RE: Sig LT-40 Build
Somegeek,
I don't want to come off as being overcritical because you have done such a great job on this plane, but by looking at your pictures I can see that you may have overtightened the screws mounting the servos in. I can see the rubber grommets "puckered" in. You want to screw them in to just the top of the rubber, when you over tighten them the screw pushes down to the metal insert. When that happens it bypasses the rubber material and vibrations will pass directly to the servos which can destroy a servo. You want the rubber material to absorb vibrations. Take a look at the attached diagram.
Hope this helps
Ken
