FRK I've been reading your posts and I'm not clear on what your problem is. If you are saying that when you turn the wheels left and you get 24 degrees on the left wheel and you turn right and get 17 degrees on the right wheel that's a problem that is fixed with linkage adjustments, offsetting the center point of he servo, and/or EPA adjustments on the radio. However, if you turn left and get 24 degrees on the left wheel and turn right and get 17 degrees on the same wheel , that may just be the ackerman (turning the inside wheel more in a turn for the tighter turning radius) and is normal. To me anyway, it not clear which of these two situations you are talking about.

But in any case with full travel on the radio (on my radio that's 150 not 100), you should be getting full steering lock or there is something wrong; either something is binding and not preventing the wheels to move freely or perhaps a bad servo. Seems like I remember one screw in the chassis that if you used one that was too long it caused a problem with the steering, you might check that.

Sorry for the late response.
I said that now turning the wheels to the right and left steering I have symmetrical steering. Finally, both wheels turn 24 degree externally and internally max 17 degree max. The arm of the servo saver beats on the steering columns, and limiting these values. I am aware that even affects ackermann, but I wanted to get at least 26 degrees of steering maximum, like many other models ..
I think that removing thickness above the steeringarms and using a shorter arm (of the servo saver), I could have more maximum angle.
How thick you have over the steering arms ? And how long is the servo lever from hole to hole?

the linkage from servo horn to steering bell crank. I measured the gap between ball cups 11.5 mm. I have 27 degrees left and right on the setup station.

Using a shorter servo saver would limit overall travel.

I just set my limits in the radio, do some circles, adjust till even and run it.

I think you're overthinking things a little.

Personally I think the TCXX was ahead of its time and with the update kit it's just as capable as anything out there. I have no problem keeping up.

Any deficiencies in my lap times I wouldn't blame on the car

I also run an aluminum chassis plate which seemed to really help out.

+1 I was able to get my tcxx better than my ARC last saturday at TQ raceway. I don't have the upgrade kit on my TCXX. Actually my tcxx with 17.5 kept up in the infield with my friend's ARC with a 13.5

Damn good car.

Few used ones available, I bought all 3 I've seen listed in the past year. The update kit could be ordered I believe.

Yea right 350.00 for any updated parts on top of trying to find a used chassis. That's crazy to me! Your 200.00 bucks away from a A700 or even a new xray,yokomo!

I do agree it's pretty expensive for the update kit. Really, all of the high dollar parts are included in the update.
New chasssis, motor mount, shocks and towers, dcj's, floating servo mount.

I could have chosen many other cars, but I like the purple, and have always been a HPI/HB fan.
Plus I like to be different.

HPI should have just come out with a new kit. I don't see many people buying a TCXX knowing that they would then have to put 300 into it for the upgrades to have a current car. The upgrade kit would only appeal to previous owners of the TCXX. New drivers are not going to come onboard.
