Being a bit picky tonight, too Yes, there is.... a centimeter of fuel tubing on the axle does the trick. That's what I did on my Scorcher when it was new

The RCH nylon A-arms also have those cavities, and on the RCH arms they are obviously made for bearings,



as they even had some special collars (RCH #729 Axle Collars) to keep the bearings in place.

Mine too has the special collars for the bearings.

What wheels do those hubs fit?

They fit the standard SRB wheels.

Thanks guys ! I ended the chassis. I just now need a rear arm and tires I found all I need in the mess. MSC are too expensive and this scorcher will be on the shelf. The arm I need has just 1 cavity for the bearing.
Tomorrow, I will post some picts.
Your help was impressive and amazing. It was only a rebuilding but now I have SRB chassis .
Thank you very much to everyone.

I have a Super Champ Arm only I could be interested int that chassis and bumper if your going to move it on?

That's exactly the arm I need. Ho much? Please.
I don't know yet for the black chassis. I have to see if I can build another chassis or not. But I think that it will be sold in à Job lot.

My only point was that Tamiya never intended the recess to be for a bearing.

That does look like a mk2 arm, not a Super Champ arm.
