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.

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

What shock pistons are you guys using? Seems like the tekno ones aren't available. Was looking for 8x1.3 and 6x1.5

Get the blank pistons and drill them out to 8x1.4 If you can find the 8x1.3 conical you can drill those out but you would be better off drilling out a set of the blank flat pistons. Run 450/300 shock oils.

Has anyone tried different sized holes in the same piston? I had been using 8 X 1.3 and had no complaints. I've been trying 6 X 1.5 pistons lately and raised oil weight 5(AE) in both front and rear. No spring changes were made. It felt a little softer to me, and seems to offer less lift from jumps.

8 X 1.3
6 X 1.5
4 X 1.5 + 4 X 1.05
They each have roughly the same surface area. How do you think the 4X(1.5+1.05) would react in comparison to the other 2 pistons as far as pack, or anything else..

Hi everyone, I'm almost finished building my SCT 410.3 and it is looking great. This is my first SCT and I'm wondering how the performance of a Tekin 1850 kV on 4S would compare with the 4000+ kV motors people run on 2S? I don't want to deal with overheating issues that can occur on the lower voltage set ups. I've been busy reading this thread and I am about halfway through and I appreciate all the valuable information it contains. There is a couple of mentions about this motor within but not talking specifically about its performance. Kind wishes, ~Tom

I ran the 1850 in my EB48SL for a few seasons indoors and it was plenty fast and was very smooth, but it lacked the snap that a T8i1950 provided. With that said it should work fine in the SCT410.3, however 4s batteries will be an issue (illegal) if you decide to race.

I'm currently running the Tekin 4300Kv on 2s and have no issues with heat, 2s voltage does put more strain on the battery life though. If you get a good high Mah 2s battery you will be fine unless you are just looking to bash, then the 4s / 1850Kv set up is worth a shot.

Thanks for the information Eric! Actually no one has mentioned cell count where I race so I have my buggy on a 1400 kV 6S using old 30C batteries from about year 2012 which are still running strong. I have not asked for permission to use that set up, but rather if I ever get in trouble, I will seek forgiveness! Hoping for the same strategy with SCT. Just looking for average speed to keep up with the average racer but me using inexpensive medium C 4S batteries. ~Tom

I had the Tiken 4300HD which used to run hot. Then switched to the hobby wing 3660SD 4300KV G2. It runs way cooler. Both are ruining on 2S. Barely need a motor fan anymore indoors.

The Tekin Pro4 4300hd is a stout motor. I'm running the Tekin rx8 Gen3 also. Get good 2s Batteries and enjoy. Just gear it right and if you need a fan then do so, which I am. Currently running an 18t to knock down the torque.I feel this is as fast you need to run it.

The Tekin 4300 is a beast and drinks accordingly.
