This new Buggy Kit TKR5004 should be ideal for racing at our Local Ottawa tracks.  It's designed to run with Short Course 4x4 electronics 2s cell. 4s cell not needed.

At Tekno RC, we pride ourselves on listening to our customers and responding to popular  demand.  After releasing the original SCT410 4×4 SC truck, many people were ‘converting’ the SC platform into a 1/8th scale buggy that utilized the lighter drivetrain and suspension components of the SC.  This led us to release a conversion kit to accomplish the task easier.  The acceptance in the marketplace was immediate, as many customers could now run a 1/8th scale buggy using 2s lipo batteries and Pro4 motors and ESC’s.  Furthermore, they could run on some tracks that didn’t allow for ‘full weight’ 4s lipo powered beasts.

Then we thought, “why not make it even easier for our customers to get what they want and offer a full blown SL kit?”  Enter the EB48SL.  Tekno RC was the first company to offer a purpose built 1/8th electric buggy when it hit the scene a few years ago.  And now we’ve done it again with the first purpose built ‘Super Light’ 1/8th electric buggy.  The EB48SL is built on the new SCT410.3 platform and shares ~95% parts compatibility with it.  All of the new improvements and features put into the SCT410.3 are all present in the EB48SL, along with a couple others specifically for the buggy.

The EB48SL represents a new and emerging class that is far more accessible to more people just starting out in the class.  Batteries, motors, and parts are less expensive than their full weight 1/8th cousins.  The kit itself is also an undeniable value and is backed by the best customer service in the industry.

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 a 1/8th scale tread with much less weight and a touch less power results in maximum traction and corner speed.  The EB48 is known for it’s steering, jumping ability, and efficiency and the SL continues this legacy.

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 we say ‘thank you’ to our customers, by providing maximum performance at a reasonable price.

THIS IS NOT A REPLACEMENT FOR THE EB48.3.  THIS IS A NEW 1/8th BUGGY KIT FOR AN EMERGING RACE CLASS.

This is pretty cool actually, a purpose built Lite eBuggy made for tracks like ours at SAR.  I'd be interested to see it run vs. the Pro8.  Wonder who'll be next to put out a kit like this, made for indoors on smaller tracks for 2S.  Outside of a full blown 1/8 motor and 4S, it still runs heavy duty stuff though, like the 1/8 ESC, and Pro4 Hd 550 motors are hardly 1/10 like electronics at all, so jumping up to this class is still an investment.  Looks like big fun though!

If you were planning on transferring your 10th electronics to this then yes your right it is an investment since you can't do that.

But if you're deciding between buying a 10th 4wd buggy and this Super light scale buggy, the electronics are $35 in difference from what I see on amain.com

ESC & Motor for 10th 4wd buggy:
Tekin RSX Gen2 Sensored Brushless ESC/Motor Combo (6.5T) - $329

ESC & Motor for Super Light:
Tekin RX8 Gen 2 $204.99 plus Tekin Pro4 HD 4-Pole Brushless 550 Motor w/5mm Shaft (4,300kV) $159 = $365

Even the prices of the buggy are about the same:
XB4 2015 - $439
B44.3 - $379
D413 - $429

EB48SL - $439

You could of seen it on Canada Day at SAR.   :P

It drove so nice during practice, I like the 2 cell nimble feeling.   So much steering wow.   Even Tony Tang had his SCT410.3 out, we said he was loving it too.

I have a write up I'm working on that I will post soon.

I'm taking over this thread since I now own this Super Light! ;D

I saw this buggy run last summer at GFX in Orleans and thought it looked really good out on the track and I liked the idea of a light weight 1/8th eBuggy.  Like I saw last summer, I'll run the proven Tekin 1850kv motor and an SMC 3300mah 4S battery.  Side note - the SMC batteries, while 4S, are about the same size as a touring sedan 2S stick pack, so it is small by industry standards but still manages to last for the length of a 6 minute main - and I've seen it go longer!  SMC also make a slim 4500mah 4S pack, which I'll consider getting next.

In the mean time I have torn this ebuggy down to its nuts and bolts.  I gave her a nice warm soapy bath with warm water and Simple Green, a good scrub and a liberal spray of WD40 to shine her up nice!  I am currently in the middle of the rebuild and working out an initial set up.  I gotta get the JConcepts S1 body to the paint shop (Bodywerks) and am waiting on a few parts to arrive from Great Hobbies - ya, local parts support!  Stay tuned for more.
