Only one Robart hinge
point was used on the rudder, the lower pivot is a screw. Kevlar
string was used on the rudder, with the end connection made with a loop in the
Kevlar. The knot is multiple square knots secured with a small drop of
thin CA. Wick off the extra quickly with
a paper towel so
it does not run down
the Kevlar and stiifen it. That can make a weak point where the
stiff part meets the flexible part. The
final connection was with small beading wire looped
through twice and twisted. The loops were installed with the radio
operating and the servo arms held in neutral. The loops were tightened evenly
keeping the surface centered. When tension and centering looked good
another loop of wire was put on each
side for redundancy.
The elevator pushrod end method is one I stole from a Peerless
Panther I saw many years ago. The
hole in the covering for the rudder
cable was made with a soldering iron, that melts a strong perimeter on the
hole stopping tears.
Wing centerbolt
installation. This is not on the plan.
