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

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.

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.

However , now i'm looking to fit the 1/8 eb 48.3 part# tkr 5166 bumper. Which is much lower profile . Will it fit ? Starting to think this is due to wheels being to small for this rig..
Great point Jimmy and I have a fix. I noticed when I put my new bumper on today I was digging the front end in everywhere I went! my old setup had the front too low.. well, my old setup also had the old broken bumper that had the entire bottom segment removed.

Tomorrow i'm going to cut the bottom part off, there was no issue with bumper robustness even w/o that bottom part, and to be honest it just bends the center bolt anyway.

Thanks for finding that out! I should have realized it today. yea, sct tires are too small but that's the game.

Yep, 8 minute mains for 4x4 SC. I wasn't at that race last summer so I'm not sure who's who, but last weekend most people were running Teknos. There were a few Losi's and (I think) a Durango in the mix too but the Tekno is definitely the truck of choice.

I'm sure hundreds have because that is what the EB48SL is.
The TKR5570-17 is all you need. It comes with the stub axles and the set screw.
Makes it too wide though for current SCT width rules.

Which rules to go by?

SCT same as 1/10 electric off road truck?

As per Roar page 50 1/10 electric off road truck
section 8.7.2 maximum width is 13" . stock is 11-5/8".

7/7/5 is where I would start. If the track get loose then try limiting your steering epa to lessen the over steer.

Thanks Lowe's. I'll give it a try. Any tips of shock fluid? Looks like the truck has the stock pistons.

Also, I'm in the process of tearing the truck down and I noticed that the front-center driveshaft is worn in a couple of places. In one spot, it looks like it was rubbing on one of the braces and is probably out of balance now.

Has anyone else ever seen this? Is there a way to keep it from happening again in the future?

We started out 10f , 7c & 5r but rear tires were still breaking loose on hard acceleration on any surface. On loose stuff the rear started actually coming around on straights.We moved to 15f,10c & 10r. This seems pretty good on indoor high bite with primes & just ok outdoors . Outdoors I might move to 20f 15c 15r.

TKR5570-17 puts the hex's way too wide. Tires won't fit under a body let alone taking into consideration ROAR rules. 1/8 buggies are wider than SCT and that is what these and the 48SL and these hex's were built for.
If you want to go 17mm there are only two options, M2C conversions or the Traxxas 17m hex conversion. I have done the M2C and kept breaking axles and have recently purchased the 48SL stub axels and Traxxas 17mm hex's to try.
This has been well documented and discuss on the original SCT410 thread.

Sure thing, happy to help.
I use the DE Racing Borrego wheels-link below- that are designed for short course tires- so my wheels aren't larger. I think the overall diameter of SC tires is close to e-buggy tires so I don't think that there will be much difference in gear ratio.
But the Borrego wheels are more like buggy wheels in that they are dish style so I think they are stiffer offering better steering precision and grip. I think they let the tires do their job better. I also like the security of 17mm hex-much less likely to strip than 12mm. I know most don't have a problem stripping 12mm hex, but I have a few times. I think SCT should be 17mm across the board- one thing that Team Durango did right with their latest truck.
I am no way qualified to say with certainty if any of the above is true, but that's my story and I'm sticking to it.

the 17mm DE wheels are really good so if you do 17mm you will really like those.

Didn't know M2C conversion had axles breaking. Is this mainly on the older cars or on the new sct410.3 one?

Im shopping for a taller over all Tire for outdoor rough stuff. These low dimension tires cause Chassis face plant all to often. Chasing shock adjustments here is just chasing your tale & throwing $ at an issue for nothing ,IMO. The thing is Tire manufactures dont give demensions on there website. Or atleast I cant find it. The tallest tire ive tried is 4.35's. Which works fair but is still short . Any help finding a taller tire , med comp & pin'ed would be appreciated..

This happens to my truck, too. Driveshaft was bend (maybe after a very bad landing: Nose down...) The shaft was rubbing at the front brace channel and causing vibrations. I just bend it back carfully and sanded the burr a little bit, it is still working fine now (after one year, learning to jump and land and about 20 race weekends). Next step is my carbon driveshaft.

It was original M4 axles on SCT 410. M5 axles may not be a problem.
