I just noticed that I have some laxity in the control rod to the left rudder on my F18. How much "slop" is tolerable? It's loose at the plastic servo arm (the hole seems too big)......it can't be swapped out without ripping the servo out of it's glued location. I'd rather not do that if I don't have to.

Are jets prone to flutter as much as prop aircraft? (I'd never tolerate that much slop in my extra 330.)

Flutter is more of a problem on Jets due to the increased airflow over the surfaces.
Better to play it safe and fix it now.

Flutter is more prone in jets. Whatever you have to do....FIX IT. No room for errors on these types of planes.

What are yall talking about Flutter is a good thing for those of us who are into "smoking hole fire balls"

Only when you get it.

thanks for the replies. I think I'm starting to see a trend here.....

"smoking hole fire balls" is funny.

Think of flutter problems as increasing with the square of the velocity.

Hi,

Just out of curiousity, what F-18 do you have with glued-in servos?

I have a jetLegend F-22. Bought it used and has had many many flights. I've put on more than two dozen myself. But I am always checking the elevators. I don't get any flutter but just seems they have more slop than I am comfortable with. They aren't mass balanced. I don't know how much force is on them statically but they obviously droop when no power is to the servos. Is it better to hav them statically balanced to neutral from pivot point or is it better to have them unbalanced? It flies nice and everything works fine but with the slop on he elevators always was a concern to me.
