If you are really sure that everything is centered and zeroed, and that much difference occurs even with no steering links actually connected, than something appears to be damaged, maybe the servo?

Seems like a bad servo from what your saying and what I'm seeing from your pic.
If you have another transmitter and Rx, I would plug that servo into the other one and retest. That will determine if it's something else for sure.

What is your trim setting for your steering in the radio? That whole range looks limited to me.

As a quick test, plug the servo into the throttle channel and test the travel. If it's still limited then it's most likely a bad servo. If it's fine then it's the radio. It's unlikely the radio has limited travel on both channels.

Does your radio have sub-trim in addition to trim? Check that both sub-trim and trim are set to 0 when installing the servo horn.

I've been working on my Tekno for a little over a year trying to get it as good or better than my previous truck(scte). It has been a challenge to say the least but i do love the challenge and i do love this truck.
I've always feel that the truck lacking on a right turn layout and have spend a lot of time chasing setups,tires,springs etc. Finally ....as i scale the truck and to my surprise the truck isn't balance from left to right.(heavier on right side) Battery mod only move the weight slightly back but not side to side. I knew what i have to do but dragging my feet knowing the the esc wires are too short to relocate to the left rear of the truck. But one night after taking a podium on a Saturday night race in most of the time but never the 1st place, i came home and get busy on the job in hand.
Anyway,the Hobbywing fit perfectly on the left rear and since i was in a cutting mode i also eliminated the radio box to loose 26 more grams .
I thought i would share this with you guys because i know i'm tired of chasing those Losi guys lol
and happy to say i podium in 1st this wkd with only a few laps on this new change.

It was around 60% right and 40% left. My battery is 331 grams.After the mod the weight bias is now almost 50/50 front to rear and left to right.

So i'm now wondering what Weight battery tekno used to balance ?

Also, To eliminate some inconsistency, did you also balance without shocks & Wheels attached ?

Was Car coming in contact with scale in exact same location on all scales?

Switch scales around?

I noticed you removed the mud guards from earlier photo . Reason for that ?

Tekno RC created this layout for a 1/8 scale buggy with 4 cells at the left side. So that´s nearly double the weight of our batteries with 2 cells.

You are on the right way, see what i did. Nice to see, that this ESC fits, too.

Had the first race this year on carpet.
The car was outstandig, it seems to suck to the ground. Reduced ride hight and used stiffer oils in the shocks, maybe around 450, green front and grey springs in the back. Pistons: MIP. Jumping is still difficult, had to stay on the throttle in the air, but with some more practice it is perfekt to control the landing on the back face of the jumps. I just should get a much more faster left finger...
This is my 2. jear with the truck, the track was very "jumpy" and i became 5. of 7 starters with much more experince.

But the buggy motors are heavier as well
