. Correct geometry applied with good quality hardware is far more important that the ''bling'' factor, IMO.

Yes, you are correct on geometry of the throws. I truly don't consider aluminum servo arms and ball links to be "Bling"? I consider them to be a tight rigging on the servo to control surface movement.

And even if you think about using a short metal servo arm , remember that the servo case is made of plastic, and the servo mount in the wing and fuse is not attached in anything ''metal rigid'' either..


The folcrum of the movement isn't on the case. I am not an engineer, but I am sure due to the rigging and gearing of the servo arm, there is minimal stress on the case. I have used metal or aluminum servo mounts on my jets attached to thick plywood or fiber glass.....kind of a not true statement.
