IMPORTANT INFORMATION AND UPDATES:

SERVO SAVER CENTERING
So we have looked into some of the servo saver inconsistencies and found a solution for the wandering. Please see attached image. The face highlighted in blue needs to be sanded down about 0.1mm. The flashing from the mold prevents the servo saver from seating 100%. After doing this and tightening the spring down, it will hold as intended.
We'll look into a fix for this in the future, but it requires a mold change so it won't be the fastest fix ever. What is outlined above works great though.


Diff Gasket Tip. The gasket fits really snug in the ring gears of the front and rear diffs and the holes in the gasket are precisely the size of the holes in the ring gear. So, install the gasket in the ring gear at an angle and get the first hole aligned perfectly before working the rest of the gasket in. You can smear a little bit of black grease on both sides of the gasket first. Once the gasket is fully seated, you can not turn it within the ring gear.

Outer Diff Shims Tip. Getting the diff in the housings with one shim on each side can be challenging. They are delicate, thin, and have nothing to keep them in place while you try to install the diff. It's very easy to buckle/bend one or miss getting it in the housing. What you can do to make installation easier is to cut a .5mm x 30-40 degree chamfer on the inside of each of the four corners of the bearing lip of each diff housing halve (8 total for front diff, 8 total for rear diff). [See pic below] This allows a bit of alignment assistance to get the diff installed without damaging the shims.


SPRING CHART


I also found this chart comparing Losi 8ight and Hot Bodies D8 springs, both of which fit Tekno shocks.


I made a chart of the Kyosho springs.



PISTON CHART

BEARING CHART


Avid RC now makes a bearing kit.
http://avidrc.com/flexkit/?kit=524&kitname=SCT410

SHOCK OILS
The kit comes with 450cSt front and 350cSt rear shock oils. This translates to Losi 35 and Associated 37.5 for the front, Losi 27.5 and Associated 30 for the rear. If you're switching to any other companies oils, starting within 5 wt (or 50cSt) of those should be fine for your first runs. Use that as a starting point and tune from there.


GEARING RECOMMENDATIONS
These recommendations are based on 4s lipo setups and are guidelines only. If you're switching to this vehicle from another that you had achieved a speed you liked I highly recommend visiting this site -http://scriptasylum.com/rc_speed/top_speed.html, inputting your old/current vehicles information, recording that data, then input the EB48 info and adjust the pinion gear until you are close to your original top speed.
Small track (50-100 ft straight)
1600-1800 kv 15-18 tooth pinion
1800-2000 kv 14-16 tooth pinion
2000-2200 kv 13-15 tooth pinion
Medium track (100-150 ft straight)
1600-1800 kv 18-20 tooth pinion
1800-2000 kv 17-19 tooth pinion
2000-2200 kv 16-18 tooth pinion
Large track (150-200 ft straight)
1600-1800 kv 19-21 tooth pinion
1800-2000 kv 18-20 tooth pinion
2000-2200 kv 17-19 tooth pinion

INNER HINGE PIN ADJUSTMENTS
The EB48 has adjustable hinge pin holders that allow users to fine tune their truck for different tracks, conditions, or driving styles.
The front outer adjusts the amount of front arm "sweep" in 0.5 degree increments from 1 degree forward to 1 degree back.


The front inner adjusts the amount of arm kick-up in 0.5 degree increments from 10 degrees up to 12 degrees. This in turn also adjusts your total caster angle from 20-22 degrees.
Looking at the picture, the top option is 10 and 20 degrees (kick-up and total caster) and the bottom is 12 and 22 degrees.


The rear outer adjusts your toe angle in 0.5 degree increments from 1 degree up to 3 degrees using the standard holder and 2.5 degrees up to 4.5 degrees using the +1.5 holder (now standard on the EB48.2)



The rear inner adjust anti squat angle in 0.5 degree increments from 1 degree up to 3 degrees.


Arm Sweep
The purpose of sweeping the arm forward or backward is mostly to sweep the driveshafts forward or backward. When the driveshafts are angled it changes how the car reacts on and off power. (This goes for the rear driveshafts as well.)

When the driveshafts are swept forwards, the stub axles are being twisted down toward the ground, pushing down on the tires and lifting the front of the chassis. This can be helpful in really bumpy sections to keep the front up and not dig in. It will also create more weight transfer to the front during braking which will increase your off-power steering.
When the driveshafts are swept backwards, the stub axles are now being twisted up, lifting the tires and pushing the chassis down. We've found that the biggest benefit to sweeping the arms back is jump landing. With the arms back, the car kind of "sucks" itself to the ground. It settles much faster and allows you to get on the throttle immediately. During breaking and off throttle the chassis will stay a little flatter front to back and either feel "pushy" or more controlled into the corner.

You can adjust the rear sweep by changing the wheelbase.
It's possible to have toe in on the rear and have the axles swept backwards (not on our car, I'm just making a generalization), but it doesn't handle well. It will squat really hard on acceleration and the nose will dip under braking. If any of you have ever driven a Revo with the long wheelbase rear arms you know what I'm talking about

Skid plates
APE-RC makes a stainless steel skid-plate. Here's a link to his online store.


T-Bone Racing makes several bumpers/skids in different sizes for the front and rear of the buggy.

