This is the Tekno RC EB48.3SL SuperLight 4WD Competition 1/8 Electric Buggy Kit. Tekno RC was the first company to offer a purpose built 1/8th electric buggy. The EB48.3SL is a totally unique platform that was developed for the emerging 1/8 Light Buggy class, and is the first purpose built ‘Super Light’ 1/8th electric buggy. The EB48.3SL represents an emerging class that is far more accessible to the average racer. Batteries, motors, and parts are less expensive than the full weight 1/8th cousins. The kit itself is also an undeniable value, backed by Tekno's incredible customer service.

The EB48.3SL is built on the SCT410.3 platform and shares 95% parts compatibility with it. All of the improvements and features put into the SCT410.3 are all present on the EB48SL, along with a couple others specifically for the buggy. But enough of that – how does it perform on the track? ‘Easy to drive fast’ would be the best way to describe the SL. Full traction patch of an 1/8th scale buggy tire, with much less weight and a touch less power results in maximum traction and corner speed. Lightened differentials, lightened driveline, and lightened aluminum parts are standard and used throughout. 16mm bore, aluminum threaded body, long travel shocks are standard. Updated SCT410.3 suspension geometry is standard. Split center diff mount and lightened chassis are standard. This is how Tekno says ‘thank you’ to their customers, by providing maximum performance at a reasonable price.

Tekno RC EB48.3SL SuperLight 4WD Competition 1/8 Electric Buggy Kit
I have been watching 8th scale buggy for years thinking man these guys are good. After building this car the first time I ran it was a race, I didn't even get to take a lap. I immediately felt like I was wrong for all of these years, 8th scale buggy is just much easier to drive. The other option is that THIS buggy is easy to drive, it really is. I am running with a Hobbywing xr8 sct and HW 4300 kv 550 motor with 2s 6000mah 70c battery 15t pinion. 4 weekends in I will tell you it is not the fastest buggy on the track by any means but man its smooth and glued. It feels a little slow when driving it, however I am turning some good lap times and finishing races top 5 every time. Recently I cruised from 9th to 4th with little problem. Point is this buggy is competitive and easy to drive. Protips: Buy a set of diff shims tkr1222 as they are tough to get right the first time and need to be replaced after breaking the buggy in. Cut some vent holes for your esc and motor, it gets hot in there. If you follow the instructions when assembling your steering assembly you will end up with like 15 degrees of toe out. Just build the steering tie rods last if you can. The piston nuts when building the shocks were tough for me, get a shock shaft tool. Don't tell anyone you are using 2s if you can help it, it will trigger people.

Fast on 2s
Solid, Durable, quality build.
Serious Steering
Terrific Traction
Easy to drive
Looks distinguished on the track
Super tight tolerances and fit of build

Does not instruct you to vent the body or how
Some measurements for linkage are inaccurate
extra diff shims not included
Build requires tremendous hand strength and or the proper tools. I have pretty strong hands and I felt like some people would not be able to thread tie rod ends, assemble shock shafts and maybe even the diff screws.

Hope this helps.

By far the sweetest ride out there. Built like a tank. Light as a feather. Running Tekin RX8 ESC, Tekin 4300kv motor combo with a LiPo 2s. I love this buggy!
