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

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

-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!

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.

Car went great this weekend,
BUT:
just some little, hard "Bumps" about 10cm high and 40cm wide, and the "nose down" was dramatic. Changed oil in the back to 300cst: a little bit better. Moved the upper mount of the suspension inward: not better, reduced the travel: the problem was amplified. Changed everything without the oil back and get 3. overall (just 5 competitors).

Planed my next changes:
Building some pistons 4x1,8, oil: more cst, building a "bump" for testing in the backyard.

You can see my car in this Youtube video: http://youtu.be/Yjx15m04iRU
I see that you moved your esc location to behind the battery. How did the truck handle with the esc in the stock location? Just a thought, maybe by moving 80 grams of weight that far back on the chassis is accentuating the rear chassis slap causing the truck to nose down. In my experience reducing droop and lowering the truck makes the problem worse, while increasing suspension travel will improve the flight characteristics of the truck.

For those of you that have been waiting for SMC race packs to come in, I have found an alternative.

I ran the VANT 7600 hard wired (bought from Promatch) and they ran the same/better as the race packs from SMC. My powerlab 6 shows IR in the 1.2-1.4 for both packs after 4-5 cycles. Brand new they where 1.8 and after few cycles/runs they got even better. Battery's where luke warm after a 7 min main with outside temp at 95. Deans plug was a tad warmer, but nothing like the unsoldering bullets I had on the old SMC packs. (Not an issues with SMC packs, just issue with using bullets that are worn out)

Very impressed right now with these VANT batteries. Hope this helps others that have been waiting for a year it seems for SMC race packs.

I also ran SMC packs quite a bit and out of frustration with their lack of availability and last pack puffed badly and too quickly imo, I tried out the Vant batteries. My first pack was a 2S 6500 75C/150C pack. A few things I just loved... first was that I could order the pack with an EC5 already soldered on and ready to go, second, the warranty they have says if the pack ever goes bad, you get half the value towards a replacement pack, think about that for a minute, that's pretty awesome. My second pack was the 2S 6500 100C/200C and I loved it just as much as the first, excellent performance and run times. Thirds pack I bought was for an EB48.3 and I got the 6500 4S 75C/150C, really great in the buggy, excellent overall experience. I will be buying only Vant batteries from now on unless something changes dramatically.

It's chassis slap, at least it was for me and some others... thicker oil, maybe slightly higher ride height and the issue is pretty much completely gone. A slower piston might help a bit too, but I just moved to 35wt associated oil in the rear and i'm happy, maybe lost a SMIDGE of rear handling, but not anything unmanageable.

Cool! I just ordered the exact same set up this weekend. This will be my first SCT and I can't wait to get it built

Are those the Factory Spec or Race Formula ? Pretty sure its the Factory Spec (Race Formala been out of stock for freaking for ever) and those are not even close to the Race Formula or these Vants.

Anyone running outdoors, especially on a large dry dusty outdoor track, check out the "Randy C" set up sheet on Tekno's website. I ran all my pills, my links & my shock Mounts the same as his set up. But I ran different shock oil & different springs (Black/Green). It's a really hooked up set up.

This past weekend I ran the Ryan Lutz ROAR ENats set up, and I liked the Randy C set up alot better. The Lutz set up was more geared for a smooth technical track like LCRC. It turned GREAT but my ass end was loose. I didn't like the shorter wheelbase either.

How was the handling impacted with the pink springs? Any help also with the nose down tendencies?

The 6x1.5 pistons make a big difference. If you want your truck to turn much better, get Black front springs. The greens are way too stiff. I ran Pink/Pink for awhile, they're not bad. The Black Fronts were one of the best changes I made along with the pistons.
