Default wheels spinning on hex drives

Don't know if this has been discussed before but advise is needed please. I am running the new tamiya evo 6 on carpet with 17.5 blinky. Car is pretty much standard set up and have been running it for about 6-8 weeks. Issue I have found with it is the front wheels are starting to spin on the hex drives. I'm running sorex 32 any ideas?

Could be a couple of things. Either the hex on the rim is not sized correctly or the rim plastic is too soft and allowing the hex to move.

Get new wheel nuts. Preferably the serrated type.

Cheers guys. Car has serrated wheel nuts already on but have just ordered some more just to be safe. Maybe it's a bum set of wheels, although the rears are fine, will try some new wheels as well.

most sedan wheels have a significant overlap with the hex drive. it seems hard to imagine the wheel slipping without there being obvious damage.

but if the rears are ok, then try switching front to rear and verify it is the wheel. are you certain that the hex drive is not slipping on the drive axle?

If you're using wheel track spacers replace them with wider hexes...

Yes , absolutely.

I think this is gunjack's problem in the first place. You have to use wider wheel hex if wheel spacer is thicker than 1.5 mm.

I find this can be common with a spool, especially on high grip carpet. Tighten the front wheel nuts really tight.

Have been using 5mm hex with the 1mm spacer. Will try without the 1mm spacer.

Yes, it's common sense .... if you measure the depth of hex inside sorex rims , is only 3.6mm depth.
