I'd say 42-48 depending on track size and traction.

I agree. Maybe add up to 51 pinion

Default Simmetry of steering angle on TCXX

Hi all a question please
putting my TCXX model on the system setup I have always noticed a difference in steering angle between left and right, to have the same symmetry I must stop the maximum steering angle at 22.5 and 17 (out and int.), by adjusting the trim steering from the radio to get the same angle between left and right. Going beyond this value, one side of the steering starts to differ much from the other, and the model loses the steering symmetry between left and right, this happens with car model have identical distances between the four upper arms, exact adjustment for DownStop, ride height, with battery, esc, servo, fan, etc etc. I found this with different chassis, I exclude mistakes of holes distances.
Happens to you, or I'm wrong something?
Thanks

You need to play with the length of the turn buckle between the servo horn and steering rack. I have about 27 degrees steering left and right on the setup station.

Have you a photo of your servo horn?
I used a servo saver (3 racing metal) the distance between the center of servo to the out hole it's only 18 mm, without servo saver the distance it's too long (servo horn), but why I loses the symmetry after a certain angle?

Hello,
First, your radio must be at 100% left and right.
Your arms must have the same size. Then your servo link must be at 90 degrees. And after that with your setup weels you turn your weels on left and right. When you do that your weels must have the same midle center. If not change the size of your servo link.
It's very long to appli that and difficult to explain it if no body shaw you how to do.

Hi !
The steering dual rate should be 100% by side, but actually if I wont the same symmetry I must adjust it with different values ​​between the right and left.Actually the servo is positioned at 90, but the turnbuckle that connects the servo saver to the central metal steering arm works slightly angled (as shown on the plan view of the model on the assembly manual) and not perfectly parallel I would like.
I don't think that that is the real problem...
Thanks for the advice I will take inspiration for some adjustments.
Bye

sorry didn't have time for photos yet. My dual rate is actually 100% and epa is different between left and right. I think its 95% and 120% on my futaba radio and servo. This still yields 27 degrees left and right.

Setting steering takes time.. You have to set subtrim, servo saver position on the servo, turnbuckle length, epa, and dual rate, then check on the setup station. rinse and repeat until you get it the way you want. I know, its a long process.

That's weird something isn't right then, I get 32deg each way on my tcxx.

I also over heard Andy talking about a new HB for next year at the aoc.
His car was a lot different to the kit, but I suspose that's apart of testing new things.
