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.

Go over your car and see how different you are compared to it. This setup works amazingly well for me and everyone of my friends who has tried it.

Also keep in mind that the team setups use PT Racing Oils, not AE or TLR. They are significantly thinner. close to 2k thinner on diff fluids. So 7-7-5 PT is closer to 5-5-3 AE.
Are the pistons with this set up tapered with flat side up?

I posted this on the Tekin thread but didn't get much help , I'm using the Rx 8 gen 2 combo in my EB 48.3. Today at the track everything seemed to work as intended when the car was on it wheels goin around the track. But when I flipped it over and I had to walk out there to flip it over, I noticed a few times the wheels would start to turn on there own. The last time it happened it was like someone gave it a serious throttle punch and it wouldn't stop until I used the radio to stop the wheels. ive used the buggy for about 7 other times with no problem. Spektrum receiver and radio with glitch buster. Radio calibration was done, push control is off.
Any thoughts ?

Not intentionally bashing on them, but this would be the first thing I looked into.....just saying. I had nothing but trouble out of the Spektrum I used for a while, and have seen too many others with similar stories.

Are you sure of that? Kit instructions are taper up and I haven't heard of many people running the other way.

I know no one running taper up personally. I've never even tried it

*edit* as I said, I can admit when I'm wrong!

Talked to Joe and he runs Taper up /_\ in all conditions unless it's very high bite or really smooth.

Default diff oils

Currently running 7,7,5 southern nats. If I'm looking to lock down the rear a bit off power, and I mean just a touch. Would going up in the center and the rear help or hurt?
I realize it might create a whip effect or drift on heavy throttle, but I'm developing a controlled finger pretty quickly. I like the way the front feels lots of off power steering and a tad of mid push is making it really easy to drive so I wasn't planning on changes there. Any ideas

When you say taper up you mean the piston looking like this? /---\ Taper pointed toward the top of the shock.
