148 MODEL AVIATION
FREE FLIGHT MODELERS, like their
flying sites, are spread far and wide. Many
of us toil away in relative isolation,
meeting with other fliers only at contests.
Through the years we have developed a
number of ways to stay in touch, share our
knowledge, and pass along our passion for
the sport.
Perhaps the first to do so was Frank
Zaic; his series of Model Aeronautic Year
Books kept modelers around the world
informed from the 1930s through the
1960s. Frank, who turned 90 last fall, was
honored recently by the Fédération
Aéronautique Internationale, which is the
world governing body for sporting
aviation.
The organization presented him with
the Gold Medal for Aeromodeling: its
highest award for model aviation. Frank’s
familiar orange Year Books are still
available from a number of sources,
including the AMA bookstore.
Today we have a wide variety of
choices ranging from columns, such as
this one, in general modeling publications
to specialized Free Flight magazines and
newsletters. If you are interested in Free
Flight, the best way to stay informed is to
subscribe to one or more of these
publications.
The National Free Flight Society’s
(NFFS) digest Free Flight comes out 10
times a year. In it you will find articles on
a wide range of topics, contest reports, and
often full-size plans for a small model. The
only way to subscribe is to join NFFS.
For information about NFFS
membership, contact Hank Nystrom at the
NFFS Membership Office, 3317 Pine
Timbers Dr., Johnson City TN 37604. You
can also E-mail him at [email protected] or
visit the NFFS Web Site at
www.freeflight.org. Membership for US
residents 19 and older is $39 for two years.
Indoor News and Views (INAV) is a
bimonthly publication for Indoor Free
Flight duration fliers. The issues I’ve seen
include many construction tips, threeviews,
and contest reports. Although the
focus is on the high-performance duration
events, there is also a Scale column.
A subscription in the US is $15 a year.
For information, contact Tim Goldstein,
INAV subscriptions editor, at 13096 W.

Electronic News (SEN) site at

In addition to the monthly and

simple-to-build torque meters—one for
smaller models with a range of 0 to 40
ounce-inches and a larger one with a range
of 0 to 130 ounce-inches.
For the Power fliers, Dave Clarkson
explores the advantages of using flatbottomed
wing airfoils for Slow Open
Power, which is the British equivalent of
our new Classic Gas event. For
undercambered ribs, Martin Dilly suggests
laminating the ribs from thin sheet balsa,
sanding to shape, then capping the top and
bottom with unidirectional carbon fiber
and epoxy. After everything cures, the
individual ribs are sliced off, sausagestyle.
Accurate construction is important
whether you are using traditional or
composite materials. Articles by Chris
Edge and Mike Fantham explore various
building fixtures. Most of these are simple
and inexpensive to build, requiring a trip
to the hardware store rather than a fully
