Hi all,

After owning a spark for ~7 months now and seeing same and other models drive a lot. I think there are 2 weakspots on the 6S models.

TC already released the new CVD design, so i copied the idea to be able to upgrade the old CVD's.

Second problem is the hex's being rather deep. Certainly all aftermarket wheels, but even the originals tend to lose pins like crazy as they aren't fully locked in by the wheel hex.

A 3mm tight fit ring solves the problem: ( I haven't lost pins ever since i started using it)

Even on the Kagama it fits perfect:

If anyone is interested <the STL files are shared below>.

I ended up making new pins for my CVD that are mated perfectly for the CVD then adding the spring style holders then covered with shrink wrap. Since I’ve done that so far haven’t lost a CVD pin the factory ones are just a little short allowing some play that I’ve lost several pins

Definitely like the shim unfortunately I don’t print the collar looks great also I don’t wonder what type of material you’re using. Just on my RC jet landing gear supports the ones I’ve purchased have all cracked so I’ve gone back to making my own from balsa

For track use i just use PLA and replace them if they wear out. For a RC Jet landing gear i would go for TPU or PAHT-CF
 
I should get into printing have a bunch of part upgrades I make but I machine them 3D printing would be much simpler and lighter
 
I’ve played with metals for some years now but some would be a total pain to machine like the CV cups you’ve made
 
Just received my warranty ones they look really good haven’t taken them out yet so I can’t tell if there plastic or aluminum

I can share the STL's as a zip file here I think. I attached it to this post

Today i received my latest TC order, amongst which a new model CVD (for reference) and the maintenance kit to get some old ones back to life.

I have thought about getting one but don’t own a PC or laptop and have so much money into my full sized metal machines hard to pull the plug on a printer and Laptop. I love the anodized red mine are black which is cool also, with mine I will probably keep until my modified ones fail

Yes please to your STL files .Thank you
 
Rotaqu’s cvd rings work better than the metal corally ones because they have a slight interference fit. No gluing needed and that makes service that much easier.
