We were having a little "deadband" in our Glasair elevator trim system, where you'd roll the trim wheel an eighth turn with no effect on the trim. 



I made a little video showing the problem and the solution. (After passing this around, another builder reported he had a similar problem, but in his case, the roll pin holes themselves elongated.)



Please see http://members.cox.net/mppalmer and click in the "video of trimbox deadband problem." It's a 30 second WMV file.



Hope this helps,

EEA tech Joe Gautheir felt the factory trim tension was way to taunt and  relaxed my trim wire springs. I have been flying my Glasair that way for  nineteen trouble free years.
