This is the Tekno RC NB48 1/8 Competition Off-Road Nitro Buggy Kit. Built off of the EB48 and SCT410 platforms, the NB48 features a variety of details and optimizations that are unique. It shares many readily available Tekno parts already available around the world, and like its electric counterpart, the EB48, the NB48 is not a conversion – it’s a ground up nitro design. When you back this up with Tekno RC’s unparalleled customer service and community interaction, you have one of the most competitive and innovative buggies available.

Chassis & Weight Distribution

After computer analysis of dozens of different layouts it became clear that a lot of the current vehicles on the market are not optimized. Some are too heavy on the right side (rear diff output is offset too far). Others are more balanced but the engine and weight distribution aren’t as centralized (rear diff output is not offset enough), producing slower steering response in ‘U’ and ‘S’ sections. Tekno achieved ideal side-to-side weight balance by developing a 100% unique mid-offset rear bulkhead and ring gear. It moves the engine closer to the center without overloading the right side. It also minimizes drive angles and wear on the center dog bones. The drivetrain is as free as can be without sacrificing chassis layout and weight balance on the very narrow 4mm 7075 CNC hard anodized aluminum chassis.

The next dilemma was "weight forward or back?” How about both! The engine can be mounted in two positions, a front position and an 18mm offset rear position. Under most conditions, the motor forward produces the fastest cornering and subsequent lap times. In very bumpy or very loose conditions testing shows the rear engine position can be easier to drive.

The last challenge with weight distribution is how low it can be placed. Following a design cue from the EB48, Tekno created the radio tray and the right mudguard as one piece. This allowed the receiver battery to essentially sit on the chassis producing the lowest CG possible. The receiver sits right behind the battery and the throttle servo is mounted behind the receiver. Wiring is clean and easy with almost no exposed wires. Finishing off the radio tray are integrated mounts for the transponder, switch, and antenna. The entire radio tray/mud guard can be removed with only 6 screws making cleaning the NB48 an easy task.

Linkage & Brakes
The throttle and brake linkage setups were approached with precision and consistency in mind. The throttle is pulled by a CNC machined assembly riding on ball bearings. This costs more to produce, but a system so critical to the performance of a nitro vehicle should be perfect. The brakes were designed to be simple and effective. They are side-mounted on the center differential assembly and brake bias adjustments are a simple turn of the connecting turnbuckle. After testing various disc and brake pad material combinations, it was abundantly clear that a steel disc with semi-metallic brake pads is the best setup. Again, it costs more to produce, but who wants brakes that are inconsistent and fade on the 3rd lap of your main event?

Clutch
A 4 shoe clutch and clutch bell transmit power smoothly and efficiently. Access to the clutch shoes and springs are simple with no special tools required other than a hex driver. Large diameter inner and outer bearings means more time in between rebuilds and less bearing failure. The clutch bells are also compatible with most other 4 shoe clutch systems.

Fuel Tank
The fuel tank is a typical clunk style tank, but with some additional features to keep things running well and running clean. Raised sides on the outside of the tank helps keep fuel off the chassis. There is also an overflow fuel outlet that drains through the bottom of the chassis. We spent a lot of time choosing the right spring and seal for the tank. The result is a tank that runs virtually the same from fuel fill up to pit stop.

Steering & Suspension

The steering and suspension are direct carryovers from the EB48. Bulletproof suspension arms, silky smooth 16mm bore shocks, precision steering, and a ton of adjustments will keep you headed in the right direction. The differentials are light and extremely durable. They will provide consistent leak-free performance tank after tank.

Options in the Box
We also decided to include a host of performance parts that are usually options on most other cars. These include lightened aluminum pivot balls, steering posts, lightened gears and outdrives throughout, CNC tapered pistons, and super lightened offset wheel hubs. Dry weight is roughly 3260g depending on equipment installed.
