To add to Rob's comment, I like to tear down the control system on my DLGs every couple hundred or so launches. I didn't do this in the past, but the more I fly, the pickier I get about it. I find that as time goes on, launch height and crispness of control on launch goes away sometimes slowly and imperceptibly. If you get to the point of flutter, you have WAY too much play. Any play will rob you of launch height and especially camber effectiveness way before the flutter is noticed.
Pushrods can get fatigued also. They're cheap and fairly easy to change, so why not swap them out when things get a bit sloppy? It beats the heck out of replacing a $400 DLG that blew up on launch. If you launch hard, check for delams often around hingelines and don't tolerate any control slop. It will eventually ruin your day.
