I see what you mean, BP. Like the bushings on Twinforce suspension arms, for example.
I had the same idea, and made my delrin bushings like this (with a "curve" in the middle) but so far the straight PP bushings held up fine.

The flextek guys must have had a similar idea, they just made their bushings shorter (only like 3/4 into the actual arm) to get the same effect.

Anyway, I have the feeling my arms don't flex much, or not at all, during normal running. I think they only flex under hard impacts.

If I were to make new ones, when my PP or Delrin or PTFE ones fail, I'd do them as you described again, but with brass.

Another update on the truck: Last week I got some parts, and now I can replace the pre-production prototypes of the 1/8 diff cases with the final product! Yay! And I re-wired my ESC, now it's definitely picture-worthy, as it looks nice and clean.

later, guys
