Welcome back to the “RC Giants” column. Well, they’re fi nally here, the
dog days of summer. I hope your winter modeling projects have been
successfully completed and you’re in the midst of a great fl ying season.
Plan to attend a local fl ying event. You’ll see old friends and great models, and
more than likely there will be freshly barbecued burgers available! fi ngertips. No more excessive fl exing of
the wings trying to lift your model at the
wingtips.
“Built-in stops on the cradles limit the
travel so you can balance your model
‘Hands Free’ without fear of it tipping
over or sliding off the balancer. No more
‘guessing’ where to put your battery
packs or weights. You can move them
back and forth until you achieve perfect
balance. It will accommodate up to
18-inch-wide fuselages.”
Additionally, Southwest Systems
offers “Super Size” and “Monster Size”
kits that extend the height of the
balancer to accommodate even larger
models. All of the parts are cut out
from aircraft-grade aluminum using
high-pressure water cutting. The parts
are deburred and prepared for surface
anodizing, which keeps them looking
good for a long time. Lastly, all the
Southwest Systems kits are 100% made
in America.
For more information about the EZ
Balancer II, please visit the Southwest
Systems website, listed in “Sources.”
The Fieseler Storch
Sal Iasilli from East Norwich, New
York, recently completed an impressive
1/4-scale Vogelsang Aeroscale Fieseler
Fi 156 Storch. The model spans nearly
140 inches, weighs 32 pounds, and is
powered by a DA-50 gas engine. The kit
was designed by Paolo Severin of Italy
and imported by Vogelsang.
The fuselage is welded stainlesssteel
tubing. The rest is built-up light
plywood and balsa. The fi nish is Solartex
covering and RustOleum satin white
paint.
“After the maiden fl ight and multiple
control adjustments and trim changes,”
Sal reported, “the second fl ight turned
out to be spectacular! Takeoff was
exactly like the full-scale Fiesler—almost
45° with half throttle and liftoff in less
than 6 feet!
“After fl ying a few minutes, I felt very
comfortable with the control response.
As for the landing, I have never had a
model fl y this slowly. It was almost like watching a movie in slow motion, and
that’s without the flaps and just a slight
headwind.
“I transported the model on the roof
of my Prius. I had some pretty strange
stares driving along the LIE [Long Island
Expressway] at 70 mph in the HOV
[High Occupancy Vehicle] lane.
“Not wanting to offend anyone, I
covered the swastika on the rudder. I
also didn’t want anyone throwing rocks
at me. The cockpit detail is still not
finished but knowing that the plane flies
this great, I can go full bore with the
scale detail.”
Nice work, Sal, and congratulations on
your first flight.
The Fieseler Storch Fi 156 was
designed in 1935 as a requirement for
a STOL (Short Takeoff and Landing) aircraft. It had a 46-foot wingspan and
full-length fixed slats and fowler-type
flaps that increased the wing area by
18%. One unusual feature was that the ailerons also drooped when the
flaps were extended past 20°. This
gave the aircraft excellent slow-speed
performance.
The demand was so high for this
multirole aircraft that the French firm
of Morane-Saulnier, in occupied France,
was retooled to build the Storch. The
aircraft was made famous by its use
to rescue the deposed and imprisoned
Italian dictator, Benito Mussolini.
It was also involved in the last dogfight
on the Western Front during World
War II. It was forced to land by another
liaison/spotter type aircraft, the Piper
L-4 Grasshopper, after the pilot and
observer in the Grasshopper opened fire
with their .45 caliber pistols, forcing the
Storch to land.
The Fieseler was a large liaison aircraft
with a 46-foot wingspan, compared to
the L-4 at approximately 35 feet. The Fi
156’s engine had nearly four times the
horsepower of the L-4, being rated at
240 horsepower versus 65 horsepower
for the Piper.
Nearly 2,900 Fieseler Storchs were
produced during the war.
That’s all for this month. Fly safely,
enjoy the rest of the summer, see you in
the fall.
