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.

It actually wasn't violent at all. It was a step up to a 90* left turn and it landed on the pipe with the front tire and turned full left so maybe it was just to much stress? I was thinking it was a lower arm that broke but i was very surprised once I saw what broke. Even the other people with teknos never had seen it happen. Not trying to blame Tekno at all just surprised it was the much carnage. I had a lot worse crashes last week at thunder alley than today.

the hit was on the front tire ? then yeah , it broke in a strange way. I think most of the time the hingepin bend and dislocate itself. I had a handfull of landing directly on the nose and nothing broke so far but the hingepins bent and the arms stretched.
Maybe the aluminium part had a weakness

Yea the hit was on the front tire. Last week I did hit that left side a few times pretty hard so maybe the aluminum had some micro fractures/cracks and it finally gave. The hinge pin did bend too so who knows. Kind of a freak break if you so me ha. Oh well!!

You find the box setup to do pretty well?

i tried this today on a dry loose track, and it didn't handle like I was expecting... definitely wasn't stable for me.


i also broke my long battery strap today. >< ugh..

Yea it's decent for me. I don't have a track super close so I just adjust my driving rather than the car most of the time. (Either the track is super damn and almost muddy or bone dry) Like I said earlier my next thing to change will be the shock pistons and oil. At the track I run at is pretty easy to over jump and flat land a lot of the jumps with some pretty big acceleration bumps in corners too

The force that was applied to have broken that part AND snapped a hinge-pin in half is amazing. I have seen bent hinge pins over the years, but never a sheared off one! I honestly don't think without any of us having seen it that you will get many answers. As mentioned, the best thing is to check your droop settings and ensure the drivetrain is free.

That is not the hinge pin that is sheared, it is the long screw that holds the A block on and the two halves of the gearbox. Hinge pin is still in the arm.
Still a lot of carnage.

You are correct. Easier to see on my computer than when I was replying on the phone

I tried something similar to that before and I didn't like it. That's why I didn't try it again. So far nothing has felt better to me than Joe's Southern Nats setup from 2015. That's my starting point now no matter where I'm at. I rarely make changes too.

What setup change would help best to stop the car's rear end from getting loose when on the brakes or or letting off throttle after a high speed straight. It is not bad but is the only thing I feel I'm having issues with. Just switched to ams 7.0 setup,I'm thinking of limiting rear droop but also wondering about a diff fluid change
