Ok, that tire machine mod is a hoot. I don't need it...but I want it. :dance:

It would be easy to make for a guy like you. You need it if you true tires. It takes the sore neck out of tire truing!

Great tutorial Bruce!
:D

No one uses silicones on the tracks I run on so Im not sure if this would work or not. It works with rubber and urethanes tyres. Try running "air" rims at the rear. Grind away most of the central hump on the rim. Just leave about 0.5mm of the hump in place. Just enough to locate the tyres. Then drill about four 1/8" holes around the rim so that the holes allow air to access the cavity in the rim you've just made. You now have an "air" rim ala NSR. Glue tyre as you would normally but only around the outer edges. Now true tyres as you would normally do. Works a treat on rubber and urethane. Not sure about silicones as I've never used them. You might see an improvement even with silicones.

Very good info Bruce, I never would have thought to fill the divot in the wheel. I might add that Carrera is notorious for side play in both axles. Cutting spacers out of plastic and then cutting a slit in them to fit them over the axle is another easy fix.

I also love the add on for the truer. I'm gonna have to study your video. Is that just a long arm that's attached to the motor? Is that the only reduction?

Yes, the shims. I shim mine. We sell them here.

If I can remember, I'll take more photos of the truer. The arms are RC suspension parts.
