Default When to replace a chassis?

I have a RC8 that has about a year or so on the chassis, but not sure if it is ready to be replaced. It has its wear marks on the bottom but not bent. Im going thru the car and replacing all my worn out parts and kinda doing an update to match the RC8B mainly the towers and radio tray and the hinge pin plates. Whats yall's opinion?

I don't pay attention to how many scratches it has on the bottom, as the other person said some sponsered drivers drive them like that.

What I would do is tear down the buggy until you have the bear chassis, then place it on a flat surface to make sure it isn't tweaked (bent, cracked etc...), then I will look at the Down stops (Droop points) and make sure there is still reasonable material left for it to work properly. if not then replace, if your chassis is still reasonable then Roost-on

Thanks for the input!!!

The chassis is not completly silver on the bottom mainly on the kickup points of the chassis. So i will run it a little longer prolly untill the first of the next year.

We run chassis' until the back is thin. Generally to about 1.5mm unless as menioned that during a rebuild you find that it's bent or the droop screw areas are deeply worn.

Is the chassis suppose to have a bow in it to help for flex? I checked mine on a flat surface and it has a slight bow up in the middle,is this normal?

Depends, I will change my chassis at the end of the season - if I plan on keeping the chassis for the next season. i personally just think that these 1/8 go through a lot of abuse and I just think that all the pressure and stress that is put on the chassis, it becomes weaker.

The chassis should be flat but a little bow from front to rear isnt gonna make a huge difference but if it twists your going to probably have some issues.

I ran my last RC8 chassis down to 1mm in the rear and replaced it. I bought a rtr chassis for $45 but next time I think I am gonna get a BCE chassis because I have been told they last a lot longer.

I refuse to use a skid plate. I think they screw the cars handling up. Every time I see a car bucking really bad in back they are running a skid plate.
