GENERAL BUILD TIPS
----Use Threadlock! Tekno Vehicles have many metal-to-metal contacts throughout, prevent screws from backing out with a light dab of threadlocker on each screw that threads into metal (do not use threadlock on screws that thread into plastic)
----When building you diffs, take your time to make sure they go together correctly for a smooth and long lasting diff. Check out Ryan's videos below for tips on building and making them smoother
----Be careful when using a power screwdriver on screws that thread into plastic. Use a low clutch setting, and if necessary use a normal hex tool to check tightness
----Use a dab of grease when building each of the CVDs, and make sure a film covers the entire 'ball' of each CVD before installing into axle. Will drastically increase CVD life as well as improve handling
----Use a product such as Protek Premium Blue O-ring grease or Associated Green Slime on shock and diff O-rings to prevent swelling and oil seepage
----When building shocks, the best method we've found for consistent shock builds every time is a little different than whats in the manuals. First, place and seat the bladder into the shock cap. Fill the shocks with desired fluid and pump to remove trapped air. Thread cap onto body about 2-3 turns. Push shaft slowly into body for desired rebound, and hold in position while slowly screwing the body into the cap with the bleed screw facing down or to the side. Wipe away oil and the shock is ready!

*For the ultimate in identical shocks, use a calipers when setting your rebound. I measure the distance between the lowest shaft guide and the top of the shaft threads. For the Buggy shocks, I set this distance at 16mm for the Rear shocks and 14mm for the Front shocks to achieve minimal rebound and to get the least amount of air in the shock when its built.

STEERING LIMITERS
Yes, we know people like lots of steering. Our pro drivers tell us this all the time . Something to keep in mind though about steering...

The design of the EB/NB line of vehicles has more steering throw than any other vehicle on the market. Probably by a good 5 or more degrees. At first we thought this was a huge advantage. Lately, through constant testing, we have found the cars are faster and waaaaay more consistent with less steering throw.

So if you're not using the built in steering stops, you're doing yourself a huge disservice. We are using 4 steering limiter washers on the EB/NB/SC and the results have been awesome. Yes, the turning radius is reduced, but lap times and consistency have proven this is a non-factor.

Here's what goes wrong with too much steering throw:
Rear end washes out when landing jumps
Rear end continues to come around exiting corners
Feels like you are struggling for traction at times
Bump handling is unpredictable
Initial steering is extremely twitchy
And other issues to be sure

Here's what's going on. The last 5+ degrees of steering throw happen very quickly and the servo has very very little leverage on the wheels at full throw. This causes the inside wheel to act erratically and get tossed left/right at the whims of the track surface. Without a positive stop there, the inside wheel is going crazy and causing inconsistencies with the handling. The CV's can accommodate this extreme working angle, but there is more chatter which creates further issues.

Even if you just limit your EPA, the inside wheel is still free to move too far when the conditions arise. So install the washers first, then reset your EPA to match.

There are literally dozens of other adjustments that will result in more steering if desired (shocks, springs, ride height, sway bars, diffs, camber links, toe, etc.). By first limiting the throw, you can focus on creating more 'setup steering'. Think of setup steering as being more consistent vs. mechanical steering (i.e. throw).

Additionally, you won't be fighting the car so you will be spending less time tuning something bad out and more time tuning good stuff in.

NERF BAR INSTALLATION
Quote from Shark413
I just wanted to point out one thing that is not mentioned in the manual (at least I don't think it is). The nerf bars look the same but they are not symmetrical and are actually two different sizes. I noticed this while playing around with the air guards. The side pods on the Tekno SCT410 are made just wide enough to contain the battery (left side) and servo/esc (right side). And the chassis is just wide enough to provide support for the battery and motor. Since the side pods are of different sizes (width) the nerf bars had to also be of different sizes so that the overall width is symmetrical. Just another example of great Tekno design, they could have made the chassis and side pods symmetrical but it would not have been an efficient use of space/materials and the balance would not be as good. Also the nerf bars have a taper, and the flat side needs to be facing up so the air guards fit flush (see the pictures below) and you get max ground clearance.


http://i142.photobucket.com/albums/r...pse8e1c268.jpg
You can clearly see the nerf bar on the left is shorter.

http://i142.photobucket.com/albums/r...ps708eb689.jpg
Another angle. And you can see the taper in the nerf bar, one side is flat the other is curved. Flat side should be facing up.

http://i142.photobucket.com/albums/r...ps10f63e8c.jpg
Shorter nerf bar needs to be on the right side.


