In the interest of lightness I'm hollowing out the back side of the triangle stock I'm using....every bit counts, especially at the back of the plane. I don't think tail heavy will be an issue as the original was not tail heavy. Never mind the hunk of iron hanging up front (Enya 90 4C). New tail fin will be a built up affair as will the horizontal stab. Both are near solid hunks of 3/8 balsa. All the tail parts will get an airfoil shape of some kind to help reduce weight and hopefully help reduce the tendency to flutter. They will also get sheeted to increase strength and I will gladly accept the small weight penalty. Don't bust me for this but everything will be glass and epoxy. Way back in my 1/4 Midget days I could build a plane (all wood), glass it, paint it and still come out under the minimum weight limit. I will be trying pull/pull on the rudder for the first time and I'm not sure what I'm doing on the elevators. The original had a single push rod (balsa) with a fork at the back for each elevator. I'm not fond of the setup but maybe it will be "good enough" with a carbon push rod.
