First I thought it was my servo allluminium horn, that was the problem, but changing it didn't make any diffrent. Changing the servo also didn't help anything.
I looked very careful at the link between the servo horn and the steering rack, but this does not change lenght at all. (I measured it, and checked it several times)

So my own thought goes to the floating servo mount. I think that it moves a little when the car has a small impact. I have tried to tighten the 2 screws in the chassie, but It seems that I can't get the so tight, so the servo mount is completly fixed.

On my previus Xray, there was a smalle guiding pin located in between the 2 fixing screws, just to hold it in place, but on the EVO700, there is only the 2 screws.

Does any has some other idears, or has anyone had the same issue with the floating servo mount.

Thanks in advance.
Are you using a solid aluminum servo horn? I would suggest the xray 4 spring servo saver if you're on a track that uses clik-trak barriers or you hit things.

the actual servo moves because the holes in the servo case are bigger than a screw. Square and KO make some collars that are the size of the hole in the servo case that really help.

Of course best of all is the all in one, no mount needed awesomatix servo.....

I had the same issue and it was the floating servo mount. With the narrow chassis the mount hangs over more, so if you hit a dot or something else it will move a little. I Went back to the standard L chassis, no more issues.

It's not the servo there are moving in the floating servo mount i'am sure. It's more likely the servomount there are moving on the chassie.

Please do not hesitate to tighten the mounting screws for AM24 more tighter.
Our team drivers have destroyed a lot of the heavy duty plastic servo arms at crashes but didn't had the problem of the servo mount moving at the proper AM24 screwing.
We use the extra strong 7075 T6 alloy for AM24 and all others our alloy parts and this material allows much more tight screwing compare to the softer alloy parts of others brands.

A trick proposed by Oleg, is to scratch a bit the surface of the chassis and the servo holder where they attach. You substantially increase the friction between the two parts and I swear the servo will not move one bit.

Thank you, I have been hesitating to over tighten the screws as I was afraid to strip something.
I will tighten harder, and see if the screw then brake

On the Standard EVO can I run the alloy chassis without the long centre line brace? I think its called the AM30

Thanks Michael

I think Oleg had said not to run any of the alloy chassis without an AM3x brace installed. You'll end up bending the chassis.
