Welcome to the SCT410.3 Wiki!

In order to run the recommended team setup, you need the following optional parts:

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.

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

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.

I do have a touch of rebound in the shocks and I'm sure I can get a few more turns on the shock ends so maybe that's all I need, we will see. Thanks

Spring change from stock green front/black rear to avoid nosediving? Not looking for perfection, but have read spring changes can help dramatically. thx

I ended up putting AE 35wt oil in the rear shocks and changed nothing else and the nose diving is reduced DRAMATICALLY... i also find just swapping to a little thicker oil hasn't killed my handling in the really loose stuff my track is famous for. I'm afraid a stiffer spring will screw up my handling, but I bet that would help as well, but for now, I feel 100% better in the jumps.

For me, the rear springs were too long to get the ride height where I wanted it, and was having nose down,endo issues. The fix was yellow FRONT springs and 40w for the rear shocks, stock set up in the front.

Helpful gentlemen at Tekno support was adamant the 410.3 stock setup was ideal to minimize nosediving. He mentioned the problem people have is with the build. Told me to lower the droop and go up 5 oil weight... sounds simple. hope it works.

Did You cut your tires pins? At least 2 lines of the outside of the front tires and 1 line outside in the back. For very high grip track we use additional tire glue at the outer side of the front tires. So the car could slip sidewas, if it is rolling up.

Default Lightweigth .3

Solved the nose down problem with small motor can (450 size, -100g, light controller in the back left , -60g and shorty lipo-100g. Car is about 2650g without body. The first race (Clay, getting dry and dusty) was much better than the others before, but need more practice. Next test will be on astro turf.

What exactly is wrong with it? In reality, the new truck is not a ton different from the old truck with included hop ups and improved suspension geometry. Let us know what you think is wrong and we should be able to help. Don't throw your money away. It's still the best 4x4 short course truck on the market by a long shot.

Did You tried to reduce suspension travel by using the droop screws?

What is the main difference between using the 6x1.5 pistons vs 10x1.2 pistons? How much droop should I person drop down for running on high bite carpet?
