Made a start on the aileron to show scale hinging. The drawings show brass tube bearing with piano wire hinge pin.I've used this method before and vowed to never use it again as they went very sloppy guickly.
So any of you engineers have a better solution please let me know.

Depending on rod diameter, would Sullivan outer snake casing be any good as a bushing. Just a thought. :huh:

As you may know Glens models hinges are similar. They use large diameter brass tube - It doesn't get sloppy but it migrates.
I think plastic bushes & piano wire is the way to go. An equivalent to the old micro mold snakes made for bowden cable inners would make a good bearing material.
My Decathlon (which i will have at Cashmoor tomorrow) uses 3mm carbon rod on ply hinges.

Forgot to say I'm going to use 3mm carbon rod for the hinge pin so the snake outer will have to fit that

What about very small shielded ballraces - the type fitted into some of the small brushless motors could work.