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.

It will also print nicely on a 8.5x11 piece of paper to keep in your track bag for quick reference while at the track. Also, if anyone wants any other springs added (I think I got most of the popular ones) please let me know and if you find any errors please let me know.

WHEEL FITMENT
The SCT410 was designed to run SCTE and SC104x4 wheels. We have found that some wheels made to fit these trucks have slight differences from manufacturer to manufacturer. If your wheel rubs the steering link screw you can remove the all of the bumpsteer washers above the ballend to lower the head of the screw. If it still hits you can remove the washers under the ballend (be sure to adjust your bumpsteer setting on the ackermann plate to compensate). If it still rubs after that running a cap head screw in place of the socket head should remove any chance of the wheel hitting the screw. Here's a list of wheels that fit with and without modification.

GEARING RECOMMENDATIONS
These recommendations are based on 2s 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 SCT410 info and adjust the pinion gear until you are close to your original top speed. NOTE: when running the split diff the smallest pinion you can fit is a 14 tooth.
Small track (50-100 ft straight)
3600-4000 kv 13-16 tooth pinion
4400-4800 kv 12-15 tooth pinion
5000-5400 kv 11-14 tooth pinion
Medium track (100-150 ft straight)
3600-4000 kv 15-18 tooth pinion
4400-4800 kv 14-17 tooth pinion
5000-5400 kv 13-16 tooth pinion
Large track (150-200 ft straight)
3600-4000 kv 16-19 tooth pinion
4400-4800 kv 15-18 tooth pinion
5000-5400 kv 14-17 tooth pinion

INNER HINGE PIN ADJUSTMENTS
The SCT410 has adjustable hinge pin holders that allow users to fine tune their truck for different tracks, conditions, or driving styles.
You can adjust the amount of front arm "sweep" in 0.5 degree increments from 2 degree forward to 2 degree back.

This picture is top down, looking at the left side of the hingepin blocks.
http://i1341.photobucket.com/albums/...pszvgo3ceb.jpg
You can adjust the amount of arm kick-up in 0.5 degree increments from 8 degrees up to 12 degrees. This in turn also adjusts your total caster angle from 18-22 degrees.
http://i1341.photobucket.com/albums/...psaargedyi.jpg

You can adjust the rear toe angle in 0.5 degree increments from 1 degrees up to 5 degrees.
This picture is top down, looking at the left side of the hingepin blocks.
http://i1341.photobucket.com/albums/...ps02lgrgsg.jpg


You can adjust the rear anti squat angle in 0.5 degree increments from 1 degree up to 5 degrees with the stock plastic hingepin holders and 0 to 4 degrees with the addition of the aluminum C block.

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 ;)


BODY FITMENT
Most aftermarket bodies now have several sets of dimples that mark where the body posts are for different manufacturers. Our posts can be adjusted to directly line up with those of the Losi SCTE, Traxxas Slash, and the Durango. Any body designed for a 1/10th scale SC truck will fit, you just may have to find the body post locations on your own.

ALUMINUM HEXES
The stock kit comes with an aluminum hex that is secured to the axle with a setscrew, PN: TKR5571M.
There are two versions of clamping hexes that Tekno makes, PN: TKR1654X, originally designed for the Slash and SC104x4, and PN: TKR5571A. TKR1654X will however increase your track width by 1mm per side. If you are running SCTE wheels your truck will still be ROAR legal width with the wider hexes. If you are running SC10 4X4 wheels you will be over the ROAR maximum with the wider hexes. With the narrower hexes and moving the arms inner hingepins in it might be possible that some the manufactures wheels for the SC104x4 may be legal.
NOTE: Tekno's hex kit comes with shims that are designed to go between the drive pin and the bearing. They are there to take up any slop due to manufacturing tolerances. They may or may not be needed. It is normal for one wheel to need one or two shims and another to need zero. Install the hex without any shims and install the wheel as if you were going to run the car. If there is excessive play, add one shim and retest. The goal is to have just a tick of free play, you do not want it so tight that it binds up.

