Welcome to the SCT410.3 Wiki!

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

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

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)

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.

did a quick go through of what I got here and for used it looks pretty good for what counts. Will give it the full teardown treatment, chassis of course has the good used look but I figured that would be the case lol.


As for carpet setup, in general the raising the rear link helped with freeing up the rear end on rotation. For the tight tracks here it really helped a lot.

One thing I noticed is that the astro turf setup runs pretty stiff sway bars. I ordered them to try the setup out as here you can traction roll unsauced clay slicks on the carpet.

I also did a test fit of the xray "wundersprings" progressive greys that were used on the durango desc10 I had as recommended by a guy in europe who modified his vehicle specifically for carpet, including a custom graphite chassis.

Anyway, I figure if they work well with alittle more roll on the desc10 stock, they could work well on the tekno and be worth a try. I put them on and they fit the cups well, little more room from the shock body so need to confirm they dont' hit anything suspension wise but I think they will be fine. Another benefit is that they are very short. This will allow some really low ride heights for sure.

One way to find what gear to start with is find the gearing someone else is using at your track, punch in the numbers into a speed calculator, then, use your gear and target the same theorectical top speed. Watch temps, but that can get you into the ball park.

so, what is the current word on chassis to use if you plan to replace it? stick with stock SCT410.3 or spring for what, the eb48.3 one, the M2C, etc?

Default Tekno sct 410.3 and 160amp xr10pro

Hi guys. Just purchased one of these fine kits. My first sct (i run 1/10 buggies) and was impressed after driving a friends one.
Can anyone tell me is it okay to run a hobbywing xr10 pro 160 amp esc running 2s with a 2 pole 550 motor. I think its 3150kv. Its then king turnigy sct motor.

Cheers

well, I can say this. Back when the first SCT410 came out we ran the Speed Passion GT2.0 Pro with the 2 Pole 550 and 4 Pole 540 and "545" motors without issue. This is basically the hobbywing ESC V2.0 or whatever.

I would personally think the XR10 pro is even more powerful, however, I would say they have an ESC right now that will do the job and is made specifically for it, and is cheaper too the XR8 SCT Pro Esc. I would go with that.

For motor, if you don't have to use say a 540 4 pole / 550 2 pole, The Hobbywing 4000Kv 3656SD is a great motor and I really like the Maclan 4150kv motor (I use this now).


Alright so I did my teardowns, the vehicle I picked up used came with a lot of parts and some cut springs. Other than the usual checking of bearings, etc. What do you guys look for as to determining to get a new chassis?

I'm pretty sure you can, but I would check this thread first Hobbywing xr10 pro , Page 9, post 126 of that thread should help.

Ok thanks guys. I just want to use the 160amp esc from my 1/10 buggy without having to buy a new one.

Also another few quick questions.
Am i better off setting up shocks emulsion or vented?
Outdoor Track surface will vary from hard packed smooth to rough/bumpy. Also jumps involved.

Lastly we dont have a class of racing for 4wd sct locally here because there is not enough numbers. However there are now probably enough of us now to start one. I am going to run 1/8 wheels on mine. For you guys that race- do they allow the use of 1/8 wheels in the same race as those using 1/10 wheels?
Does it handle/jump better with 1/10 wheels or 1/8 wheels?

Cheers
Mark

Some tracks will allow the 1/8th scale wheels. If I'm directing a race I won't. The 1/8 wheels definitely handle better. There is a lot less sidewall flex. You can get a short course tire to feel almost like an 1/8 tire but you have to be a wizard with the tire glue.

If you decide though to keep it more SCT style, just get some 17mm SCT wheels. Work great on the desc10 I had.

I have both kinds of DE SCT 17mm wheels and I love them. I did try my EB tires on it before, but for whatever reason I didn't care for the setup I was using with SCT wheels, with EB wheels.. I didnt really adjust anything I don't think. So ride heith and stuff was probably all jacked.

Anyone off the top of their head know what the track width of the 410.3 is?
