We are very excited to introduce the NB48(TKR5300), a completely new 1/8th Nitro Buggy. Built on the hot-selling EB48 and SCT410 platform, it shares many parts already available around the world. But the real fun begins when you start to notice the details and optimizations we put into the vehicle. Like its electric counterpart, the EB48, this is not a conversion – it’s a ground up nitro design.
We started with the chassis and weight distribution. After computer analyzing 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.
We achieved ideal side-to-side weight by creating an all new 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 question was, “do we put the 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.
