A CL Scale model that was more than
More than 20 years passed before Frank Beatty completed his Eaglerock CL Scale model.
When he started the project, his primary
references were three-views from
1953, but little more was available for
documentation. He put the project aside
for future research.
In 1973, Frank came across photos
and text in EAA’s Sport Aviation and
Vintage Airplane magazines that featured
the Antique Grand Champion full-scale
Eaglerock. He also added a book about
Alexander Eaglerock and cockpit photos
to his growing documentation.
Frank’s model was built to an odd
scale—11/3 inches to the foot—so that
31/8-inch-diameter Williams Brothers
wheels or Milman spoked wheels would
be the exact scale. Its construction was
built up, with the model broken down
into many subassemblies.
The jigs, strut locator blocks with
predrilled pilot holes, and lower wing
spar alignment boxes were used to
temporarily locate and align the wings
while the struts were built into place.
The assembly was then taken apart for
covering, finishing, and detailing, and
then reassembled to proper alignment.
The undercarriage and tail surfaces
were built first, followed by the fuselage,
cockpit, cowlings, wings, and assembly.
Frank used platforms for mounting
dummy pilots in the cockpits, but
detaikled cockpits for Precision Scale
could be installed.
The model’s main areas were covered
with silk; the cowling, struts, and other
solid and sheet-covered areas were
fiberglassed. Equal parts of AeroGloss
Corsair Blue and AeroGloss Curtiss Blue
were mixed for a shade resembling the
full-scale airplane. AeroGloss dope was
Black registration numbers were made
from Simair Frisket Film. The logos were
marked on glass, covered with dope,
peeled off, and added to the model with
Elmer’s Glue and dope. Frank added
many details, including leather cockpit
openings, wingtip and rudder lights, and
a non-flying, decorative propeller from
plies of Swiss pear and basswood.
