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.

This depends on which ESC and radio you are running?

These are all servos I have ran with great results and relatively low price points. Savox seems to have brown out issues with Spectrum and low voltage esc's(6v internal BEC).

Hitec 7955TG
Protek 150T
Protek 170T chad bradley edition
Highest 2100
Savox 2273sg

been running the old faithful hitec 7955 for quite a while. Decided to try out the Savox 1270HV on my SCT410.3 and have been impressed. If old faithful finally bites the dust i'll give the Savox a try in buggy.

Thanks.

I can't speak for all the servos on the market, but what I've tried. Protek servos all the way. I have a 170s on 7.4 in my buggy and the 150's as my backup. You buy your servo on specs, find the one that falls in the range you want. I stuck with protek because its butter smooth. Smoothest servo I've ever used, NOT the cheapest. Buy a good servo and it only hurts once.

The highest servos. I'm kinda thinking they are rebadged proteks.....EXCEPT, you can get laser engraving on them. Servo with your name on it....thats hard to beat

It was a rocket, it also picked up the name "heat monster" because she was hot. I don't run any timing, you don't really need it. You also may be under geared. You should look at that. Running that motor wide open more then you think. Running that thing at red line makes a lot of heat because I don't think I've ever ran a pinion that small on my tekno's. Hope this helps

Very helpful, thanks. I've heard the SMC runs a little hot. But so far, I love this motor. I'll try taking it up a couple teeth this weekend and see what happens. But I'm pretty sure I'm going to try the new HW motors when they come out.

Regarding gearing of 1900kv motors. Start 18t, I've found it good almost everywhere. Various Tekno team drivers run 17-19. Generally, we don't run any timing, as it causes quite a bit of heat for very little gain on 4 pole motors. This has worked well for me on both medium and large sized tracks. If you're often wide open at full speed, gear up. If you're never getting to full speed, gear down.

Regarding the SMC 1900, the new ones will run slightly cooler (running change made to them).

For servos, I've been mostly happy with both of these in my full eBuggy:
ProTek 150t
Savox 2274

I'm in the process of switching to the ProTek 170s as I'm going to be putting one in both the EB48.3 and the new ET48.3 I'm building. Then all of my servos will all match at .07 for eBuggy, eTruggy, and 4wd SC (an Orion servo) when run on HV.

Highest is a servo OEM for other companies, not a copy of others. I've often considered picking a few of them up, customized, but that takes ordering direct from overseas (at least, it did when I looked into doing so at the beginning of the year).

Thanks for all the servo comments. I'm going with the tekin rx8 gen2 esc(I think that's what they are called). Im also deciding between the m12 or 4px

Make sure you buy yourself an external capacitor that attaches to your rx. You can either make your own or buy the Spektrum Glitch Buster. As far as radios, good choice on either. 4px rx's are a lot less pricey. My recommendation is to go to your lhs and hold both in your hand. Or ask some local drivers if you can hold theirs.

Probably the only company that keeps things the same price or as close as possible.

So I went with the Tekin RX8Gen2 1900KV and ESC thanks to the input on here and a deal I found on Ebay. I have the EB48.3 kit built, the servo, wheels, motor and ESC on the way. What else will I need besides lipo's to get er track ready? servo horn, correct gearing, etc?

Thanks

You really should base your decision on what feels better in your hand like portyansky said. They are both great remotes that are at the top of the game.

Thanks Eric