17mm HEXES
http://i270.photobucket.com/albums/j...ELADAPTORS.jpg

Ok guys, we couldn't decide to use a slide on the pin or side load for
these hexes, so we just did both.
these hexes are made to fit the 6 mm axle.
the retaining nuts can be used with either loading method, but is not
necessary for the the side load model.
the only issue was that due to the hole location in the axle, you may not be
able to use the 6 mm shim. I had to make it like that to make it fit.

CAMBER LINK INFO
The camber links need a 4mm turnbuckle wrench for adjustment. We've found that some wrenches work exceptionally well.-

Inner camber link adjustment
This is a quote from Shark413
I also want to thank Cain for his feedback on the rear inner camber link mounting screws. At first I didn't think it was a huge problem, but then I went to adjust the inner link mount and found it was a royal pain to remove the screw. Per the instructions I have the screw head facing the rear (towards the rear bumper) it is almost impossible to get a normal 2.5mm hex wrench in there without removing the upper rear bumper mount. Cain suggested turning the screw around for easier access. I decided to take his advice and turned the screws around and I just wanted to post a few pictures to better explain the issue and fix. Cain I knew you wouldn't let me down, thanks again.

http://i142.photobucket.com/albums/r...psc04813ce.jpg
This is the problem. This is the rear inner camber link mounting screw when installed per the instructions.

http://i142.photobucket.com/albums/r...ps13f844a0.jpg
If you want to make adjustments, you can't get a hex wrench on the screw head.

http://i142.photobucket.com/albums/r...ps12e32513.jpg
You can get a short allen wrench or ball end hex wrench in there to loosen the screw, but.....

http://i142.photobucket.com/albums/r...ps53a6bc08.jpg
If you want to move the screw to a different hole it hits the upper rear bumper mount.

http://i142.photobucket.com/albums/r...ps14bbf5cc.jpg
By reversing the screw you can remove it once you remove the nut. Installing it requires you to hold the nut with pilers as you tighten the screw.

http://i142.photobucket.com/albums/r...ps7c096f28.jpg
And this is what it looks like all bolted down. You can now access the screw/nut and are able to adjust the screw location without removing the bumper mount.

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.

Tekno Screw List:

Tekno #1523 3x10mm Flat Head 2
Tekno #1529 3x20mm Cap Head 20
Tekno #1341 4x6mm Flat Head 6
Tekno #1525 3x14mm Cap Head 18

It's going to be a great evolution on an already outstanding platform!

revhead145 03-17-2015 07:55 PM

Mine is already in pre-order :)

Monkey#39 03-17-2015 10:27 PM

Has this truck been announced anywhere, or up for pre-order

They list the parts to upgrade. I wonder if it is cheaper to buy a new kit rather than upgrade.

Many folks already have many of those upgraded parts on their SCT410, such as an aluminum front center drive shaft, etc. Yes, some more parts are lightened, but it will really only take a couple parts to update the handling characteristics if that is what you're looking for: arms and towers. Other things are swap in option parts like the new style of hinge pin holder, or are things you're likely to replace periodically anyway due to wear/slop such as stub axles and spindles.

If you want to immediately upgrade everything, then yes, getting a new truck is probably the best thing to do (though still more expensive...but then you have 2 trucks).

does this lcg motor mount also have a 36mm diameter can max ?

plastic split diff ?

As many SCT410 owners are looking at this and trying to weigh options. What are the chances that a "geometry update kit" will be released? I know a lot of people that have the lightened drive train, 7075 chassis, and other option parts that have been available. But to bundle up the hinge pin holders with the square pills and the new arms and hubs, or any other newly introduced features would be a nice gesture to support the many 1.0 folks out here.

As for the split center diff mount.. I knew they would not blow the chance to sell upgrades to people. So the plastic split diff makes sense to me.

Apco1 03-19-2015 06:50 AM

Is a composite cross pin a good idea? Sounds like they are introducing a failure point. How much weight could you possibly save with a composite pin vs a steel one? All the other updates sound good.

lpspeed2 03-19-2015 07:19 AM

hmmmmm, I like MOST of what I see! But have to do more researching to see if it will be worth selling the current one to upgrade.
