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!

Will the robotronics heavy duty servo arm work with this kit?

It will work, but youll need to shim the steering rod up on the servo saver end. The HB mount is a good one if youre on a budget. http://www.amain.com/rc-cars/hot-bod...s67169/p148908

Ok, great. Didn't know that. I will look it up and see how to do it. I'm almost done with the BEC install. I wonder if I should try that first strictly for troubleshooting sake.

Default Countersunk holes?

Am I correct in assuming the screws going into te steering tubes, should be countersunk?

As you can see neither one is countersunk - just want to confirm before i contact Tekno.

I would try the firmware update first.

I see a lot are changing springs. Is the stock setup that far off? I'm fixing to build a new 410.3 for a buddy and want a decent starting point for him. I read about the stock springs not allowing for proper ride height. I was planning on compressing the springs overnight before assembly to allow them to be softer than stock. Any tips?

I did buy the 6 x 1.6 pistons which allow for more resistance with the oil and piston, I'm running grey front with black springs and have 30 in the front and 27.5 in the rear. Been liking his set up for my track. 100'x200', bumpy, hard packed with dusty. Tight and technical. I wanted to have higher speed turning with chassis roll and this setup seems to work well. So I am afraid you will probably have to buy springs at least and play with different shock oil weights Pistons would come next.

The stock setup is pretty decent on high grip indoor stuff, rear of truck is soft but seem's to work, I wen't to 27.5wt oil in rear as the stock weight is REALLY light. I'm using pink springs in front as the stock greens were a bit too stiff for me ( I STILL cant get proper ride height in front with no preload) Only changes I have made is a little heavier rear oil/Pink front springs/went out one hole from stock on the front tower/moved the rear hubs forward with the 2 big shims in rear and the single little shim in front.Truck is pretty good at this point but I feel it would be REALLY good if I could get the ride height right in front, guess I'm going to have to match up and pick out springs from another company to get things right as I have the same issue with my eb48sl but worse on that one cause its front and rear to high LOL

What advantage does changing pistons have over thicker or thinner oils? Wouldnt an oil weight change be the same thing?

Dragonfueled,

I'm pretty new as well and to be honest I bought them because a few people recommended them. Some complaints that are out there is how soft the suspension is. I think that with less oil flow with medium weight oil it handles better than more flow with heavier oil. I'm just playing around with different things and I truly do not know what the end effect is with the two. I know its working well for me and I had a few drivers run my truck at the last race and they were impressed with how well it was driving.

So what Pistons do you recommend? I'm building a basher so a little more dampening might be good.
Allready have allumimum hinge pin braces and diff pins. Just got alluminum servo horn.Trying to get all my basher parts before I build it.

Oil changes how fast the piston moves through it. Piston effects how much pack there is in the shock. If you run a heavier oil, you may get enough the shocks firm enough for big jumps, but little bumps will upset the truck. Changing the piston will give you the pack for big jumps, but still allow low speed handling.

8x1.3 or 6x1.5 depending where you will run your shocks on the arm. Inner mount 8 hole, outer mount 6 hole.

+1 you change the pistons for the pack. the 10 x 1.2 pistons I never felt like I got enough pack from the version 1 and sounds like its still the case.
