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

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.

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!

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

I run a 15 and sometimes 16. The 4700 is a great motor that can handle a load without qualm in my experience.
The trick to lowering temp is to run cap packs to help with the load ripple.

How would you compare the HW 4700 to the Pro4 HD4300 for this truck?

Thanks Kremzeek and Josh L, I've started out with a 15t and will see how it goes. I bought a used sct pro esc and a new hw4700, I'm replacing a castle 3800 system (which actually was for my kids so it worked ok) and I can tell just by running the hw on the bench that it is a totally different animal

I'm going to have to try to the cap pack thing with mine. I think I have an extra one laying around.

I run a 16t pinion on mine everywhere, but also a bit hefty of current limit on the rx8 (I need to update it and play with the new torque limit). This reduces wheel spin and helps keep temps down, while letting me pull most buggies (electric and nitro) down the straight, yet is smooth and consistent indoors on tighter tracks too. I don't make my turns with the rear hanging out and spinning though, so if you do that, expect more heat than I get. No fans on the motor though, just the normal ESC fan always on for me.

Temps vary a LOT based on driving style, ESC, ESC settings, and track conditions/layout, so your 15t that you settled on is a good start, but I would also have a 16 with you when going to a large track to see which you like better. I found that going down to 15t for me made it run hotter, but again, results will vary.

justpoet, the whole electric scene is new to me, i don't know anything about adusting the current limit or many of the other esc adjustments. I ran my first electric race (sct and ebuggy) last night and won the sct class and finished second in ebuggy/nitrobuggy (mostly do to great tekno vehicles, small turnout, and a lot of luck). I did adjust the punch to give it a little more snap, and actually ended up going to a 14t pinion do to track having several tight 180's, but will do some more testing with different pinions. I seem to have went from having a nosedive issue (only on Large 8th scale jumps) to a nose up issue, I think do to getting use to the extra power of the hw4700 compared to the castle 3800.I even adjusted brake to 100%, either way the 410.3 and the eb48.3 performed well above expectations and learn something new every time out.

I have own both the Tekin Pro4 4600, Tekin Pro4 4300 HD and the HW 4700.
The question was on the HW4700 and Tekin 4300 though.


In my opinion, the Tekin 4300 is the best motor if you are running stock set-up without lightening the truck as it will not overheat on a bigger, outdoor track as easily. For indoor racing, I honestly think the HW4700 is just as good or slightly better since the Tekno SCT410.3 needs a slight weight correction with the right rear and left front being the heaviest corners when using the Tekin 4300. For indoor racing, I still use the Tekin 4300 because I like the E-Buggy like power on the bottom while still having more top as well. I almost always use an 18t pinion as it gives me more air control with the throttle. I have never temped higher than 140*F even outdoors. With the HW4700, I would not use higher than a 16 ever and I have never used more than a 15t in races. If I were to go back to the HW, I would run between a 13t to a 15t. I prefer a higher pinion not due to speed but I think it takes a little "YANK" out of the truck and as stated before, it gives you more air control. You can always turn your radio down if needed. I run on an indoor track with a 90' straight.

Anyone know of a good place for setups for a short track like this? All the setup sheets on teknorc.com are for large tracks. Dont need a exact setup, just a good place to start and work from there.

Default Long Wear Practice Tires in Medium

What long wear tires do you guys recommend for the truck? On my eb48.3 at my track I use aka impact or Ibeam mediums for practice and super soft impact or X4 proline holeshots for racing.

Having trouble finding the medium wear on the impacts for the short course so open for any comparable suggestions.

If you are open to it, give Proline Blockades a look.

Proline Stunners if you can find them have a bigger pin height so may be good too.

Panther Boa Soft wear well and stick to about anything. The super soft Boa's are really sticky, but they do wear on abrasive tracks
These are very under rated tires, trust me!

just durango now. But have a fond place for tekno. 4x4 SCT has great turn out at one track here so get to battle it out with them. Lots of fun.

Good to know. I ended up buying a new EB48.3 /Tekin1900 instead of hooking my Losi SCTe up with my 4300. So keeping the 4300 in my Tekno and not getting a HW4700 for my extra truck.
