Subject: Vert Fin
The fin has a nearly half circle filed out of it to accept the boom.
I too , use the 2P (or eq.) for stiffness and lightness.
The boom is not slotted, although, I do taper the right side for the
last 1/2" to allow the pushrod to exit smoothly.
The boom location is marked square to the rudder hinge and
then a 1/4" rat tail file is used to sand out a dead ended slot on
the right hand side until I just break through the left side at the
bottom.
I then glass the left side w/ .75 oz. glass and thin CA. The right
side is glassed the same way, except I force the glass down into
the 1/2 circle. The vert fin is glued on with thick CA after the boom
is attached to the wing. The trick is to mount the wing, turn the
plane until the H. stab is resting on the table edge and glue. This
ensures perfect alignment between wing and tail.
Happy flying.
