Tekno RC Announces EB48.2

Aug 20, 2013 No Comments by

No one saw it coming when Tekno RC, then best-known for making electric conversions for most popular nitro vehicles, released the EB48 – after all, it was the first ground-up design categorized solely as an electric 1/8-scale buggy. The car sent waves through the industry and even landed on the cover of the October 2012 issue of RC Car Action! After a year of experience racing the EB48 against the best that the rest of the industry has to offer, Tekno RC revamped their brilliant buggy with a heavy dose of new parts to create version 2: a faster, lighter, and stronger kit.


Press release from Tekno RC:

Tekno RC’s presence in the 1/8th E-buggy class has been steadily growing since the release of the EB48 in August of 2012. Now we are introducing an updated EB48.2 buggy that is not only more competitive, but also represents the best value in the marketplace. Tekno RC has improved performance and durability without increasing the price of the kit.

The list of improvements on the EB48.2 starts with our XT suspension arms (TKR5030XT, TKR5036XT) as standard equipment which improves durability tremendously. We have included the +1.5 degree rear toe plate (TKR5013B) along with a new 0.5 degree offset insert to go along with the 1.0 and 0.0 offset inserts (TKR5021). New shock cartridges and shock bushings (TKR6008) improve handling consistency and reduce shaft deflection.

The differentials have been overhauled with new cross-pins and internal gears (TKR5149, TKR5150, as featured on the SCT410) as well as new straight cut CNC diff ring and pinion gears (TKR5151, TKR5152). The new gears are quieter, smoother and more efficient than previous gears and feature lightweight cutouts to reduce rotating mass. Lightened differential outdrives (TKR5112X, TKR5114X) are used throughout. The lightened aluminum center driveshaft (TKR5077) is now standard as well. A lighter drivetrain results in faster acceleration, higher top speed, and reduced wear. Our new angled rear gearbox (TKR5016B) and larger bearings (TKRBB05134) round out the driveline improvements. The new gearbox reduces wear and increases efficiency by minimizing the drive angles.

Up front the EB48.2 features a new HD servo saver spring (TKR5101X) helps to keep you pointing in the right direction. Lightened steering posts (TKR5102A) as well as lightened suspension sleeves (TKR5054A, TKR5055A) help reduce weight without any sacrifice in durability. Aluminum hard anodized pivot balls are used throughout (TKR5049A, TKR5052A, TKR5053A, TKR5058A, TKR5079A) to reduce weight. A more durable servo horn has also been included.

Combine all of this with an improved out-of-the-box setup and you have the best 1/8th Electric Buggy on the market. The EB48.2 raises the bar once again!

About the author

Associate Editor Since receiving my first hobby-grade RC car as a holiday present from my father nearly 20 years ago, I've been fortunate enough to meet more people and experience more opportunities through the adventures I've had in the RC industry than I would've ever imagined. I've done it all - from working at a hobby shop, to being a factory sponsored racer, to working for some of the biggest brands in the industry. I've enjoyed each and every one of the dozens of kits I've built, hundreds of events I've attended, and thousands of laps that I've logged at race tracks around the world, and my passion is to share those experiences with other hobbyists so that they may find fulfillment in their own RC careers.
