There's a 3racing brand "wheel stopper" over on rcmarket.com.hk

I couldn't find the Tamiya part anywhere either.

Thanks guys, I was hoping to find somewhere in the US, but I ordered from
rcmarket as suggested.

Thanks guys.

That's the problem with the Tamiya parts. Seems like when you put an alu nut on the alu wheelstopper the parts destroy each other becouse of the same material softness (problem is as old as the first F103, so +15 years). Use a steel nut or put some grease on the treadz like mentioned in the F104 manual. Best off all is to use Qteq stoppers with a hollow titanium axle (of course not TCS legal). Those parts are lighter, stronger, better centered (and keep dust out better on diff side)and more expensive:

Slick setup.

Or you could just order this part, it is a 103 part number, but identical to the 104, and it comes with the diff side for a 103

MSRP: $9.50

and it is in stock at TA

The 103 diff is quite different in how the wheel bolts on on the diff side from the 104.

Do you know if these are in steel or aluminum?

Sydewynder

I think he broke the left side. 103 and 104 should be the same. You're right that the diff side are different.

It's not that they're Tamiya parts, it's a simple matter of similar materials. The same could happen with a stainless axle coupled with a stainless nut, etc. Either use dissimilar materials or lightly grease the threads (AW grease works well).

Fortunately I've never had a problem with this...bent axles yes but never a broken wheel hub in all the time I've been racing Tamiya F1 cars starting with the F102

Im probably jinxing myself here, but I too have never had an issue with this.
and the part# i referenced is aluminum.
I just got 2 in to put a couple of 103"s back together

InspGadgt

My understanding is that it is with certain similar metals like aluminum with aluminum...since aluminum oxidizes that seizes the metals together...likewise with titanium...but steel on steel shouldn't. Or so I've been told.

Maybe a dumb question here but....Has anyone tried using one of the mini 2s lipos in the F104? I would think you could get some handling benefits by moving the battery forward or back. Some sort of brace would have to be made but I'm sure it could be done.

Aluminum can indeed oxidize, but anodizing does a good job of preventing that.

The culprit here is an effect called galling.
