SAAB J 21A
David's
latest, is a 1/4 Scale design of the SAAB
J21 that was a self-defense fighter from
World War II. This is a unique
twin-boom pusher design that the Swedes
built to maintain their neutrality
during World
War II. Because it's a pusher
design, the airframe works well as an
electric-powered model. It would
be very difficult to cool a combustion
engine and still keep the scale look of
this design. Big thanks to Roy
Maynard who visited the air museum
in Sweden and provided images of all the
scale details for David’s design.
The SAAB J 21 series is
arguably the most iconic
propeller-driven aircraft to ever come
out of Sweden. For the time, they
were a bit underpowered but its
distinctive twin-boom,
rear-engine design was easy to recognize
and its aerial performance was nothing
to scoff at.
Due to
the risks with the propeller behind the
pilot, the J 21 was one of the first
aircraft in the world to be fitted with
an ejection seat.

On July 30, 1943, the 21
performed its maiden flight and on
December 1, 1945, the first examples of
the J 21A-1 were introduced to service.
It was quickly followed by the improved
J- 21A-2, which featured heavier
armament, and the A-21A-3
fighter-bomber. Due to Swedish Air
Force interest in jet fighters, SAAB
would later produced a conversion using
the British de Havilland Goblin it was
designated the SAAB 21R.
IL-2 Sturmovik Type 3

unleashes a stream
of destruction from its four machine
guns and two heavy rocket
cannons
that spit
forth explosive incendiary shells.
Tanks, trucks, and

Brief
Aircraft History
Model 83, designed for the Navy, had a
hook-type arrester so that it could land
on aircraft carriers. Its production
version was designated F4B. Model 89,
built for the Army as the P-12, could
hold a 500-pound (226-kilogram) bomb.
The
military bought 586 of these fighters in
different versions. The first was
delivered to Army Air Corps Captain Ira
C. Eaker on Feb. 26, 1929, for a special
goodwill flight to Central America.
Later, Brazil became an international
customer for the fighters.
Boeing built four commercial versions of
the model; the U.S. Bureau of Air
Commerce, precursor to the Federal
Aviation Agency, bought one, and Howard
Hughes bought a two-seat version.
Hawker Hurricane Mk II
David’s

Brief Aircraft History
While the Hawker Hurricanes fame was
later eclipsed by the Supermarine
Spitfire, it played a major role in
early air conflicts, especially the
Battle of Britain. Produced from
1937 to 1944, it served throughout most
of the war and racked up some pretty
impressive facts and figures.
During the Battle of Britain in July
1940, the RAF had a total of 527
Hurricanes and 321 Spitfires to face the
Luftwaffe’s 2,700 planes. Ultimately,
the British forces were successful in
destroying 1,887 aircraft to British
losses of 1,547 planes over the
three-month period. Their success
marked a turning
point for Britain and th e war, halting
the Nazis’ advancement in Europe. While
slower and less agile than the Spitfire,
one of the Hurricane’s saving graces was
that it was known to hold up better
against enemy fire. In the Battle of
Britain, they helped provide cover for
the Spitfires, taking the brunt of the
damage as the Spitfires moved in for the
kill.
Besides the Mark II (A&B), there was the
Mark II Trop (rigged for combat in North
Africa), the Sea Hurricane (modified to
be launched by catapult for convoys),
the Hurricane Hotspur (with a turret gun
placement), the Typhoon, and many other
variants.
Of the 14,588 Hurricanes built during
its 7 year production, only 13 survive
today that can still fly.

In December
1937 the Imperial Japanese Army Air
Force issued a requirement for a
two-seat, twin engine heavy fighter. A
design team headed by Tako Doi
went to work and came up with an
aircraft not dissimilar to the
Messerschmitt Bf 110 ... the
Kawasaki Ki-15 Toryu. The
word Toryu means "Dragon Killer", which
was the purpose of this aircraft who's
specific design was intended to be a
superior night fighter for Japan's home
defense against US bombers.
David's
1/5th Scale design is an excellent flyer
with stable flight and landing
characteristics. The aircraft can
be powered by two 50cc gas motors but a
few flyers are building theirs with
equivalent electric motors.

