Doug,

This is an absolute "don't kill yourself" conversation.  My flaps open up to
between 3/16 and 1/4" in the full down position.  I have seen much bigger
openings.  My plane flys fine dirty with the above gaps.

If you must make show quality gaps (and many have spent the hours doing
this) I'd recommend several (4-5) thin flox beams gapped with the flaps in
several positions.  Just put a 1/16+" thick release gap strip ( I like steel
personally) between the skin and flap and pack the gap with flox.
Thereafter, I'd fill between the beams with micro and sand to shape with the
long board sander.  Keep the flox as your basis height.  This is way more
work than necessary in my opinion.

The alternative to feeling good about one's flap gaps is to leave them up at
the show.  I am quite tolerant of that infinitesimal feeling of shame as I
raise them.  This feeling get's rapidly overcome by sadness for my fellow
builders who are stuck head scratching.

Keep Building!  There are bigger headaches to come!

Although I do enjoy both, Flying is slightly more fun than building.

LN 360 MKII, outback flaps:

- the manual calls for a 1/16" gap between the upper trailing wing skin and
the upper flap leading edge (Having fun yet..?) in the faired position.  It
then says that the gap is allowed to "get dirty"  (language I can
understand) when the flap is lowered.  How dirty is dirty?  Pretty tough
trying to maintain 1/16"...  Any suggestions are appreciated.

Thanks
Doug
