When we decided to release a nitro buggy in November of 2013, a lot of people were scratching their heads. What does Tekno RC, a company known for electric innovation, know about nitro? But we were up to the challenge and NB48’s started popping up at tracks across the world. The experience has been invaluable. We learned a lot and we have listened to our customers. The NB48.3 is faster, nimbler, easier to drive and it incorporates some forward thinking that breaks the mold of what a nitro buggy is supposed to be.
We started with the suspension and completely redesigned the geometry. The new design aimed to improve big jump landings while at the same time improve small bump handling and consistency. Longer shocks have been fitted to increase suspension travel and new towers (TKR5268, TKR5269) were 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. A new piston was designed specifically for the longer shocks (TKR6159) to adjust the compression/rebound characteristics. The lower arms (TKR5184, TKR5286) feature new shock mounting locations. Clamping spring perches (TKR6140) and new shock boots (TKR6144, TKR6145) are included to keep the shocks clean, smooth, and trouble free. We 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 we 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 new 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). An all new brake system was designed for better consistency and easier brake bias adjustments.
New rear hubs (TKR5199) allow the option of using the stock CV axles or the upcoming universal driveshafts. We now also offer the rear hubs in aluminum as an option (TKR5199A). At the front of the vehicle are new 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 accommdate the upcoming universal driveshafts.
The V2 hinge pin braces (TKR5161, TKR5162, TKR5163, TKR5164, TKR5165) have found their way into the new 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.
Our 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 our 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.
