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.

Don't worry about posting here, glad to help, but I would still tighten your servo saver back up .
Ok, cool! I just know some forums aren't as tolerant!

Ok, I thought that the bolt included with the horn must be the pinch bolt, but the way it's designed doesn't actually allow it to "pinch" the horn together. The bolt bottoms out on the horn as it's not recessed like the 23T and 24T versions. I've stripped 2 aluminum servo horns at this point so I'll tighten the saver back up and see if the 3rd time's a charm.

Thanks for the help!

Someone please explain this to me like I'm a six year old , cause I don't understand.

And what method do you guys use to measure toe?
This only applies if you have the new steering system: TKR8100, TKR8104 and TKR1403. The new ackerman bar (TKR8100) is longer than the original ackerman bar. To compensate, either the original steering links (TKR5123) need to be cut down to 50mm (3mm from each side) or buy a set of 50mm turnbuckles with 4mm thread. Associated, Lunsford and Kyosho makes a turnbuckle this size. Seems like there was one more on Amain.

Here are some 4x50 Turnbuckles that I found to make it easy on everyone.

https://www.amainhobbies.com/kyosho-...oif489/p492606

https://www.amainhobbies.com/team-as...c89526/p144553


question about these though with regards to mounting. The Tekno turnbuckles have a notch that goes on the left side of the buggy. There are no notches on these, how would they be orientated on the truck?

Looking at this new recommended setup sheet that was posted a few days ago and I have a question.

The notes mention using the TKR6051 which is the 8x1.3 conical but it says to drill them to 1.4. Why wouldn't you just use the TKR6053 that is already 8x1.4? Is there something else different between them?

I would make sure the thread is going the same way.

Please no. I can't stand how quickly they slop out.

I am assuming the Tekno material would be better, just whatever the hub is made of placed there instead. Then, just replacing the insert versus the whole hub.

I don't think they make those anymore.

Only real change was to lower ride height to 19mm for indoor. Highly recommend this to be used as a base setup as it's easy to drive and jumps well.
So what ride height did you use outdoors?

I had 8x1.3m pistons in my tool box & used mini metric bit to make 8x1.4mm pistons.



I used the new recommended setup with 10x1.2mm pistons and older steering parts this weekend; my sct was very easy to drive.
