Welcome to the EB48.3 Wiki


What option parts should I consider buying with a new kit?
None are required but we recommend the following:

Springs:
Low Grip Track:
TKR8772 – Yellow Low Frequency Rear Springs and TKR8762 – Grey Low Frequency Front Springs

Low to Medium Grip Track:
TKR8773 – Orange Low Frequency Rear Springs and TKR8763 – Black Low Frequency Front Springs

Medium to High Grip Track:
TKR8774 - Red Low Frequency Rear Springs and TKR8764 - Pink Low Frequency Front Springs

TKR5199B – HRC Rear Hubs (L/R, CV or uni, EB/NB/ET/NT48/48.3) - Improves stability of the rear on mid to corner exit. Able to be on power earlier on corner exit.

TKR6146 - CNC Delrin Shock Cartridge Set

TiNi Shock Shafts
-TKR6017T (front)
-TKR6061T (rear)

This car is very durable. Here are the spare parts that I recommend you keep on hand:
TKR5020 – Hinge Pins (inner, front/rear)
TKR6061T – Rear Shock Shafts w/ TiNi Coating and TKR6017T – Front Shock Shafts w/ TiNi Coating
TKR5286 – Front Suspension Arms and TKR5184 – Rear Suspension Arms
TKR5194 – Spindle Carriers
TKR6009 – Shock O-Ring and Bladder Set (for 2 shocks)

Tips and Tricks

List of Vehicle Setup Adjustments and Build Tips can be found here. There are several videos and articles detailing the building of shocks, diffs, camber links, etc.

Page 3 Step K-3
Put the screw in upside down so that the head of the screw is in the hex spot that's molded into the spindle. This will aid in clearance in full droop / full steering.

Page 12 Step I-2
Use no less than 4 shims on the steering spindle to limit steering throw. I actually just use one 2mm ball stud washer from my 10th scale stuff since each shim is .5mm.

Setup Sheets:
Setup sheets for all Tekno RC vehicles can be found here.

Warranty Policy:
Tekno RC is the only company in the industry that will give 50% off of parts if returned to them using the General Warranty return policy found on their website. The parts can be lightly used or completely abused, as long as the part is still being produced it's covered!

Piston Drills:
Some of our setups recommend using pistons that are enlarged. For instance 4x1.9 or 3x2.0. To drill the pistons we recommend the following:
GMK Supply Piston Drill Set
16PC Metric Bit Set Metric Sizes 2.00 to 3.00 MM.

Default Official Tekno RC EB48.3 Thread

Check back often for updates to the first post
TKR5005 – EB48.3 1/8th Competition Electric Buggy Kit
Since the release of the original EB48 in August of 2012, we have been continually improving our products. Over the years we have tested hundreds of parts, released dozens of meaningful options, and we have improved the overall setup of the EB48. The EB48.2 improved on the original vehicle and has enjoyed incredible success around the world. Now it’s time to introduce the EB48.3 – the new standard in the 1/8th Electric Buggy class.

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.

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. Maintenance is easier with the addition of the split center differential mount (TKR5260, TKR5263).

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.

No new body. Agreed on the old one and on the LFR. The JC Finnisher and the Proline Phanton are great choices....that stock body is unappealing. I really like the stock NT48 and ET48 bodies and was hoping for an updated EB body from Tekno.

Buggy looks good, look forward to seeing how the updates help the platform. Contrary to the two people above, I LOVE the stock body, its sleek and evil looking

Yes, truggy shocks. Although the .2 buggy rears are the same as the truggy fronts. So if one were upgrading their .2 buggy they would only need to get the truggy rears and put the .2 rears on the front. I hope that makes sense

EB48.3 is available for pre-order now direct from Tekno. I believe Fierce RC Solutions also has pre-orders up. Other sites/distributors/hobby shops will follow as soon as they can I'm sure. Contact your preferred dealer and inquire for the best possible info.
We're hoping to have an initial shipment landing in the 2nd week of July. A lot of spare parts are already here, just waiting for the kits before we set them live on the site.