Durango Makes aluminum links that can fit-


TDR310216 - 5x48mm

TDR310214 - 5x64mm

TDR310215 - 4x60mm

A note about the Durango links, on the buggy, 5x64 works on both front and rear links unless you run them really short (this is more of an issue on the front then the rear). The front truck camber links are already shorter so I think only the 5x48's will fit. The rear camber links are the same as the buggy's so a 5x64 should fit, but if you're running a shorter link you may either have to cut it down or run the 5x48. The 4x60 fit the steering links on both the truck and buggy.


Lightweight parts and chassis modding
Carbon Towers
Several manufacturers now make carbon fiber towers for the SCT410 and EB48.
-SNR Graphite makes front and rear towers as well as a center diff top plate. http://www.snrgraphite.com/index.php...0f722349d96255

Stock Body


ALTERNATIVE CHASSIS
The stock SCT chassis is stamped 4mm 7075 black anodized aluminum with a minimum amount of cutouts.


The stock EB48 chassis is milled 7075 hard anodized aluminum with a number of cutouts. It decreases weight, increases flex, and maintains stock hole locations and chassis thickness.



M2CRacing released 2 new chassis-



M2C RACING is pleased to announce the release of our Tekno Electric
chassis for the 1/8 scale and sct410.
We will have 2 models. The standard design and the modded model which
will move the battery tray back 10 mm.
These chassis are made using 1/8 inch(3.25mm) thick 7075 aircraft grade materials and clear anodized.

use of the material greatly increases the overall life of the chassis.

we have tested and tweeked these chassis to provide the racers a top notch chassis that will perform very well on all surfaces.

This model is made for the tracks with a high wear situations like the tracks we have out West, up north and in Canada

It is important to note that these skid plates fit flush to the bottom of the chassis and will not effect the droop settings and cause you to

scrub speed on the landings.

FEATURES:

We have adopted this model so that if you wish you can cut off the front bumper to help the vehicle not to get upset on landings

and increase ground clearance.

front and rear skid plates.

It is advised you replace the skid plate when the edge of the skid plate wears down to 1 mm.

This will make the chassis last much longer.

hardened droop stops to prevent chassis wear and droop changes.

Battery Mod
Several people are modding their battery tray to move the battery back to the front of the brake servo mount. Here's an example by sramos.

Heres the jist of what i did. the rubber that goes along the side of battery tray is from a rubber pipe couple i picked home from home depot and cut off and glued in. put a big enough foam in rear to keep well away from diff.





OVERDRIVE OPTION
A track with loose conditions is where you'll see the biggest benefit of running an overdrive setup. To achieve this you will need to run the truggy ring and pinion in the rear of the buggy.
You have to use both the pinion and ring gear from the truggy. The truggy's ring gear has a different offset to mate up with the smaller 9t pinion gear.

I built up a whole truggy diff so that I could quickly swap out the diff and pinion gear at the track. It's more expensive that way but the time it saves you at the track is worth it.

For those that are thinking of trying the truggy gears in the rear, here's a couple of tips/things to be aware of -
-You'll need to go up 1 tooth on your pinion gear or you'll lose a noticeable amount of top speed.
-You may want to strongly consider going up in your center diff oil if you're running 5k or less.
-Be aware that your buggy will jump with more of a "nose up attitude" then before.
-Your buggy will now have a slight drag brake off-power coming from the rear end.


ALUMINUM SCREW LISTING

From MattP-
I just made a list of all the screws, washers and nuts needed to convert a Tekno ride over to all aluminum screws. I listed the stock replacement Tekno screw part number first with details beside each. Only screws I did not list for an aluminum swap are the diff screws holding the ring/spur on to the diff. That's a high load bearing screw and steel is a better choice there.

Is the EB48 it's own platform.... basically a full roller???

teknorc

iTrader: (2)

100% Tekno RC design. We designed everything on it, the diffs, the shocks, the chassis, the arms, everything...

This is not a conversion, it is a brand new platform .

blade329

iTrader: (114)

Reminds me of the Serpent 811e, from the looks of it. I'm guessing it's going to run dual packs. I wish I could go to RCX this weekend to check it out.

chirivita

That might be because the body is from the 811e and i think they've used some of its parts during testing/development.

It's a single pack layout.

blade329

iTrader: (114)

Really? I had an 811e. I can't see how you could fit a 4S under that body. It's a really low profile body. Maybe if you lay it on it's side, I suppose.

teknorc

iTrader: (2)

The Serpent body was used as a decoy .

The new buggy is narrower overall than any other buggy out there. It's a single pack layout. The dual pack layouts aren't as balanced. We explored the dual pack layouts, but they always came out heavy on the motor side in the computer. After we found this out we weighed one of the competing cars and sure enough it's out of balance (heavy on the motor side).

I made a whole post about why they are actually very unbalanced and bad for handling on the Tekno RC conversion thread. We'll be explaining why how the design came to be in the following weeks when we launch our new website.

And of course we will be discussing all of the details at the RCX show this weekend.

fireflysti

iTrader: (12)

I had a chance to drive the proto buggy for a few laps and first thing you notice is this thing turns on a dime. A combination of light weight and narrow chassis make this buggy handle like no other 1/8 buggy. It jumps better than anything I've driven and the exceleration is unmatchable, can't wait to get my kit.

blade329

iTrader: (114)

Oh, great. Now there is another buggy out there that I'm going to have to buy. Curse you, Tekno Can't wait to see it.

sjenkins97

iTrader: (7)

Is this going to be available right away(kits ready) when released or is it going to be a waiting game/delayed like so many other mfg's? (couldnt think of a better way to put it)

teknorc

iTrader: (2)

We're using RCX to announce/show the buggy. Release date will be summer. We wish it was earlier too .
