I have been asked a few times lately about the proper way to install a servo into your aircraft utilizing the grommets and brass eyelets. A lot of people don't actually know and there isn't much documentation on the proper installation procedure so I am going to detail it here.
It's actually very simple, the grommets only install one way into the servo, it's the brass eyelet that you need to be concerned with. For most standard installations, the servo mounting rails will be installed above the mounting surface. The brass eyelets have a small flange on them, this flange is what needs to face into the mounting surface.
The reason you want the flange in the eyelet to face the mounting surface is so that it does not crush the mounting surface when you tighten the screw down. The wide flange spreads the load out, you always want the flange to face the mounting surface.
When you tighten the screw down, you don't want to crank the screw down. There is 2 reasons for this:
1. You don't want to crush the surface the brass eyelet presses into and possibly compromise the mounting surface.
2. You don't want to strip out the hole the screw threads into.
All you need is for the screw to pinch down on the rubber grommet, this will compress the grommet slightly and force it to squeeze both down onto the brass eyelet and squeeze out onto the servo mounting rails. This is plenty sufficient for both small aircraft all the way up to giant scale airplanes

Edge V3 Vid. End of her second indoor season and still has a crisp feel. Tons of crashes and excitement with this plane over the years. Check out the flying. Fly Twisted my friends

Just editing up the indoor vids from a couple weeks ago and more is on the way. These are the super-lite planes from Twisted Hobbys. When it's calm outside, they are a blast outdoors as well. The thumbnail is a little 3D Line joke from Nall a few years back.
Hope you enjoy this one
