Thanks H2O1B. Yep, I think that is the problem too. I tried everything...verified the CG, dive test and the only thing that seemed to work is a TE shim. But, I could hear flutter with the shim so I quickly landed. Might have been because the shim was a ‘field expedient’ thing rather than glued. This plane had some quality control issues from the manufacturer. Three pushrod tubes were glued in the fuselage rather than two. I had quite a time removing the extra tube that flopped around back there. Also the rudder pushrod exit was misaligned. The pushrod was severely binding. This is my first glider and I sure wish I had noticed the stab was misaligned. Thanks for your posts.
