Team Associated has released two new 1/10-scale 4WD electric buggy kits: the RC10B84.1 and RC10B84.1D Team Kits. The updated B84.1 platform arrives with a long list of revisions, and the manufacturer’s stated goal is straightforward: improve durability and increase speed.
The RC10B84.1 Team Kit is priced at $639, while the RC10B84.1D Team Kit comes in at $619. The new kits are part of the RC10B84 family, the platform Team Associated launched as the successor to its World Championship-winning B74. The D version is paired with a setup intended for dirt-track racing.
What’s New on the RC10B84.1
The revision work starts in the drivetrain, where molded height-adjustable gearboxes front and rear are designed for maximum drivetrain efficiency. Under the car, the chassis now uses a wide tongue layout for improved durability, with V2 side rails shaped to fit it. Up front, wide A and B mounts team with a 73mm gull wing front arm, a carbon fiber front shock tower, and a molded front shock tower cover built for the new arm geometry. V2 steering posts and bellcranks round out the front-end changes, while long HD differential outdrives and 66mm rear CVA bones strengthen the rear drivetrain. New 0.7mm shims for the A and D mounts are also part of the update.
Race-Tuned Details
Around those revisions, the long-arm suspension geometry is meant to improve grip and predictability in all conditions. Optimized steering bellcranks and rack target bump steer control at all ride heights. In the box, racers get standard and HRC (High Roll Center) rear hubs, plus insert-adjustable caster blocks with 0, +/-1, and +/-2 degree inserts.
Weight-bias tuning runs through forward and rear motor positions and a highly adjustable battery holder with thumb tabs. The platform sits on a 2.5mm tapered 7075-T6 aluminum chassis with 10 degrees of kickup and an improved departure angle, and a split top deck that Team Associated says optimizes chassis flex. Upper and lower chassis bracing front and rear lets drivers fine-tune flex characteristics.
Completing the package are a decoupled slipper clutch, aluminum center-mounted servo mount, 13mm big-bore shocks, front and rear shock tower covers, 3.5mm turnbuckles and ballcups, a low-profile body, and a 7-inch rear wing with two mount heights.
Dirt-Focused D and Classic Flavor
The D kit, according to the official feature list, adds a +2 rear gearbox for high-grip conditions and includes molded ring and pinion gears, fitting its dirt-focused setup. Team Associated has also shown a Classic version of the RC10B84D, with an RC10 Classic-inspired livery, premium composite plastics, and aluminum parts. The Classic variant repeats the same molded height-adjustable gearboxes, long-arm suspension geometry, and 13mm big-bore shocks.
Track-Proven Setup
Team Associated’s official RC10B84 page includes setup sheets from drivers including Chad Due, Jermaine Robinson, Brady Carrico, Marcus Kaerup, Davide Ongaro, Alexander Landen, Matthew Gonzales, Aydin Horne, Davey Batta, and Spencer Rivkin. Their event notes cover the IFMAR World Championships, ROAR 1:10 Dirt Off-Road Nationals, JConcepts events, and the Nordic Championship. The listed conditions span indoor black carpet at medium grip, indoor dirt at high grip, and outdoor dirt with low-to-medium grip.
What You’ll Need to Finish
Both versions ship as unassembled race kits. An instruction manual is included. To finish the car you’ll need a motor, pinion gear, electronic speed control, servo, transmitter and receiver, tires, wheels, polycarbonate body paint, battery and charger, plus the usual tools and silicone fluids. The AMain Hobbies listing notes a 7.4V-7.6V 2S LiPo in shorty dimensions as the power source.
