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.

Some " More" build ?

1.Tkr5053a is flanged but on page 9 bag f it shows is on opposite side ? I followed f-4 picture. F-3 has flanged on opposite side if you go to back of manual & reference part #. weirdness??

2.Tkr5107 rubs on ackerman arm in one direction only? ( Dremel down )

3.Tkr5579 Shafts - ad orings? ( Orings come with Slash kit )

4.Tkr6018n - where does manual show when to screw these on? ( no biggie , figured id ask though)

5. StepL-3 Shock mounts inboard or outboard A - arm ? seems to look & fit better inboard IMO

Do any of you guys clean and re-lubricate your Tekno bearings or just replace them when needed? For those that clean them, what do you use to lubricate them? How do they come lubricated from the factory? I have some racers edge bearing oil but should I be using some black grease instead? Thanks in advance!!

I would just buy new ones, it's not worth the time to clean and re-lube them to me. I used to buy from Avid RC, they sell bearings for $1 each.

Who has a recommendation for diff weights for better turning on indoor high-bite?

Anyone tried going to more of a grease?

What setup is on the truck? I run mostly on med/high bite indoor and usually am taking steering out to get smooth laps, the truck has shit tons of steering so I'm thinking maybe something in your setup is not where it needs to be. What tires/compound you using most the time? Post a setup sheet, I'm sure plenty of people can offer up some things that may help . As for diffs, 10/10/7 and 7/7/5 seem to be the go to's for most locally but I do hear of people trying stuff heavier with success.

15/15/10 is the go to for most of the team. The truck is so light and small tire contact patch. Every time I try lighter I bail and go back to 15/15/10. Green springs all the way around. Play with sway bars a lot!

Truck is very predictable with that diff setup.

The flange direction can be changed as part of the tuning of the vehicle to move the link even further. It is also often shown on different sides of the vehicle.

2.Tkr5107 rubs on ackerman arm in one direction only? ( Dremel down )

This happens on some vehicles. I take a bit out just to be safe on my vehicles, as you can see here where I talk about doing so for the truggy.
+ YouTube Video
ERROR: If you can see this, then YouTube is down or you don't have Flash installed.


3.Tkr5579 Shafts - ad orings? ( Orings come with Slash kit )

Generally we don't add o rings here. If you can't stand the sound, o rings can help make it a little quieter. However, with the chassis flex that can happen in a large crash, leaving the full amount of space for the shaft to move can be the difference between a bent shaft or not.

4.Tkr6018n - where does manual show when to screw these on? ( no biggie , figured id ask though)

TKR6018 is the shock cap. These will be built different depending on how you're building the shocks, as we can use emulsion, vented, or non vented builds. You can see an example of a shock build by Ryan Lutz here.

5. StepL-3 Shock mounts inboard or outboard A - arm ? seems to look & fit better inboard IMO

If you mean inner or outer holes (from chassis center towards wheel), then this is a tuning option again. If you mean inside the rectangular opening vs on the outside edge of the arm, then it should always be in the rectangular opening so it is supported by the arm on both the front and back sides of the screw.

I usually run 7-7-5 associated diff fluid on outdoor hard packed medium traction watered track. 15-15-10 seems pretty thick but I hear people are liking the thicker setups with the 410.3. What benefits would I get by going with thicker diff fluids?

The shock mounts inside the arm. Here's a pic of the SCT410, the .3 mounts the shock the same way.

I used this setup for high bite. The tweak on this setup is pink fronts. I normally run green all around but this setup worked really well on high bite.

thicker fluids front and middle give 1. more 4x4 action in center diff. better acceleration 2. more on power steering. front diff 3. more traction off power entering corner. etc... The truck will pull it self around the corner. It will also smooth out the steering

Just about done with my build. What way should I build the shocks I know there's a few options and should I run the shock oil it came with or put heavier in?

Default shock package...

Has anyone tried this package:

Front
oil: 800 (65wt)
piston: 4x1.8 taper up
spring: Tekno pink
rebound: min.
vented

Rear
oil: 500 (40wt)
piston: 4x1.8 taper up
spring: Tekno pink
rebound: min.
vented

http://www.teknorc.com/tekno5/wp-con...Lewis_SDRC.pdf

Just looks odd on paper.
