If i do this i will let everyone know how it goes. If any of you have opinions or ideas on this method please post them.
Can you measure the thickness of the chassis under the trans? just interested if yours is thicker than my caved in piece. Which measured 0.4mm.

Depending on what Kyosho do with my chassis I sent,I will most likely make a piece of plastic to take up the void.

Pathetic excuse for OCD. Having OCD is knowing the chassis may or may not cave in even if it's hidden behind a skid plate, and taking off the plate every now and again to check. Head in the sand syndrome, but not OCD!

P.s. K need to issue a revised transmission tree that fits.

As for some company making stuff for the skid, I would rather get an oem fix from Kyosho themselves. Else the company line would be buy so and so part .

No offense but how many pages are we going to have on 2-3 people that have had dents in their chassis?

I am ready to unsubscribe for a few weeks then come back.

Oh my god. The horse is dead.

So then a plastic shim would do the trick.

does this dent hinder performance? my chassis has had a bunch of slap downs and i don't see any dent forming. My thought is that if it did start to dent, so what. if the rest of the chassis isn't twisted,..... so?
