Welcome to the EB4.4 Wiki page.
If you edit the page, please add your name and date prior to your addition. While an admin can view the history, this makes it easier for everyone to just check updates. We'll put the newest additions at the top.

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.

That's funny because my current eb48sl build has beeb on hold for that exact reason. But I'm on my way to the hardware store to pickup stainless varieties of everything the kit needs as a backup. Sadly I've had a lot of weird issues with my build that I've never experienced with any of my other Tekno kits.

I wouldn't run stainless unless you plan on getting your car wet often, they're not as strong as the black oxide coated screws.

thanks for the tip
I'll have to see what they've got at the store today because I'm dying to get back to work on this kit lol. I do have some titanium screws coming but they won't be here for a day or two.

TonyScrewz has equipped my vehicles. His stuff works quite well and he shipped fast the last few orders I have had from him.

Its interesting to see that Emulsion (if I am reading it right) will become like the default for the buggy. Maybe its because the mains are not as long, but I do recall at least from a nitro point of view concerns about shock consistency over a long main with emulsion. But emulsion does work well from what I have seen and told.

My plan as well. I just got my .3 to where I am really comfortable pushing it as hard as I can, so i will have both until the .4 is better/faster

Oh I definitely intend to get a bunch from Tony's screws but I was just trying to keep the build going as I'm bored to death at home right now lol

All of our team guys run emulsion in their nitros now too. If you build them how the kit instructs with the second bleed they stay pretty consistent over the long mains.

I have become a professional package wrapper these days with the various gifts that come in from Amazon. I should charge a fee seeing how well I wrap versus my wifes attempts.

Good stuff. I liked the feel of the emulsion build with my daughters old Tekno SCT410. it was like the one thing that was different between our 2 vehicles back in the old days.

I am curious now how long before we see any more ".4" vehicle annoucements

After seeing the second bleed method, I started doing that on all of my cars, even 1/10. It really does make a difference.

Lol that's good news because you'll be getting an order in soon! Status update though. I did have to stick with stainless for today as that's all they had. But I only got the screw I needed so I'll still be getting a full kit soon.
