UMX Yak WAGGLE!
After lots of flights on my Yak, it seems to be "wagglin" at higher speeds.....its intermittent, and doesnt seem to do it so much at a medium cruise speed...at first i thought it was just the rudder, but it appears it may be a combination of the rudder and elevator. I checked the linkages for play, thought maybe it was "flutter", but everything is nice and tight, so now im wondering if maybe the 3ASX system (which i love!) is slowly going bad....has anyone else had this issue? Thanks! Bill
