'Short Course Trucks' are currently some of the most popular vehicles for RC racing. There are several reasons for the popularity of these designs. First of all, they replicate the full-scale short course racers that compete at outdoor tracks and stadiums all over the US. Perhaps a more significant aspect is that short course trucks are exciting to drive. Many short course designs are close adaptations of the top-tier 2-wheel-drive and 4-wheel-drive buggies that are at the cutting edge of RC off-road design.
RC short course trucks are not only for racing; they are also well suited to bashing. Their wide tires let them run on a variety of surfaces. It also helps that they have meaty bumpers and full-fendered bodies covering the tires. These help to keep the truck right side up when knocking into things like curbs and other vehicles.
My first short course truck is the Tower Hobbies Cutback. Although it has some race-ready features (brushless motor, full ball bearings), the Cutback is primarily meant for bashing. That works out great for me since I haven't raced in years. That being said, the Cutback might be competitive at some local-level tracks.
This truck arrives fully assembled, with a painted body and a 2-channel 2.4GHz pistol-grip radio. I had to provide four AA batteries for the transmitter and onboard batteries to run the truck. I'll talk more about those batteries in a bit.
This is a four-wheel-drive truck with three gear-type differentials, one on the front end, one on the rear end, and one on the drive shaft. The core of the chassis is a 3mm-thick aluminum plate. Attached to this plate is a nylon tub that houses the electronics and drive components. Other parts such as the suspension arms, bumpers and spur gear are made of molded nylon as well. Interestingly, all of these plastic parts are covered by a 1-year warranty with free replacement.
