I'm using specr shimms, definitely the way to go. It makes it so much easier and faster to make roll center changes. It's definitely easier than changing block inserts on the 2014 car for this purpose.

Ran the car tonight. Ran into some big issues and dnf'd for the first time in over a year. Servo saver isn't the same one way to the next, and middle of driving steering would give up. At times is be full lock on the radio, and steering would be straight on the car. Radio is a kiy, servo is a savox low profile, tekin esc, ko receiver. I tried swapping servos with a spare savox a friend had, swapped my rx from the wgt car, even swapped power caps and it still was the same. Still glitches. Many think it's the servo. And the saver for sure. Opinions?

Also, noticed the servo mount has a ton of flex and movement on the new rsd chassis. Anyone else have this issue? Countersunk holes too deep and the screws bottom out on the mount?

My center mount fits very tight on the RSD chassis. I did have problems keeping it centered on the stock chassis after a hard hit but it's been good with the RSD.

Does the aluminum part of your servo mount have a nub on both the top and bottom? My original one did not and replacing that with one that does made a big difference.

I think only on the bottom. Not top. How does that make a difference, when it's just that top carbon plate?

What servo are you all using?

Gilbert, are you going out to Full Throttle on Saturday for test and tune day? I am hoping to get out there to try the rx4 out for the first time. I know Shane was happy with his.

On the chassis, have you tried different screws? If you feel that there may be an issue, please take some pics and we can send a replacement with a stamped envelope for you to return the bad one.

On the servo issues, have you tried your radio on other cars? The KIY has issues with the steering pot, so it could be that.

Tested the radio on my wgt many times, no issue. Also checked on the radio for that real time data feedback screen that shows you your channel inputs-no issue.

I'll see if I can take pics. I'm not blaming the chassis at all. Just taking a guess at why the servo mount with servo moves soo much. Screws are definitely tight.

Had a similar problem as you with a savox servo. Turns out the wires inside the servo came undone and was shorting out randomly. Sounds very much like your problem.

The weird thing is I tried 2 servos tonight, 2 caps, and 2 receivers. Right now I am trying to decide what swrvo to run.

That nub is used to center the chassis and servo mount plate. I found that having the nub top and bottom keeps the servo centered better.

I have a savox 1251 fwiw.

I'll be there. Make sure you get 2.5 and 2.3 spring sets no progressives. Shane's was the first version of the chassis which didn't include a new top deck. It may be a little difference as the new chassis move the bulkhead like a 1mm closer together and is a totally new top deck.

Also, I'm unsure about keeping the savox because I hear they are super cheap, power hungry servos. I'm not sure what to use!

Futaba 9551 is a good servo, close to the Savox1251 in specs and they are around $85 most places.

Yeah, I have the RSD carpet spring kit which has the linear spring rates you listed. I actually need to put in a call to RSD as the top deck is binding badley with the layshaft pulleys and cant use the antennae mount with it. I am trying to get out there saturday. I can really use that track/test time.
