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.

Hello Caffeine357,
The kit does not come with an aluminum servo horn. You can use pretty much any horn you might have and we also offer our own which is clamping and offers two separate lever lengths.

Still seeing these as late dec for a variety of places. Any more news on that like packages shipped out to places like tower, etc?
good base or not, every top brand had conversions too, but they didn't half ass it and just copy it just because it works or is fast. No they innovate, proving there is more than one way to drive fast and more than one way to design fast cars. Hb is a copy. Plain and simple. No credit deserved there for copying design, regardless what it's capable of. Less r n d less work, good hb buggy thanks to tekno.

Yeah I see that one, I am looking for an overall chassis pic however if its just the same as the regular on the rest of the chassis that's fine, I was curious if there was more changes than just the rear end, as well as see how they changed the rear relative to the actual droop downstops.

I think you may want to take another look at what various top brands have been accused of based on various discussions concerning copying. You may be surprised based on comparison pictures and the discussions. Some of the recent vehicles have an uncanny look in comparison to others.


Looking forward to the first build posts. I am hopeful that the local track here will do 1/8 E buggy as the track is being built from a "1/10" perspective but is said to be SCT sized vehicle friendly, so I would think they will work good.

I am assuming the usual parts should be picked up for spares, however, with some of the changes done for new type of parts anything particular to pickup there that may wear faster than just normal maintenance items that you would be worth carrying as a spare? (ex- spare bearings for the new spindles)

Cain, recommend the normal spares, hinge pins, shock shafts, steel spur, 13x18x4 bearings, arms, spindles/carriers and hubs. Kit now comes with universals on all four corners and the plastics are very durable, so it will last quite a while.

Good stuff yeah the steel spur will most likely make an appearance for a piece of mind thing. The nylon spurs have been reasonably durable in the past but nothing like a steel spur lol.


Hey maybe you can answer this, I noticed on a motor side mud guard the hole opening in it to adjust the motor mount lower screw was just a slit and on another it was a big circle. Is that the only difference? If so I can just open it up with the dremel, etc.

Lastly, I heard the best lipo for balance was a 6500mah 4S pack, is that still the case?

Ae is crap in 1/8 buggy for stealing from mugen. A good brand in 1/10 off-road, but not 1/8. What's your point? I've been hammering ae for it. Not gonna give hb special treatment.

Joe's using shorthand describing the pistons. For his Smooth Track setup sheet, he lists his pistons as "4.9". This translates into "4 x 1.9mm holes".

On his rough track setup, he lists:

"3.1" for front => "3 x 2.1mm holes"
"3.0" for rear => "3 x 2.0mm holes"

Joe posted this on the Tekno RC Nation Facebook page:
4.9 = 4 hole x 1.9
3.1 = 3 hole x 2.1
3.0 = 3 hole x 2.0

The 4x1.9 are not out yet (being shipped with .4). The 3x2.1 (tkr6162) are out. 3x2.0, you may have to buy Tekno blank pistons (tkr6160) and drill three 2.0mm holes.

its interesting to see going with less and less holes but larger ones. Looking forward to seeing how they work out.

So when do we expect the next shipment of eb48.4s? Towers out.

Got to see the .4 go around the track yesterday at NEORCRC. Joe's, as expected, looked really good.
