Tekno RC NB48.3 1/8 Competition Off-Road Nitro Buggy Kit


SKU: TKR5304 Category:


This is the Tekno RC NB48.3 1/8 Scale Competition Off-Road Nitro Buggy Kit. Following the success that started in 2013, Tekno RC has updated the NB48 with the .3 version offering drivers a faster, nimbler, easier to drive buggy, while incorporating forward thinking to break the mold of what a nitro buggy is supposed to be.

Tekno RC started with the suspension and completely redesigned the geometry. The design aimed to improve big jump landings while at the same time improve small bump handling and consistency. To achieve this, longer shocks have been fitted to increase suspension travel, as well as updated towers (TKR5268, TKR5269), designed to optimize shock angles. Revised upper camber link positions on both the front and rear shock tower provide setup options that improve driveability and traction in all conditions. An updated piston was designed specifically for the longer shocks (TKR6159) to adjust the compression/rebound characteristics. The lower arms (TKR5184, TKR5286) feature updated shock mounting locations. Clamping spring perches (TKR6140) and updated shock boots (TKR6144, TKR6145) are included to keep the shocks clean, smooth, and trouble free. They also included the left and right handed shock mounting screws (TKR1240) to ensure you never lose a shock during operation.

The chassis has evolved as well (TKR5303). The EB48 and NB48 proved that moving weight forward results in better cornering so Tekno eliminated the rear engine configuration from the NB48.3 and concentrated on optimizing the handling and flex characteristics of the front engine layout. This improved the gear mesh between the clutch bell and updated 46T spur gear (TKR5119) and also helped to calm the rear of the car.

Another area that received an update was the braking. Larger, fully CNC machined, hardened, and ground discs (TKR5345B) replace the old parts. Improved semi-metallic brake pads (TKR5314B) are now separated by springs (TKR5368) to ensure the brakes are only engaged when you want them to be. The biggest change made to the brakes however, is with the linkage (TKR5336B). This updated brake system was designed for better consistency and easier brake bias adjustments.

Updated rear hubs (TKR5199) allow the option of using the stock CV axles or the upcoming optional universal driveshafts. Tekno now also offer the rear hubs in aluminum as an option (TKR5199A). At the front of the vehicle are updated trailing steering spindles (TKR5193) and spindle carriers (TKR5194).  The trailing components vastly improve high speed bump handling in addition to smoothing out the steering response. The vehicle initiates turns more predictably and finishes corners better than ever before. Larger bearings are now fitted to the front spindles for improved durability. The spindles will also accommodate the upcoming universal driveshafts.

The V2 hinge pin braces (TKR5161, TKR5162, TKR5163, TKR5164, TKR5165) have found their way into the NB48.3 kit. They provide more adjustability than ever before. For example, changing the roll centers at the hinge pin is now an easy task and allows you to set up the vehicle for any conditions.  Front arm sweep, kickup, rear anti-squat, and rear toe are all adjustable. A revised chassis was designed to increase clearance for the many V2 hinge pin positions.

Tekno’s low profile wing mount (TKR5181) is included to lower the CG of the whole vehicle. A revised front bumper (TKR5166) increases front ground clearance. Straight camber link rod ends (TKR5187) were produced to improve consistency in corners.

Finally, the box setup has been tuned by some of the best drivers in the world to give customers a vehicle that they can confidently drive in most conditions. With the extensive list of adjustments and improvements, it is easier than ever to tune the vehicle to your driving style and track conditions.
