Default Spacing a wheel hex

What would the best way be to fill this gap without creating a friction bomb.


This is on my ERBE-gt build and i don't want the wheels to be able to move in and out.

Alternately how can i hold the axle back to here?


Whats going on here is im running a set of HPI hexes on there and it leaves that gap when the axle is seated into the inner bearing. obviously the savage stub axle is shorter.

Used to run this combo, the washer doesnt work with most of my wheels.

Running this now.


But it leaves me with the gap issue. i tried running the hpi flange nut but it leaves the wheel loose as it doesn't drop into the hole like it should as the axial hub fills it.

Shims. Just find a pack with the correct inside diameter. TOP, Yokomo, Tamiya and others do them.

You can make your own shims from popcan aluminum

Something along these lines then? Tamyia part # 53646



They don't list a size though. for $8 i would hope they would be adequate.

For the shim nearest the bearing you don't want it to touch the outside bearing race since this is stationary as opposed to the inner bearing race which rotates. So make sure the OD of the shim is less then the OD of the bearing.