Brief
Aircraft History
The first
Kawasaki Ki-45 Toryu (dragon
killer/slayer) prototype flew in 1939, a
cantilever mid-wing monoplane with
retractable tailwheel landing gear.
A slender fuselage provided enclosed
accommodation for two in tandem.
Problems
followed with the engine installation,
and it was not until September 1941 that
the Ki-45 KAIa entered production.
Armament of this initial series version
comprised one forward-firing 20mm
cannon, two 12.7mm machine-guns in the
nose, and a 7.92mm machine-gun on a
flexible mount in the rear cockpit;
there was also provision to carry two
drop tanks or two 250kg bombs on
under-wing racks. This type
entered service in August 1942
but was first used in combat during
October 1942, soon being allocated the
Allied codename "Nick". The
Ki-45 KAIa was joined by a new version
developed especially for the
ground-attack/anti-shipping role, the
Ki-45 KAIb. Standard armament
comprised one 20mm cannon in the nose, a
forward-firing 37mm cannon in the
fuselage, and one rear-firing 7.92mm
machine gun, plus the under-wing
provision for drop tanks or bombs; a
number of alternative weapon
installations were tried experimentally,
including the use of a 75mm cannon for
attacks on shipping.
The Ki-45
KAIa was, for its day, heavily armed and
proved quite effective against the
USAF's Consolidated B-24 Liberators and
when these bombers were used more
extensively for night operations, the
Ki-45 was adapted to attack them.
This is when the night-fighting
capability of the type was discovered,
leading to development of the Ki-45 KAIc
night-fighter that proved to be one of
the most successful Japanese aircraft in
this category. Ki-45 Toryu's
remained in service until the end of the
Pacific war, production totaling 1,701
including prototypes, being used for the
defense of Tokyo, and in the Manchuria,
Burma and Sumatra areas of operations.

Brief
Aircraft History
The
XBT-1 was designed in 1934 in response
to a navy request for a dive bomber. It
was a low wing monoplane, of all metal
construction apart from fabric covered
control surfaces. The prototype
was powered by a 700hp Pratt & Whitney
R-1535-66 Twin Wasp Jr. engine, later
replaced by an 825hp R-1535-94. Powered
by the latter engine the BT-1 was
capable of carrying a 1000lb bomb, had a
service ceiling of 22,500ft and a top
speed of 212 mph.
The US
Navy placed an order for 54 BT-1s in
1936. The aircraft entered service
during 1938, and served on the USS
Yorktown and USS Enterprise.
The aircraft was not a
success in service. Aware of the
failings of the BT-1, Northrop soon
began work on an improved XBT-2. The
new aircraft was given a more powerful
Wright XR-1820-32
Cyclone engine, providing 1,000hp,
combined with a redesigned control
system. It first flew on 25 April 1938,
but was not a significant improvement,
six months of tests followed, resulting
in a significantly better aircraft.
During this process
Northrop resigned from his company that
by now was a fully owned subsidiary of
Douglas. The new aircraft was thus
given the designation XSBD-1
(Experiment, Scout Bomber, Douglas). It
would go on to be the most successful
American dive bomber of WWII, commonly
called the "SBD Dauntless".

Thomas Morse Scout S4C
This exact 1/5th Scale
Thomas Morse Scout S4C is suitable
for R/C competition, a museum static
display or everyday enjoyment at your
R/C flying field! This aircraft
has a removable tail for easy transport
and also makes for a unique electrically
powered model that can be powered
economically.
Built by
Thomas-Morse Aircraft in Ithaca, New
York in 1917, it was a compact
single-seat open-cockpit biplane of
equal span and a 100hp Gnome rotary
engine. The S-4
made its maiden flight in June 1917 in
the hands of Paul D. Wilson. Twelve
planes went to the Navy.
Nicknamed
the “Tommy", the Thomas Morse
Scout S4C was the standard
single-seat advanced-trainer used by the
US Air Service during World War I. The
S-4 flew at practically every pursuit
flying school in the United States
during 1918 and was the first plane
built specifically for this purpose.
Most
foreign governments used obsolete or
war-weary airplanes for training, but
since the Unites States had no pursuit
aircraft of its own, it had to build
advanced-trainers from scratch.
The Bristol F.2 Fighter
was a two-seat biplane fighter and
reconnaissance aircraft and was without
a doubt one of the most important and
successful British designs to serve
during the First World War.

