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.

I went softer in the rear and removed my rear brace, that helped with the kick out a lot.

Maybe I should've weighed my motor, esc, servo and rx. That would've given me a better idea of a balanced truck. But I'm sure they weigh more than 468 grams.
I am running Tekin RX8 (77g), T8 motor (311g), ProTek 130T servo (61g). The total is 449g. It should be under 470g plus the rx and wires. So I am running smaller batteries for better balance.

He runs a 27mm front ride height and his shock not was about on the middle of the threads... like I said I have to run nut all the way to bottom of threads to get 27mm! Does any one have a suggestion or clue why this is??
Thank you!
The springs that come with the kit are black. Most of us switched to Pinks. They are one step stiffer and 5mm longer. Put them on the car and never worry about it again

Here's the pic he posted

EB48.3
SMC6500
Tekin RX8
Tekin 1900KV

I don't think he had the wheels on, but that shouldn't affect the balance.

To do a back to back test would be too much work. You'll have to adjust ride height and possibly change out shock oil and springs to compensate for weight difference.

Plus I'm running a toro motor and it comes in at 411 grams!!!! Yikes!

450 grams with pinion gear and some wires

Small things to consider, servo horn, pinion gear, motor mount and transponder. Those would add maybe 50 grams or so? Just weighed out my 19t. It's 13 grams.

I have been running 7-7-5 front to rear associated diff oil. Track was smooth this spring and good tracking. Now our track is getting pretty bumpy and blown out and loose. Would I benefit from going lighter like 5-7-3 or 5-5-3 or are you guys having better luck with the heavier oils even on a rough track? Thanks!!

I am gonna try 5-5-3 this weekend on a low grip track now that my diffs are broken in . Buggy felt a little too locked in last weekend with switchblades and the southern nats setup . For some reason my buggy was flying much higher and farther than the losis and mugens over the triple which was a nice advantage.

We run 7-7-5 PT oils, which is considerably thinner than AE. I would try 5-5-3 AE before you do anything (or switch to PT )

Also make sure your pistons are taper up /\ not \/
If the track gets super blown out, switch to 3 hole pistons with 700 fr 750 rear

What diff oils do you like on a smoother track wtih more traction? Do you go up from 7-7-5 PT oil? Is there a big difference between taper up and taper down on pistons? I run them taper down to get more pack because we have one big jump where you bottom out and chassis slap pretty bad if you over shoot the landing. Thanks for the help!!
