Thanks for that info!

I will double check the RPM site but from what it showed they only have the caster blocks for the E versions of this model.

I like the idea of the boiling and I will do that when the replacements arrive. For now, I repaired the broken caster with a ****e load of super glue and should hold for tuning runs on pavement. I am still working that whole situation out after getting Sidewinder fuel. The came with half a quart of the Traxxas stuff but Sidewinder is all I had close to me so I am working that out...
