Bob B 8/10/17 - Should I start with the kit setup?
The kit setup is a great place to start. One other option that many of us start with is Joe's rough track setup. You can find that setup here
In order to run it you need 3x2.1 pistons and 3x2.0 pistons. (They are marked on the sheet as 3.1 and 3.0).

Matt W 7/7/17 - What is overdrive and when should I use it?
The NB48.4 comes stock with a 12t pinion (TKR8152) and the 39t ring (TKR8151) in both the front and rear and the EB48.4 has a 12t pinion (TKR8152B) and the 40t ring (TKR8151B) in both the front and rear.

The two sets of gears are used to overdrive the front of the EBs or underdrive the rear of the NBs. If you have both vehicles and want to try underdrive it's as easy as swapping the front diff and pinion of the EB and the rear diff and pinion of the NB. Underdrive helps on very loose tracks, when you need more on power steering or if the rear of the car feels loose.

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.

looking forward to hearing more about this version. The big thing I am curious on is with the changes how well it will work on the more rough loose conditions we can see here. Also, if these changes will make there way into an SCT410.4 version.

Spring talk...

These are the springs recommended to have in your box (softest to hardest):
Front: Grey, Black, Pink
Rear: Yellow, orange, Red

Kit Springs are Black Front and Orange Rear, so if you buy the .4 kit, you'll have 2 of the 6 pairs right away.

Remember these are the Low Frequency (LF) springs and they work with the older versions of this car too. So even if you aren't in the market for a .4 yet, I suggest grabbing the springs.

I was just going to ask what springs came in the kit. Perfect timing haha.

What do you find is common combo for blown out big jump loose tracks for springs? Don't get around high grip stuff here for 1/8 e buggy.

Typically on loose, blown out tracks we will lower the spring rate to gray front and yellow rear. This will allow the car to roll a little more (generate more side bite) and it also better on the bumps. Really bumpy tracks we also go to fewer and larger hole pistons. We will have setup sheets posted from Ryan's and Joe's buggies soon.

I really like the New Recommended Indoor setup for the .3, all I changed was 1 step softer rear spring. I was planning on starting with that on the .4 or should I go with the kit setup?

I club race on a true off-road track, bumps, holes, rooster tails. It's alot of fun. So I can probably help a bit with blown out conditions.

On the .3, I ran 500/550 with 3x2.1 pistons, and the black\orange LF springs. I wanted to try the grey\yellow LF springs, but snowfall hit before I could.

I have a feeling whatever our current spring\piston\oil combinations have been on the .3 buggies, will be similar on the .4. Then adjust from there.

The caveat to that being, the guys that haven't done any testing with the LF springs on the .3 buggies. If you haven't, and still running the OG buggy springs, start at 1 color softer than the buggy springs when going to the LF. And you'll also want to play with oils. I dropped my oil 200CST when I switched to the LF springs.

Basically, the guys that have already played and test-n-tuned the LF springs, and found what they liked, will be at an advantage when switching to the .4 VS. the guys that haven't.

Thanks Matt, I look forward to seeing what they did/changed from stock, and if their setups are close to their .3 setups.

Thanks for the info. Feels nice to know there is someone on the other end for a company vehicle you are considering.

Looking forward to seeing the setup sheets.

Good stuff. I'll be coming from a different vehicle if I go with Tekno (which looks likely) and was curious if the whole LF spring thing will make its way to the sct410 side of things and if not is there a reason?

I haven't gotten to play with any of the new stuff yet as it's off season for me, but I was running Pink and Red/Orange on my car. Matt gave good feedback. I would definitely start there.

Not sure. I hear no, but I know a few people have tested them on the rear of the SCT. The LF springs for the front are too tall, and we wouldn't be able to get to some ride heights required for sct.
