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.

I'd pick them over the 7200 for what I do. Only bad side of them is when they are dead they are dead. No limping them back to the driver stand, you gotta go get it.

I'm only putting in about 3000mah or so into my 7200's, so I think I can safely get away with a 6000....But...May have to step up to the 8000mah pro-match he pointed out to be safe.

That's them.. I noticed their site wouldn't load for me either..

Looks like you're getting a good set anyways... I have three I run and that keeps me going for as long as I need.. one goes in the charger when I'm done with the first and I have that third if the first isn't fully charged by the time I'm done...

If running on small-medium to large 1/8 scale tracks with 10 min mains, I personally wouldn't run anything under 7000mah. I've lost a couple of 6000mah where one cell dropped a little faster than the other, went under 3.3 volts and started to swell. I now run my cutoff at 7v total or 3.5v per cell depending on which way the esc settings are programmed.

I ran 2 pro-match batteries for a summer, they swelled like a balloon. They are a great battery but the case is thin. Just my experience.

That's a pretty good size track. If running 8 to 10 min, I would go with at least 7000mah. I personally run turnigy nanotech ultimate 7500mah in my mains.

The turnigy graphene is supposed to be better than the ultimates, but I've never run them. My 2 yr old ultimates are still going strong so I haven't had a need to purchase any.

The SPC racing 7200 packs are awesome. Bought two of them and they perform great. Also have 4 of their 5200's which also perform well. No reduction of performance at all after many discharge/charge cycles.

highest spc i see is 6000, and its out of stock anyway.

i need to order something from smc anyway to get a replacement 4s. just not sure between 2s 7200 60c or 2s 6000 100c, or just another 4s for my eb and a non-smc 2s.

i think they generally run 6-7min mains at my track, but i don't want to be screwed if they do a 10, and im not sure what the other local tracks run yet. the 6000mah 100c seemed good, but not if it won't last...

I thought spc made an 8000? I guess not. I don't see it. I thought I did. They do make a 7200. The decision os totally yours. Personally, I think 60c is plenty and I would go with 7200, 60C. Or turnigy graphene 7500 from hobbyking. Get it from a US store.

I run smc 6500 60c in 8 min mains. Any longer than that you will need the 7200

Most manufacturers don't like to make a pack above 7200, due to increased IR loads. The larger the cells, the more resistance. But this is negligible in my opinion and would always recommend getting a pack that has enough Mah to get the job done with reserve.
You may not see as high of burst ratings with the larger packs, but your not going to experience drop off over the race period, which equals consistency and we all know what that can do for a racer advantage.
Past poor solder joints or bad gearing, over discharge is the number one killer of any pack.
I will recommend checking out RC Juice for packs upto 8000mah. Jeremy McGuigan runs them and several other people I know do to without any issue what so ever. That guy is super fast at getting your orders out to and you won't find better customer service.
Another person I buy packs from 6500 or less is Mark from M&K Racing.
They are branded RCKING, but in reality they are SMC with a different sticker for outsource sales. I test a 2S pack from him that seen IR as low as .9 on one cell with the other at a 1.0 once broken in.
As stated by many by now, true C ratings are generally much lower than what they advertise and is mostly just BS.
70C has tested the same as my other 100C packs from different makes.
And that Graphine stuff is BS to. True nano tech graphine is so expensive it would cost roughly $1500 to make a pack with true sheet graphine. So don't buy into it. Look into it yourself if you don't believe what I'm telling you.

Guess I'll get the 7200, 60c.... Wasn't sure if 60c would be enough, but rather not dump during a race with the 6000 100c, hah...

Thanks Josh, I'll look into those for my next packs. I need to order from SMC this round to get my replacement sent out tho. But for future batts I'll check those out!

Hey no problem. SMC is solid packs. As long as you storage charge after a race and cycle your packs at least once every month or so, any good pack will last you a long time. I have packs running under 2.0 IR that are almost 2 years old with regular running.
Another thing worth mentioning,
I used to run bullet type packs, but I had a few melt the inner terminal from probably getting dirty and me not paying enough attention to clean them out.
That being said, all I run now are Traxxas connectors since they are the next best thing and haven't seen any problems like that since.
SMC claims the bullets are the lowest resistance due to the most surface contact you can get past direct soldering, but you have to keep them clean and bur free. I have seen some use a spark arrester to keep them from burring on initial contact.
