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 TKR8702 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.

Yeah, I took it to the track that day and it worked awesome.. Had power for days and ran at room temperature.. Very impressed for $50.00

videos good thanks handy tip, what i meant was that trying to fit 10awg wire into the U channel on the tekin esc gold posts is tricky, the u channel is too narrow where as if you stick with 12awg its much easier and slots in nicely :-)

Flite-test has the perfect demo on this, but it also works with a large wire against a solid post to, just a slightly different initial approach.

Tin the wire then use a pair of smooth jaw pliers and squeeze the tinned wire into a rectangular shape. This will make it easier to fit in the slots on the solder posts. I had to do it this way with 12 gauge wire with my RX8.

Hey guys. My kit will be coming in within the next few days. Im chrious to know about any immediate upgrades to the kit you may suggest. Also, curious to know a good starting point for fluids in the diffs and shocks.

Order the CNC Delrin conical shock pistons, and spacers. They are white. It makes all the difference in the world!

Guys, I just ran my 410.3 for the first time! Rx8 Gen2 , Pro4 4600KV , I used a 17t pinion. On 2S. My goodness! Ridiculous power! My motor was barely warm? I didn't even run the ESC fan either. Normal for a pro4 to run so cool? I squeezed about 18 minutes on a 5000 MAH battery. Driving fairly easy, just trying not break it all in!

Not a single problem, accept alot of power! So much fun! I don't think I would ever need a Pro4HD...


I'm excited over this Tekin combo, inside this Tekno truck. Temps were at 100F

That's exactly what I do to. I also tin more open wire than I need to so I can cut it down to the right length before I shape it for the terminal.
Don't even need shrink wrap really, but I do it anyways just so it looks nice.

I do the same thing to the wires before soldering them to the motor. Makes for a really clean look.

Thank man! I ordered a 15t pinion and ill be running the same motor. Would you suggest the 17 for an outdoor 8th scale track? I planned on having 15-17 anyway but ive got a 15 on the way with the kit.

I bought an Aluminum A block brace per justpoet's recommendation when I built my kit.

I've got combination of 13 tooth, 15 tooth, and 17 tooth pinion.

The 17 is a blast, good for a large track, alot of speed. Definitely closer to 50mph range.

The Tekin Pro4 is a awesome motor. I was impressed. Everybody is buying the bigger HD 550 version which is fine. But seems it might be to much.

I've got a Trinity Zombie 545 motor 4 pole in 4,850KV I am excited to try. They are suppose to pull harder then the pro4 HD motors. Well see!

Good luck with the kit.

Keep a real close eye on the temp. of that motor. I found I couldn't fit a small enough pinion to get the heat down enough to run long races. A fan helped

I just purchased this one, I heard that the first batch ran really hot! I spoke to A guy at Trinity and he said mine is a newer model and was just built a few months ago based on its S/N , and keep temps under 180f.

My first big solder job. Not to pretty, but it's strong when melted with flux. And it's getting a good connection.

i finally got a chance to drive this more, i find there is so much steering, and if find that i roll over a lot when i turn.

i have stock springs in the front and pink in the rear, but otherwise it is box stock with box stock setup. i am not sure where to even begin to figure out where to start. When i had the stock shocks in the back it was too soft and would not hold it up enough on acceleration.

any help with this is appreciated
