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.

As it sits for me I can make some 8 x 1.4s out of the stock pistons (seal and drill) but I am curious as I am running carpet if the 10 x 1.2s would be a better setup.

Thinking of putting the setup on my daughters car as much as possible and testing it that way
I just got the new eb48.4 emulsion caps today and i'm gonna rebuild the shocks for a race on Friday. I'll let ya know how the tapered down 8x1.4 pistons feel compated to the 10 * 1.2mms.

Once you get your turf setup dialed in, I'm might check it out at turf track in Cocoa bch



My sct isn't in this race..

My truck is not in that video... that was from 2 weeks ago.

Pistons... on my previous set-up I was running 6x1.5 piston with the taper up and green springs. Fronts 35w out on the arm and #4 on the tower. Rears 30w in on the arms and #3 on the tower. I was running 40/35 in the summer. Truck felt really planted on the track.

New set-up has the 8x1.4 pistons with the taper down and black fronts (35w), green rear (25w). Fronts out on the arms and #2 on the tower, Rears in on the arms and #1 on the tower... surprisingly, completely different shock set up and yet it feels the same on the track. Really hugs the track and feels planted.

About set-ups... It took me a long time to get my set-up where it felt good to me. I was questioning it a few weeks ago and let a couple of the fast guys drive my truck... I have never seen my truck go so fast around the track LOL. They answered my question of "how does it feel" with "your truck is hooked up... don't change a thing".
A friend has recently got back into the hobby with a used 410.3 and I gave him a copy of my old set up sheet with directions to follow ALL of the set-up... well, he has only made a couple of the changes and complained last night that his truck did not feel right... loose and erratic on the track... all I could tell him is he has to make all of the changes to make it work as one.

I think the same goes for this new set-up with the steering and the shocks and the sweep and the anti squat... you have to make all of them to make get the benefit.

And yes... we have a killer track here in TX... !!!

Default Setup

Do you think the new setup would work well for loose/loamy out door tracks. Unfortunately we dont have the type of indoor tracks the US has here in Australia.
I drove my tekno for thr first time this weekend after building and followed Randy Cathcarts set up for loose/ loamy. I also run the hrc rear hubs and 1/8 wheels. The truck handles superb and jumps awesome. I can hardly fault it. Im running a xr10 pro 160 amp esc and hobby king 2 pole 550, 5 turn. It flies...
Just wondering if this new set up would compare on out door loose tracks.

Cool looking forward to hearing how you like the caps.

I think the Jesse Munn setup is quite nice, a lot of the linkage setups are similar. Outside of the steering components and maybe the 10 x 1.2mm pistons I am seriously thinking of just putting it on my daughters truck and see, with maybe slight carpet changes but the big thing I am thinking that could matter a lot here would be in comparison to the Jesse Munn ones would be:

- Amount Toe (use the Munn setup or even less)
- Diffs from new standard

Last time working on another 4wd sct I really noticed a nice diff in traction issues going up on the diff fluid.

Also need to utilize some steering stops, I think that can help a lot too.

What pinion are you using and how are your motor temps? I have a spare Viper 4.5 550 2-pole motor that I want to try out so the gearing should be similar. Thanks.

Was about 158 using 17 tooth pinion, stock spur, fan and heat sink on motor. This was on a fairly warm day and about a 8 min run

Thank you. I have a Hobbywing 4000kv 4 pole also but want to try the 550 2-pole for smoothness and easier on electronics.

back when I was using a 1/10 speedo, the Speed Passion GT2.0 Pro the Hobbywing 4000KV 3656SD motor worked fine on it. Just had to play with the punch settings. The ESCs now should be better, so personally, I would think the same motor would work quite well these days.

Wish we had indoor tracks like that here!
4x4 sct is not popular here in Australia. In fact at my local clubs they dont run them as the excuse is either-
There is not enough interest or members with them.
They are too expensive to maintain and run and they dont want that to be the case for members. (Maybe if you own a losi or Ae)
Or the other is they wreck the tracks. (Its all 1/10 2wd and 4wd buggy here)
There is now enough of us with Teknos to start a 4x4 sct class. Hopefully they let us race them when we approach them at start of new race season

The big thing I see is that the 4x4 SCT is basically a light 1/8 buggy. So you need to keep that in mind relative to say landing carpet, etc. if it could damage the track. I don't know about astro though if its a concern at all.

To be honest if you guys are starting a 4x4 SCT class, my suggestion would be look into a common Kv rating you guys can agree on that can limit the amount of wear on tires you see. You may find that having a Kv rating that fits well as almost a spec speed could bring more people into the class.

We out here actually have guys, myself included, that start our kids on 4x4 SCTs do to the fact they can take a beating. We end up limiting the motor power basically via EPA and let them go at it. When I see that, it makes me wonder if 4x4 SCT could benefit from say a true spec motor. like say a 2200kv tp 2400kv motor or so on 2S.

My beast! Easy build. Awesome quality

Yeah they are definitely lighter than 1/8 buggies.
We will suggest we all be running 2s and no limitation on motor. Also no 1/8 size wheels which I currently run. The thing is a hoot to drive on 1/8 wheels!

Do you know if any other non sct bodies fit the sct410?

Here you go Cain.
Please remember this is a very high traction clay setup. I think this will work on turf as well.
