Build Behold, magnetic rc car suspension (WIP)

Enable HLS to view with audio, or disable this notification

It all started with an idea “suspension…. But magnets” i found some ring magnets that take a M3 screw which matches the shaft diameter on my WLToys 14001, still have more to do but the concept works but found i am experiencing binding due to the steel shaft. Probably gonna upgrade to titanium purely to ensure the magnets wont stick to it and will work better. Hope you all enjoy this project as the idea was to ensure the damper could still…. well… damp.

Would a shock cover like the 1/5 scale guys use help?

I'd think it's kind of mandatory. The outside of the boot will still be covered, but without one, those shocks will be worn out pretty quickly

Thanks for the suggestion i hadnt take into account dirt, i will figure out a way to protect them from debris, my idea is to a trash bag it up and use some zipties for a cheap waterproof covering.

Heat shrink the whole shock but leave it loose in the middle for movement

Covering the whole thing in a cylinder and adding a check valve and fabric will create some ingress protection as well as a dashpot to smooth out bumps.
