Elevator and Trim Tab Construction
During this period, my web page updating became got kind of...well,
cancelled. Too many things going on

The elevator wasn't too bad to work on, it just had a bunch of
parts. The disappointing thing is seeing the dings you can make
for each mistake made. Hopefully with a little filler and work
during painting time everything will look real good. To prevent
problems during building, I think the best advice is to go slow and
thoroughly think about the physics behind each pound when you grab the
rivet gun. If you don't have that gun centered over the spar, or
matierial underneath and it starts to hammer a little off-center, it's
gonna leave a ding. Things like that can really get to you when
it starts out looking so good, but then you ding it. All in all
though, it's looking pretty nice, and there is a good collection of
finished parts growing in my basement. Tailcone starts next, and
I think I've changed my mind and decided to assemble the tailcone and
other parts when done. It'll be cool to have a big huge piece
