Welcome to the SCT410.3 Wiki!

7.26.17 - BB
In order to run the recommended team setup, you need the following optional parts:
TKR6106 Orange LF Springs
TKR6114 Green LF Springs
TKR6018 composite shock caps (built to emulsion) OR TKR8072 Aluminum Emulsion Shock caps
TKR8027 Shock Stand Offs
TKR6051 8x1.3 pistons(drilled to 1.4mm)
TKR8104 .4 bellcranks
TKR8100 .4 ackerman
TKR5545B HRC Hubs
You also need the Aluminum C Block (others can stay composite)

What option parts should I consider buying with a new kit?
None are required but we recommend the following:

TKR5161 V2 Adjustable Hinge Pin Brace A block, 7075 CNC, EB/NB/ET/NT/SCT) - Helps to improve durability on hard crashes.

TKR5163 V2 Adjustable Hinge Pin Brace C block, 7075 CNC, EB/NB/ET/NT/SCT) - Helps to improve durability on hard crashes.

TKR5545B HRC Rear Hubs (L/R, CV or uni, SCT.3/SL) - Improves stability of the rear on mid to corner exit. Allows harder acceleration on corner exit.

TKR6146 - CNC Delrin Shock Cartridge Set

TiNi Shock Shafts
-TKR6004T (front)
-TKR6017T (rear)


What spare parts should I keep on hand?
TKR5020 Hinge Pins (inner, front/rear)
TKR5516 Front Suspension Arms and TKR5515 Rear Suspension Arms
TKR5542 Spindle Carriers - TKR5541B Spindles
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.

Setup Sheets:
Setup sheets for all Tekno RC vehicles can be found here. Please be sure to try our recommended setup. It works very well on most tracks.

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.

you will want one on this vehicle. seems to be common to snap the plastic ones.

It is possible to run some of the cheaper horns you just have to raise the mounting mount on the steering arm to compensate. Or if you don't want to do that, just buy the appropriate tekno or similar servo horn.

My plastic one stripped after 3 track days. I don't know anyone that didn't strip theirs or just replace it with aluminum right away.

4wd SC is a pretty big load on the servo. You'll need an aluminum horn at some point. For some it's right away, others a few weeks. It's a good investment since it is a liability to finishing races.

Does anyone know if you need to sand the servo saver to get it to seat properly similar to the ET48?

I do not have a truggy--but I did not do any sanding on my servo saver. Make sure the posts seat into the slots on the chassis b4 screwing them in & you should be fine.

A lot of guys are just switching the stock pistons out for 6x 1.6 or 6x 1.5 s and running something like 35/30 for oil, and running the rest of the stock setup. That's probably the best place to start

Thanks for the info. Looking forward to trying out the new geometry.

Get a good 2.0mm and 2.5mm driver so you can chuck it into a cordless drill. I use a hudy set but I am sure the mip ones are good to. Just go slow and don't bottom the screw out with the drill. Always hand finish threads.

What exactly on the shocks are you having issues assembling? It took me awhile when I first starting running the Tekno cars to find the best way (at least, in my opinion) to build them

I hopefully will have a video up in about a week with my methods for completely rebuilding as well as just refilling shocks.

So if I install the aluminium wheel hexes (TKR5571A) what wheels will fit the truck, SCTE ones?

Okay almost done build. What a smooth easy build.
Okay first let me say I have built many many cars and trucks, but want to verify what to do before I drill shock caps.
Per the instructions to build vented bladder shocks it says to drill 2 holes in each cap.
First hole is where the threads are to allow oil to bleed out when tightening the cap, but no mention of where to drill second hole.
If it is where bleeder screw where hole is drilled to do emulsion style, after build do you put screw into this hole?
I prefer bladder style shocks and want to build it this way, just a little confused.