Brief
Aircraft History
In 1915 the Royal Flying
Corps had identified a need to replace
their Royal Aircraft Factory B.E.2c's
with an emphasis on self-defense
capabilities. Designed by a team led by
Frank Barnwell,
the prototype Bristol Type 12 F.2A
(C3303) was first flown on 9th September
1916 in Filton, England, and fitted with
the newly available 190 hp Rolls-Royce
Falcon 1 inline engine.
50
Bristol Type 12 F.2A’s were produced
before construction switched to Type 14
F.2B. This final version became the
definitive Bristol Fighter. A few of
the earlier Bristol F2B was fitted with
the Falcon I or Falcon II engines, with
the bulk of the aircraft being fitted
with the Falcon III that meant they had
a top speed of around 123mph and could
reach 10,000 ft. about 3 minutes faster.
The
F.2B featured a fully covered lower wing
center-section and downward sloped
longerons in front of the cockpit to
improve the pilot’s view when landing
and despite being a two-seater it was an
agile dog-fighter which had superiority
over many of its single-seater
opposition.
Miles M.38 Messenger 2A
David 's latest design
(September 2020) is a wonderful subject
in 1/3rd Scale ... a Miles M.38
Messenger 2A and it's
one of the more famous aircraft from
WWII used by
Field Marshal B L Montgomery "RG333"
Brief
Aircraft History
The Miles M-38 Messenger
was designed to meet a British Army
requirement for a robust, slow speed,
low maintenance air observation post and
liaison aircraft. The aircraft
designed was a cantilever low-wing
monoplane with a fixed tailwheel,
powered by the de Havilland Gipsy Major
1D inline engine. Fitted with
retractable auxiliary wing flaps
enabling a wing loading of around 12.5lb
per square foot, the
Messenger featured
triple fins and rudders in order to
maintain sufficient controllability down
to the exceptionally low stalling speed
of 25 mph.
Montgomery's Miles
M.38 Messenger was written off (damaged
beyond repair) 22/8/1945: Forced landing
at Oldenburg, Lower Saxony, Germany
after engine failure. Passengers
on the airplane were Field Marshal
Montgomery and his Aide-de-Camp Capt.
Noel Chavasse. The pilot was
Flight Lieutenant T. Martin. Chavasse
and Martin were uninjured in the
accident but Montgomery suffered two
cracked vertebrae. Note that the
aircraft that currently (2020) flies as
"RG333" is not the original aircraft
that was written off as previously
described but a different Messenger,
which is painted to resemble RG333.
Montgomery
standing in front of his Messenger (on
LF), his Flying Officer, Martin stands

Our good
friends at the "Large Model Association"
in England had a fly-in during 2017
where, Phil Clark, flew his
scratch-built 1/3.5-scale model of the
British liaison aircraft is powered by a
Zenoah 62cc gas engine.
The
124-inch-span plane weighs 36 pounds and
sports Royal Air Force colors. The
original plane was outfitted with
retractable auxiliary wing flaps and
triple fins and rudders to maintain
controll-ability down to an
exceptionally low stall speed of just
25mph. And big Thanks

code-named Babs by the Allies, was the
fastest production aircraft in the
world! The Ki-15 Karigane (Wild Goose)
is a two-seat reconnaissance aircraft
with a top speed of 300 mph.
Construction began in December 1935 and
the prototypes exceeded all
expectations. About the same size as a
P-47 Thunderbolt but only one-third as

The Lavochkin
La-7 was a Soviet fighter aircraft of World War
II. It was a refined development of the
Lavochkin La-5 and the last in a family of
aircraft that had begun with the LaGG-1 in 1938.
Considered the last "Grand Piano", it was
evolutionary rather than revolutionary. The two
highest-scoring Soviet aces flew the La-7, one
of them; Ivan Kozhedub was the top Allied ace of
the war.
The
Grumman light aircraft line was acquired by
Gulfstream Aerospace in 1977 which formed their
light aircraft division, Gulfstream American.
After completing a major redesign of the AA-1B
the new AA-1C was born. Two versions were marketed,
differentiated by avionics and the external
trim. The Lynx was targeted at private owners
while the T-Cat was the flying school trainer.
Arado Ar 96B was a German single-engine, low-wing
monoplane of all-metal construction produced by Arado Flugzeugwerke. It was the Luftwaffe's
standard advanced trainer during the Second
World War. For of you unfamiliar with this
aircraft, the Germans use it much like we used
our AT6/Harvard's. This is an extraordinary
