O.K., now I'm REALLY confused.
1. Bob, just HOW are your tailplanes loose? fore/aft? side/side?
rotationally?
2. Graham, it seems to me that the TP14 pins in both TP9 and TP12 serve to
transfer the
torques from the pitch pushrod to the tailplanes, so they both have to
be precisely
fit. And therefore additional bearing surface would help. Unless
there's a bit of slop
between TP12's I.D. and the tailplane torque tube's O.D.
Am I missing something?
