I had a rudder flutter problem if I didn't keep constant pressure on the rudder pedals. After many years of experimenting I tried doubling heavy springs. It worked. No more flutter. There is no increase in rudder pedal resistance because the springs neutralize their force equally. Can fly with feet on the deck without rudder flutter. john h mkIII Titus, Alabama -----Original Message----- From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of Gary Aman Sent: Tuesday, November 19, 2019 8:33 AM Subject: Re: Kolb-List: Re: Different tail feathers for a Twinstar MK II??
