I tightend the bolts by hand to make sure they werent over tightend… And trimed them all at the same length.

I was doing quite a bit offroad riding last week when i was on holiday lots of beach and hard trails with the 225mm wheels. Can’t remember seeing the damage with quite a few weeks of riding the 165mm wheels…

Maybe bearing wheel spacer needed on those offset rims to kill the slop created by hard offroad riding

It has a bearing wheel spacer. Comes with the kit

Is it nice and tight or loose fit? Does your outer bearing ride on the threads only?

#306

That’s some crazy wear. My setup is in the outer holes and it doesn’t have any wear like that

I think there is a V2 of the star piece in dev so maybe not too worrying

Any chance you have pics of it all set up before you took it apart?

#307

This is why I check my shit b4 every ride

I think @Deimos deserves a free set of these if they exist.

I’m sure Kevin will take care of him

However, I don’t know if they’ve been manufactured yet

I want @Deimos to get a set to do an A-B test of the two designs.

maybe it was caused by the wheels getting some air time with the throttle on, and then when they touch the ground again the stress went directly to the plate

better than broken/seized gears i guess

#313

Maybe? Yeah I agree. I’ve jumped mine around quite a bit though and it hasn’t done that yet. I should check though to be sure

#314

This is plausible but it would have to bend all five bolts in order to rotate. Most stresses should go to the bearings and axle. Bad tolerances there could lead to stress at the wheel adapter

#315

@Boardnamics ETA on Hypertruck adapters?

#316

those will exist? :eyes:

A typical crash mode for a funwheel is to topple side over side, and so that means if this crashed it would likely be rolling on the motor cans themselves in a possibly very destructive manner.
