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.

just got this truck.what is the best front spring setup for running as a e light? The stock green springs are so long I cant get the front low enough,Stock pistons and oil setup. I tried green losi fronts,they are just a bit shorter and stiffer than the green tekno,will this work well?
Whats the best setup for a indoor track with alot of very tight hair pins,high bite pretty smooth clay,50 ft straightaway.

Not exactly.. the .3 sct uses the plastic cross pins but other than that pretty sure it's a match. (ya as noted by Matt, outputs are different)

Diff outputs are smaller on the SC/SL than the full weight. Also the SC/SL come with plastic cross pins.

Answered by the others, but I'll expound upon it.

All of the Tekno vehicles share the same diff cup and internal diff gears.
All electrics share the same spur gears.
All electrics besides the truggy also share all the ring gears.
SC and SL share outdrives and the 8th scales all share a different outdrive.

Change your droop, this will lock down the arm to where you want it to stop for travel. (103-105 range is usually good) use some calipers to measure top screw to bottom screw.

I'd go w/ a 6 hole piston 1.5, seems to be the most liked. 40wt front, 35wt rear

Seems like there was a setup on Tekno website for the type of track you are talking about...Shaun Brown or Daniel Lewis setup...maybe. Maybe one of those would be a good starting point.

For you guys that haven't try'd it do yourself a favor and give it a go, its easy to play with and makes a big difference. Going to do it on my Eb48SL as well.

Thanks for the tips on the shocks,the droop is a bit more than that on the current setup,where do you like to run the shocks on the towers and arms with this droop?
I dont see how these function as a steering stop, maybe this one isnt installed right,but the wheels seem to have a inconsistent stopping point when set with the radio steering end points? at full steering the inside wheel in the turn has to much slop in it,I cant get it to hold tight?

Put a screw in the hole on the inside of the steering block and space it with washers if necessary, I run mine without washers just screwed out the same on each side to keep the inside steering stop consistent.

I'm currently running the high bite (Shawn Brown) setup off the website and it's works great.

Put washers under the small button head screw inside the steering arm.

Great pic for showing where to add the washers, I'm going to add it to the first post.
Also, we pretty much run 4 washers at every track we go to, we've run up to 6.

I couldn't figure where it was you were talking about until you posted the pic. I looked in the manual and it says nothing about these screws, not to put them in and they're not on the parts list of screws. I did however write a note on the page that I had 2 extra 6mm button head screws. I am assuming they are the ones to use? Is it necessary to use washers or can I just back them out an equal amount of turns?
