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.

Ok, that makes sense as they have both ends with the washers floating at the opposite end that makes any mechanical changes. Thanks for that!

I have not looked up any actual setup sheets, what is typical washer count on the inside and outside for the steering arms?

Depends on the track. Lower bite most use less washers. But it depends on the steering feel you're trying to get.

Sounds good, like most vehicles this is going to be a track specific and driving style adjustment. I added one washer on both ends and left the other three under the ball. With a couple hours each night I have the chassis complete up to building the shocks, going along smoothly and looking good. You gotta love that in-line drive shaft setup, it just looks proper.

Being that I am at the shock build and this kit offers two different setups, I am curious what the advantages and disadvantages are to each type of shock build? What did most folks opt for, vented or emulsion build?

Acuallt there are 3 options. Emulsion, vented bladder and non vented bladder. I opted for vented bladder mainly because I find it easier to set rebound consistently between shocks. I know some of the other guys have tried emulsion I'm sure they will give their experiences.

In case anyone is thinking of trying it, the losi electric clutch fits perfect.

The newest carbon towers out are for the SCT410.3 & EB48SL which are different than the truggy towers on the EB48.3

You might be able to make it work with a different brand but I used losi. The Tekno clutch bells for the nitro car are the same style as losi but this is the only one I could find in an 18t.

Thanks for the info, curious how this system works on an electric car. Never seen anyone run one.

There are currently no plans to offer the towers in carbon fiber. Your best bet would be to email Xtreme Racing and request them to make some.

I used to run the Tekno version on my original eb48 and it worked great. Made the car easier to drive on low bite. Smooths out the low end punch. You can use different springs and shoes to tune it.

I am real curious the advantage to running the nitro style clutch on an electric buggy? Is it that the drive line is disengaged quickly to help rotate through tighter corners? Never even realized that was being done on the electric side of the industry.

The original Tekno traktion drive you could run as a nitro style clutch but you had to use mechanical brakes and 2nd servo. You could also configure it as a slipper, which is how the losi is made to work. Instead of the springs pulling the shoes in, they push them out in constant contact with the clutch bell. The harder the spring the harder they are pushed against the clutch bell and less slippage. Just smoothes out the buggy in acceleration and a little in braking. It's a nice tuning option to have.
