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.

Indoor ,high bite, alot of jumps , Fairly smooth: I started with yellow , then to green. These were to high and bouncing around to much. So now using pink. Going to try blk next. But as of now IMO anything heavier then say pink is maybe more for a heavier 1/8 set up. Things might be totally different outdoors ...

I cut one coil of my front/rear springs.I running them at 21mm,fr/22mm,rr with VRP pistons(5x1.5)/Losi oil 20wt front and rear. Works great on indoor high-bite track. I actually run the same combination on my 1/8 super-lite on 4s with the exception of the ride height....22mm,fr/23mm,rr

Yea bro, it def crossed my mind as far a trimming a set of yellows or greens. But what stopped me is , if its wrong a new set is on the other side of the US & 7 days wait.. Yep , that ride height is pretty much the sweet spot..Indoors anyway..

I have a TA SC5M 2WD running on a medium outdoor dusty loose track. They run the 2WD and 4WD's together. My 2WD on that track is like driving on ice. It is a lot of fun, but I can't run with the 4WD's. The Tekno is now on my short list.
I would like to share the same batteries I use for my Losi 1/8 which are 4S 5800's. The Tekno tray is the right size. BTW, the track does not care what batteries you use. Has anyone used a 1/8 ESC and motor in this? In my Losi 1/8, I run the Mamba 2 with Neu 2200KV motor on 4S and 6S and could not be happier. I am open to an ESC and motor combo that is lighter that can run on 4S. Thoughts?

Tower Hobbies has this for $369 with a $60 off coupon if you spend over $379 and free shipping.

Manual says "M4" once, "M5" twice and Google gives you this:
http://www.teknorc.com/shop/tkr1215-...ed-black-4pcs/

So chances are that "M4" is probably just a typo...

The 410.1 uses an M4 and the 410.3 uses an M5.

Twice I've been at the track and I've realized that my 4wd truck was really only a 2wd truck.
The diff. Coupler was not tightened down, it was just spinning. I'm putting lock tight on the treads and tightening what am I doing wrong ?

Wheel nut - What brought this on was I wanted to purchase Hudy quick wheel nut for there set up station. So I ordered the off road 10 scale nut reverseable,, no good . to small. Then I ordered 8th scale wheel nut ,to big no good again.. Now Im stuck with $60 worth of nuts ... Terrific!. So I called Hudy . Turns out they dont make 5mm which from what they say is kinda limited to the 410.3..

Yep- Tekno is the only company that I know if that is using 5mm axles. The 4mm were breaking a lot so their solution was the 5mm end.
My solution is the SL stub axles with Traxxas 17mm hex. That way I can use my Hudy station.
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.
http://www.teknorc.com/shop/tkr5571-...ct-width-4pcs/

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.

damn auto correct- yes, clean and blue loc-tite. You have to let it cure before it is really effective, so do it at least the day before you plan to use the truck. Make sure you have a good sharp tool so you don't strip the screw, and tighten that grub screw nice and tight.

Default Loc tite alternative

Please stop using loc tite. I've been using this stuff for years, nothing falls off or comes loose in my rigs. This stuff is specifically made for high shock and vibration. I use the 30cc because I use it on more than just RC but the 5ml tube would last a good long time for rc stuff.
