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.

Will shortening the front camber links give me more front steering. Still batteling some on power push. I can nail the throttle and get it to rotate but at half throttle it pushes allot. I removed the front sway bar but still want more steering.

Quote pulled from one of the many setup websites on the web.


A short link makes that the body doesn't roll as far, its tendency to roll drops off as it rolls. This can stabilize a car in bumps and curved sections.
It feels as is the car generates a little less grip.
I am guessing that what you are looking for is going to be made in multiple areas, not just a simple remove front swaybar and shorten camber links\change roll centers. I wish I could tell you exactly what it will take to get that initial turn-in on power you are looking for but too new to 1/8th scale buggy to nail it down. It took me the better part of two full days at the track and working through at least sixteen battery packs to get my buggy close to perfect. The website I linked above has an abridged outline of what each settings effects will be which should help you understand what areas to address and work on your next time at the track.

If I was to hazard a guess at some changes that would give what you are looking for would be-

Front Toe Out- Increases turn-in steering a lot. But can make the car wandery on the straights; Never use more than 2 degrees of front toe-out!

Angled Front Camber Links- Turn-in is very aggressive. The front feels as if it wants to roll less than the rear.

More inclined on the front shocks (inner holes upper outer holes on lower)- Steering feels very smooth. A little more mid-corner steering.

Softer Front Spring- The car has more steering, especially in the middle part and the exit of the corner. Front springs that are too soft can make the car hook and spin, and they can also make it react sluggishly.



All of this is just a snapshot of what is offered in that link I posted. With out knowing the track surface, your driving style, the best person to make the decisions on what to change is you. Go over one of the setup pages and start getting familiar with what each of the changes do, and remember, by adding to the front traction you are taking away some of the rear traction. it is always a sliding scale so find the balance you need to get fast lap times for your driving style. You should also spend some time understanding the diffs and how changing the oil viscosity changes on and off power steering. These buggies are a total kick in the butt, they are also pretty complicated little machines that require time to understand and get setup properly.

What does the rest of your setup look like? I found the stock setup to have some push. Switched to one of Lutz's setups with a couple of minor tweaks and it is dialed.

I have had a lot of luck getting more turn by shortening the front camber links on my eb48.2 and sct 410 I say try it if it doesn't give the desired effect change it back. Almost done with my eb48.3 build also only the shocks left. I am also waiting on my LFR Assassin body.

If you need more steering try the front uprights and spindles from the .2

The .3 have trailing spindles to make the car more stable. I switched to the .2 parts and the car turns better off power. The trailing spindle works great on high bite but low bite I like the v2 parts.

Need some advice in electronics setup... Will run HW150A + Xerun motor, always have the same problem when it's reveresed on the chassis... The car accelerates backwards, has 100% power on reverse, 20% power forward, etc... Need help with:

1. Motor rotation on the ESC settings: forward vs reversed?
2. Throttle control on the radio settings: normal vs reversed?
3. Binding the radio and setting up brake/throttle range - when should I do it, before or after properly setting no.1 and no.2?

Read the instructions for the esc.

I have motor rotation normal.

Throttle on radio is dependant on brand of radio. I think most are normal, futaba is reversed.

Set epa to 100% on f/r

Then calibrate esc after you do these settings.

I found in the long setting n the front link there was binding.
Found the Lutz set up to push at mid corner. I switched to the Bornhorst set up and love it so far.

I personally set it on the esc so everything else appears the same/normal. Then I set the ranges. So does the HW esc rotate the motor in opposite direction of a tekin esc?

If you have the field card or program card for the HW you need to change motor direction. Also check which direction your radio is setup for as well... "Normal" or "Rev"

Shortening the front link makes the car more stable. Sweepers, off-power, on power, etc. It will land better as well. We have been moving to a shorter front link lately and the results have been great.

Theoretically it gives you less initial steering but more on power steering. What we have found is less twitch and the rear follows the front better around and out of corners.

Start with the front link short (shortest on hub, shortest on tower, middle on tower). Tune the steering with the rear end:

thicker sway bar (more steering everywhere)
more rear toe (more entry steering)
less rear toe (more stability entering, but more steering out of the corner)
