    Dirt Oval Traxxas Bandit Project While the perceived upper echelons of full-size dirt oval racing may be sprint cars or late models, a huge amount of grassroots racing is done by regular Joes wheeling Street Stocks. All across America, drivers spend their time and money transforming Camaros and Monte Carlos into fender-rubbing, dirt-slinging, V8-powered race machines. This is real racing. And, as it often goes, the way things work in full-size racing is how things work in RC.

    While some race carbon fiber-equipped, high-tech and expensive sprint cars and late models, others get dirty and up and personal with street stocks built out of old buggies. This gritty style of racing is just too cool to pass up, so I decided to build my own street stock ride. My platform of choice was the Traxxas Bandit. It shares other parts such as the same chassis as the Rustler and the same shock towers seen on the entire stable.

    Like the other models, over the years, to keep it from getting long in the tooth, Traxxas has updated it. Body, graphics and wheels got a modern look along the way. Metal gears replaced plastic transmission gears and the transmission now rides on ball bearings. A much better slipper clutch was also incorporated. The Bandit has grown up, but it is still basically the same buggy it was way back in In addition to the obvious body and tire changes, I made improvements to the suspension and drivetrain.

    I rather offset the battery, but those are the rules. Know before you go. Now, all of that said, I knew the rules where I planned to race specifically said no aluminum suspension arms or shock towers. Okay, good. I went with graphite shock towers. At one point, the local street stock class was limited exclusively to Team Associated B4 buggies and the rules stated only stock or RPM parts. It was a little fuzzy as to whether the graphite towers were allowed under the new rules, but with the class now allowing such high tech and high dollar buggies such at the TLR 22 5.

    Put me where I belong. I might be a dope, but nitrous is a bit worse than graphite towers. I did, however, make some changes to be able to mount a full-fender street stock body on a buggy. I mounted this upside down and added universal body posts mounts from Parma. This takes care of front body support and offers some additional protection.

    These aluminum 12mm shocks are ridiculously nice. They are precision machined and high quality. The 3. The caps feature bleeder screws, so properly bleeding and matching the shocks is easy. I filled the shocks with 30 wt. The one exception was the right front shock, which I filled with 40 wt. At 4 mm of glorious carbon fiber laminate, these things really dress up the Bandit. These will also fit the Traxxas Slash, Rustler and Stampede. In addition to looking completely trick, the Xtreme towers provide a whole lot more tuning options than the stock towers.

    The Xtreme Racing front shock tower provides five inner camber link mounting points and 12 upper shock mount locations. The rear tower has four inner camber link mount options and 16 upper shock mounting locations. These towers worked perfectly on the Bandit, but are wide enough to accommodate the wider stance found on the Slash and Rustler.

    The rear tower also features an aluminum adapting mount and both towers include shock mounting hardware. Between the competition on the track and occasional brushes with the outside wall, dirt oval racing is definitely a contact sport. RPM offers the front arms in blue and black and the rear arms in black. The Bandit, like its stablemates, uses screw-in hinge pins.

    The drawback of this design is as the suspension cycles up and down, the movement actually unthreads the hinge pins. This problem gets worse with use and requires constant maintenance. And, in addition to being secured with a locknut, the hinge pins are hardened steel for durability and wear resistance. This time it was their aftermarket transmission case made for the Magnum You can read a review here.

    The main benefit, arguably, is the 3 mm thick T6 aluminum motor plate. This helps with motor cooling and is far superior at holding the motor in position compared to the stock plastic motor mount. The real secret weapon, however, is the fact that RPM went with separate suspension arm mounts. This is a huge advantage for dirt oval because it allows you to adjust rear toe differently on each side. Of course, I could run identical toe on both sides, as well.

    The stock cover has a hole for clearance around the drive output. The RPM case fixes this problem. Be aware that the depending on the inner camber link mount locations you use, you may not have enough room for any gear cover. Did you know that the internal nickname at General Motors for the Camaro was the Panther? Some tracks have approved body lists, so check first. Matt Bury Digital Designed cut the custom vinyl numbers and lettering. If you want custom vinyl, I highly suggest hooking up with Digital Designed.

    As cliche as it sounds, from mild to wild, Digital Designed has you covered. Can you identify where I got the paint scheme? These tires not only look scale, but are made to perform. The Angel Block tires feature a rounded side tread that, according to Pro-Line, is designed for a consistent slide that will not catch ruts.

    The inside of the front tires are smooth while the rear tires have reinforcement bars to help the carcass hold its shape when accelerating and cornering.

    Is it harder to design a tire that must factor in both performance and appearance? What challenges did you encounter? The challenge to get a tire to work in RC is the tread spacing can only be spaced out so much before you start losing that scale look. We believe we hit that right balance with the Hoosier tires. What advantages does closed-cell offer open-cell inserts and how do the two materials impact handling? GG: The closed-cell inserts give the tire better sidewall support and it lasts longer than open-cell inserts.

    Dirt oval racing generates a lot more sidewall force, so that support is key in maintaining a consistent run. RC Truck Stop: Do you recommend venting the wheel or tire on Hoosiers and how big and how many holes? GG: We generally put two holes in the wheel and two holes on the tire opposite of each other just offset from the top center of the tire. Both around 2 mm wide. For wheels, I decided to switch from the pin-driven Traxxas wheels to hex-driven Pro-Line Veleocity 2.

    To be able to use hex wheels, I installed Slash front axles and used Traxxas black hexes on all four corners. I will also use Traxxas gray hexes on front wheels when I want to increase wheel spacing, which impacts handling. Lately, this company has been a go-to source for bashers, but, make no mistake, SMC is well known in oval racing.

    This is a high-quality pack offered at a reasonable price. My transmitter of choice for this build is the Hitec Lynx 4S 2. Some of my favorite features are the built-in antenna and model memory. My guilty pleasure on this radio is the ability to upload and program in. I did swap out the standard RTR Traxxas servo for a more high performance servo. While hardcore racers know it, many people may not realize that Hitec makes some of the absolute best servos in the business.

    At 6 volts the transit time is 0. Word of warning when using a low-profile servo such as the DBWP, it does require some trimming of the servo mount to get the servo to clear without the servo lead getting pinched. My first run with the dirt oval Street Stock Bandit was just a shakedown, but it also happened to be a trophy race.

    On one hand, I just wanted to make sure my best-guess baseline setup was close enough to make it around the track and, on the other hand, I wanted the car to be as close to competitive as possible. Okay, so I knew the tires would work. Second, I was looking for excessive body roll. Next, I try to eyeball where my gearing is at. I should mention that these three things—traction, body roll and gearing—are all interrelated. How so? Well, if the car wants to spin, I will probably try a gearing change before a tire change.

    This is especially true if the car is on-power loose. Anyway, my initial goal is to just get the car race-worthy. I want the car to turn with as little steering input as possible. This trophy race was a night race, under the lights, and consisted of two four-minute qualifiers and a five-minute main.

    All qualifiers and mains featured rolling starts.
