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.

ahh yes he brought up a good point that I always assume everyone knows. Make sure you are setting the End Points / Travel correctly. You don't want the servo to keep trying to crank away when it's physically limited.

So if I go with a 1268 savox
I would need to run it at 7.4 bec to get the 300+ torque correct? Sorry for the noob questions.

Yup that's correct. I run it in 6.0v for 10th scale. Again, it's nice to just use one servo in all cars.

We are pleased to announce a complete line of Low Frequency (LF) springs that will further improve the handling of your NB/EB48.3 vehicles. Our new spring design improves traction by reducing chassis oscillation on rough track surfaces and large jump landings. Overall stability of the vehicle is improved, providing better forward grip, increased corner speed and quicker lap times.

With additional coils as well as a larger wire diameter, the new LF springs feature a bronze gunmetal finish with a color indicator for easy spring identification. The springs fit all variants of the NB48 and EB48 vehicles and include two springs per package.

Click here for more info.

If it feels like the rear is locked down too much (not rotating), recommend adding a little camber to the rear. Should help free it to rotate in corners. The new HRC hubs do add more grip to the rear and adding camber helps it rotate and also be more forgiving in the bumps.

Good deal. That will be my next change. Right now I'm sitting at 2 deg. I'm going to play with my driving style (buggy rotates pretty good when carrying speed). It's the slow corners (180s) that get me from time to time if I had to slow down too much (mistake, traffic, bad line, etc).

No first hand exp. Doing this, but de makes 17mm wheels, you'd need side guards, and bodymounts, if the mounts don't fit on the eb towers you'd need to fabricate or switch out towers.
If the 17mm offsets to wide. It's gunna get pricey as you'll need nwmew cvd

Could also try shorter wheelbase to help rotation, correct Matt?

With that being said, it SHOULD be enough. But if you're rough on the car, landing often on one wheel, taking big tumbles, etc... you could blow through one.

The other thing is make sure your servo saver is actually working, nothing is bound. Also it's NOT an HV servo, so you can only run it at 6 volts.

This is actually the servo I had in my 10th scale stuff and 4wd sct prior to switching to the 1268.
So I got the 1268 in today and the wire is not long enuff? ??

You need a servo extender, can pick up a 3" at your LHS for $2-3
