward slightly to the outer edges of the axles. What makes this 4-link suspension unique in the X-Crawler is the amount of adjustment that is available. Both the upper and lower links have four mounting holes on the chassis and the uppers have three on the axle. The aluminum threaded body shocks also have three upper mounting holes.   Create Your OwnNow here is the neat thing the lower shock mount is a clamp on the lower links. Just by sliding the clamp up or down the lower link you can adjust ride height and shock angle. With all the links having machined aluminum threaded rod ends, will give you an endless amount of suspension tune ability. XMT Racing™ has designed its own beadlock wheels for the X-Crawler. No weight was saved here, the wheels weigh in at 13.2 ounces that is just under 3 ounces short of being a full pound each. No need to add any weight to the wheels on this crawler. The beadlock wheels are a four piece design (two lock rings, rim and center section) and use a 14mm hex for compatibility with other monster trucks. These wheels are slightly smaller that a Maxx wheel, but will accept Maxx size tires. For example only: If you want to run 16-turn motors that draw 20 amps and spin at 40,000rpm. If you were to wire them in series they would draw 20 amps and spin at 20,000rpm instead of 40,000rpm and the ESC would see them as one 32-turn motor. Then if you were wire the same two motors in parallel, your ESC would see them as one 8-turn motor and would spin at 40,00rpms and the amp draw will double to 40 amps. All the companies that make crawler motors have great web sites and tech support that will help you to better understand how to wire your motors using one ESC. To get the most out of X-Crawler you do have to consider the radio you are going to use. If you are going to be doing any serious crawling you will want a radio that will let you run steering independently or linked together. Also, you will want to be able to run both motors together or independently to allow the front or rear to dig. Airtronics's™ RDS8000-FHSS stick radio is a very affordable 8-channel radio. It allows you to run the steering and ESCs independently or linked. The RDS8000 is based on an airplane radio, but Airtronics™ has replaced the ratcheting left gimbal with a spring-loaded unit so it will return to neutral automatically. Plus, it is a 2.4GHz radio so you never have to worry about being on someone's channel.
