Folks
I am a bit confused about the procedure for attaching the flaps to the
wings. I hope someone can clarify it for me.
First, I am not clear on what exact purpose is served by the flap
setting template, and which surfaces or points are considered critical.
The manual says to make a template and glue it to the wing with bondo.
I made such a template from particle board, but I was unsuccessful in
bonding it with bondo. The board is heavy enough and the contact area
small enough that I can't think how some blobs of bondo is going to
keep it in place while I flip the wing over.
Regarding the alignment, it would seem to me the hinge pivot point
should be positioned such that it is at the center of the flap's
leading edge arc (and the corresponding arc of the wing's closeout) to
ensure smooth flap motion without rubbing the wing's closeout area. If
I am thinking this through correctly, this step could be accomplished
without the use of a template by positioning the flap such that its
bottom surface is aligned to the wing's bottom surface, and then
ensuring a constant gap between the wing and flap from root to tip. I
was thinking of inserting some wooden blocks in the closeout area to
accurately set this gap between the flap and the closeout. Am I missing
something?
