CL Scale Nats
by Fred Cronenwett
This year’s Scale Nats, held July 11-12, was one for the record books. There was a large
number of entries and it was the first
Nats to qualify pilots for October’s
National Association of Scale
Aeromodelers (NASA) Scale Classic.
There was a surge of 1/2A Scale models flown and the number of entries was
up in every event except Team Scale. Because the new CL Scale rules have been
adopted, 1/2A Scale will become an official event in 2015.
We started off with great weather on Friday for the static judging and everyone
hoped it would last, but the weather was not in our favor and we were only able
to get one round of flying in on Saturday morning. The 1/2A Scale competitors
had to finish their flights on Sunday morning under marginal conditions. The skies
were dark, and although it never rained, it was windy on Saturday afternoon and
With 10 pilots in 1/2A
Scale, there was some serious
competition. Bob Whitney,
who placed first at the Brodak
2014 column), flew the same model to a first-place finish at the Nats. Bob’s Pond
Racer flew 10 level laps and handled the wind well.
Ron Duly brought his Heinkel He 111Z that has no less than five .049 engines.
Ron took second place. This model was first flown in 1976 at a 1/2A contest in
California. The top six static scores ranged from 68 to 70. 5 points, which meant
that the flight score determined the
winner. Bill Avera placed third and
earned the highest static award.
F4B, which will be replaced with
Authentic Scale when the new CL
Scale rules are adopted in 2015, was
contested for the last time. Dave Platt
flew an impressive electric-powered
OV-1D Mohawk and earned the top
static score (958.50 points) and first
Ed Mason flew his 77-inch wingspan
B- 17, built from a Royal kit, to a
second-place finish. Charlie Bauer was
third with his Bristol M. 1 Monoplane
Frank Beatty, with 951.15 static
points, was close to the top in static
and earned fourth place. Another new
model flown was Allen Goff’s C-182,
with a fifth-place finish.
Sport Scale had 10 entries and eight
of the 10 scored a 94 or higher in
static judging. The level of detail and
craftsmanship was raised in preparation
for the NASA Scale Classic. Three of
the models with high static scores had
technical difficulties and did not fly on
Saturday morning. With only a four-point difference between the remaining
five models with high static scores, the
flight score determined who would
John Brodak, with a 97.0 static score
and a 90. 25 flight score, was the winner.
Ed Mason took second place with his
Kyosho DC- 6 aircraft, powered with
O.S. 25 glow engines and three-line
