The problem with the original fitting
orientation is that it loads the flat strap
material in a bending moment instead of
tension.
Flat strap likes tension best.

Kirk,
I never used or heard of Earl Myers drawings but I used the following:
Piano hinge MS20257P5: ASS p/n 03-00051-6 2
Two lug anchor nuts AN 366F-1032A in the wing 24
Two lug anchor nuts MK1000-03 in the aileron 24
And plain machine screws AN526-1032-R18 48
Machine screw and anchor nut about every 6 " without interfering with ribs.
The machine screws are not countersunk but are offset against each other so
the heads do hit.
When flying I observed the aileron, a 1/2" deflection (trailing edge) is
enough to start a gentle roll in to the turn.
I am sure during landing it deflects more (lower speed) but it does not
take a whole lot.
Anyway the control stick hits it's limits (torque tube control arm hitting
the floor board) before the aileron.

Hans,
Why did you use two different types of anchor nuts?

I started of with using the nylock type (AN 366F-1032A) only.
But these are to big on the aileron side, they would show through the
fabric, same goes for machine screw length.
This happens because the Aileron nuts are mounted on an angle, 30 degrees
or so.
You can of course mount them lower but that is also away from the hinge
point and makes the setup weaker.
If the explanation is not entirely clear maybe this drawing explains
better.
(See attached file: Visio-Drawing1.pdf)
Best regards

What program did you draw this picture in? It says Visio-Drawing1. It looks
good and easy.
