Don uses a punch die and a Teflon sheet to make his own thrust washers.
The center of the thrust washer is pierced with a dissecting or insect-mounting pin for
the propeller shaft.
Making Teflon washers
These washers may not be as clean
looking as the die-cut ones, but they
work just fine. If you drop one or two, it’s
no big deal; just make some more.

I want to remind those who have a
contest and would like it mentioned in
this column that the deadline for the
“Indoor Free Flight” column is three

That means I need your information at
least four months ahead of time for it to
appear in print approximately the time
of your event—or seven months before
the scheduled contest if you want people
to have some time to prepare for your
The “Indoor Free Flight” column is
published in the January, April, July, and
October issues each year, so the sooner
you send me the material, the sooner I
can get it into the column.
Until next time, keep the weights down
and the times up!
