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!

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.

Also you can use TKR5571-17. It is a plastic hex conversion kit from Tekno. The plastic hex's don't work very well on the truck so throw them out, but you won't use them on the setup station. If you have the Hudy 1/8 set up station, the round parts in the photo in the link below are used to adapt the set up parts to the truck. The step on the round plastic part fits the axle hole on the set up tool, then use your wheel nut to tighten it down. I know it will be difficult to visualize but once you have it you will see what I am saying. You may have to ream out the hole in the round plastic part to fit the 5mm axle (they were designed for the 4mm axle), but the system works, tedious to install, but it works and cheap. I have been using it for a couple years with my SCT and does very well.

BTW- how much do you want for the 1/8 Hudy nuts? Not much use to you, but I could use them for my EB and now my SCT. PM me if you are interested in selling.
Gotcha MKL, I was going to pick up an aluminum dowel and cut and tap out my own .. Maybe scrap my idea who knows. Hey , tks for offering but now I gotta buy buy an 1/8 scale buggy to use them wheel nuts ..

I recently picked up a used 410.3 and I'm in need of a servo. What's the best bang for your buck as servos go? I'm going to be racing on a large, outdoor 1/8 track.

Also, are there any spare parts, springs, etc. that I should pick up right away? The truck already has a couple aluminum hinge pin blocks (A and D?).

That's an impossible question to answer. TLR fans will say no, while Tekno fans will say yes. But there are some people like myself who have both to play with.
My SCTE 2.0 is unquestionably lighter and quicker in some aspects, but the tekno stay planted in many scenarios a lot better that the SCTE. The tekno is much easier to tune to a track and over all requires less maintanance over time. They are both very tough trucks, so much so that I don't see any difference in crash durability.
The SCTE can turn in quicker it seems and is well suited to indoor and or smooth high traction tracks, but the tekno is good in any situation it seems. While one has more here the other has more there and vice versa. But as a long time losi fan I honestly feel the 410.3 is over all the better truck with all considered. But that is just my opinion and doesn't stand as fact. Consider the tekno is really the only comp the 2.0 has. You will see the podium with either truck. But it seems easier to get there with the tekno with minimal upgrade needs. You will spend much more on the losi in the end, I can promise you that.

Thanks for the input. I have a SCTE 2.0 now. Getting a EB48.3, and was wondering if its worth selling the Losi and getting a SCT410.3.

proliteandsc: I guess the big thing I would see about finding out is if the whole nose down jumping thing has been solved and the rough / loose track handling improved in comparison to the losi.

I am actually curious on that, is the sct410.3 now planted on loose tracks and doesn't have the nose down jumping issue? And if these were fixes done after the sct410.3 was released, what parts / setups have fixed this.

Thanks Jimmy.

Does anyone have any recommendations for diff fluid? The manual says 7K for front and center and 5K for rear. Is that a good start or should I be going higher?

I think that is a good place to start for diff fluids. I run 7/7/3

our current track is fast with small jumps so I can run very soft springs - black in the front and pink in the rear.. but I use huge 2.7mm swaybar in front and I think 2.6 in the rear? To make this setup work on the high speed high throttle sweepers w/ step downs.. you need thick as hell diff oil.

15k front
10k middle
10k rear.

this allows for serious steering if you encounter body roll - powers out of anything and does not whip around with one wheel holding all traction and the other going pizza cutter mode then landing like that and the pizza'd wheel shoots you sideways.

for a big jump track I had to go back to stiffer springs, smaller bars, and the 7/7/5 diff setup.

Hope that helps - ps I run 1/2 oz of weights at the back speed control area, I have the battery mod, and running a 16 pinon spur helps control the movement in the air (15 tooth was not enough to dig it out of a bad nose over).

Hope that helps.

It's a big 1/8 scale track. It's dirt (real dirt) and conditions can vary a lot. Usually, its dusty with low traction.

Angle of approach :

Bumpy track & steep angle jumps.

The front bumper needs to be removed to increase angle of approach beyond 50deg. Front bumper seems to be coming in contact with the ground before the wheels. Causing severe nose over by jamming the chassis into the ground.. The bumper lower bolt hole always full of dirt is a tell tail sign. Once removed your still able to run a lower ride height. However , now i'm looking to fit the 1/8 eb 48.3 part# tkr 5166 bumper. Which is much lower profile . Will it fit ? Starting to think this is due to wheels being to small for this rig..
