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 didn't know about the turnbuckles. Thanks for clearing that up.

It's different geometry that alters the ackermann. The best way to describe it is that it makes the steering feel smoother. It transitions better on and off power as well as beginning, middle, and end of a turn. The old geometry was pretty aggressive and once you started the turn the car could really start to come around on you. So if you had an increasing radius turn you often time would be turning too much, then counter steering to correct, then turning more to get back in line, etc. The new geometry fixes that. You can still get a lot of steering out of the car, but it is so much more usable than before. I really like the new steering setup in my SC truck, really helps calm it down.

And I don't think I had to cut my turnbuckles down on my SC, I'll have to double check that though.

Ok, you'll have to cut the sc turnbuckles down as well. 3mm per side, which is what the buggy should be as well (I updated my earlier post).

Thanks for the response, I know all the other new option parts have been very beneficial, I'll definitely give the steering components a try!

that sounds exactly like the problem I felt on my SCT410.1 version on the larger track with its sweeper, towards the end would want to come around on you more than I liked. Indoor tight track though was fine.

Would you say the change is better all around or are there times you want the old steering setup?

Am I correct that its these turnbuckles you need to trim, the steering ones:

KR5123 has M4 threading on the ends, is 56mm long, and can be used with TKR1103 (4mm) for easy adjustability.

If so is this the lunsford option to get:

LUNS1450 4 x 50mm Titanium Turnbuckle (1/pkg)
http://www.lunsfordracing.com/mm5/me...egory_Code=4MM

Looks like associated has an option too:

Better pretty much everywhere.

The lunsford ones look like they have more thread so I'd prefer those, but basically any 4mm threaded 50mm long turnbuckle should work.

So is it worth doing all these changes or just waiting on the .4?

Lately, it's been tough trying to keep up with all the changes (hrc hubs, springs, etc.) And I'm running 4 teknos. I guess it's probably only been about $120 + shipping, lol, total, but it's still extra loot. If the .4 is going to be released soon, I'm wondering if it's worth it. I guess some of that too depends on how many more changes are coming. It would be nice to know so I could decide what to do. I might change one of the buggies and see if I like the feel.

The separation is in the suspension front arms (Tkr5286), with the arm's support tkr5161 and tkr5162, is a lot of separation, your cars have this separation too?, is normaly?

Is this a recommended update for the truggies as well?

Does anyone know what body offers the most amount of room for a large battery and the most room in general?
