Task: Continued work on the trim tab. It's
a real beast!
by clecoing the hinge to the trim tab, then marking the top
hinge 3/8" in from the outboard edge so it could be lined
up with the holes in the elevator. I used a cleco clamp on
the inboard edge to hold the hinge in place. I then used a
long straight piece of aluminum angle to position the trim
tab trailing edge even with the elevators trailing edge. After
quite a bit of checking and rechecking, I drilled three holes
through the elevator skin, trim spar (E-606PP) and into the
hinge. I put clecos in the holes, removed the cleco clamp
from the inboard edge, and rechecked trailing edge alignment.
Everything stayed put from the drilling.
Here is the trim
tab with all the holes drilled through the forward half of
A close-up of the inboard edge.
I then set the rivets
along the forward top edge of the trim tab.
Last was drilling the three inboard rivet holes
to #30, countersinking, and setting CS4-4 pulled rivets.
then moved on to the trim servo cover plate. I marked inboard
from the upper edge 3/8" and over from the left side
1-1/4". The other line is 1/8" to the right of the
first line. You'll see why below.
Notice the servo control arm is not centered using the lines
marked per the plans.
Here is the servo aligned with the second line I drew 1/8"
to the right of the line the plans call for. This looks much
better. I'm going to mount the trim tab and hook up the control
rob before drilling these holes for the servo.
