Thanks for the input gentlemen, I truly appreciate it. I made the choice to go without grommets a year ago when I was rigging my first turbine model. My reasoning at the time was that turbine models are typically very fast, and fast models are prone to flutter. There are lots of "tricks" to prevent flutter, but the best way (barring counterbalancing) is to eliminate slop and springiness in the linkage. To me, servos properly mounted with grommets and eyelets seem fairly easy to wiggle back and forth a tiny amount - a perfect foothold for flutter. There's no engine vibration, so it seemed like a good idea to eliminate the grommets and firm up the control linkages. So far, everthing's working great - even the Hitec digitals

I do see the argument about the bumps of taxiing and landing. However, it's a different kind of "jolt" than the millions of tiny vibrations that a servo would see from a typical glow model. Do the grommets absorb the jolt of taxiing across a crack in the pavement? I really don't know for sure, but they certainly wouldn't hurt.

Even though I went without grommets, I'm not entirely comfortable with it and don't know that I would recommend it to others. That's why I wanted to find out if the jet community had settled on a common practice.
