Here we go again - Nir, my friend, a jet builder, a jet flyer, and my jet trainer, came by the shop to view the Avenger. He loved it all especially the construction and paint scheme, however, he did not like the rudder pull/pull servo arm connection. He clearly showed me the anticipated rudder movement - thus flutter based on the sloppiness of my homemade servo arm setup. The setup provided far toooooo much sloop in the rudder which is an invitation to major FLUTTER. He was able to tap the rudder and get far toooo much movement before the cables locked in the movement. So I am now removing the rudder and rewiring the pull/pull cable and using a 2" SWB servo arm. Removing the rudder to attach new cable involves digging into the top of the rudder where the hinge point wire sits. It then needs to be pulled out (over 12") to release the rudder from the fin. O'well, better to get it right. Chic
