A-10 Thunderbolt II "Warthog"
A-10 Thunderbolt II is a single-seat, straight-wing twin jet engine aircraft
developed by Fairchild-Republic for the USAF to provide air support of ground
forces by attacking tanks, armoured vehicles, and other ground targets, also
opportunistic behind lines ground attack.
It is the first U.S. Air Force aircraft designed exclusively for close air
support, intended to have long loiter time at the battlefield, low-speed
agility, massive cannon firepower, and extreme survivability; an aircraft
combining the best elements of the tankbusters Ilyushin Il-2, Henschel Hs 129 and A-1
In WWII the German Stuka Ace
Hans-Ulrich Rudel flew the Ju 87G Stuka, with 2 underwing 37 mm guns. He
destroyed 519 tanks, 70 assault craft/landing boats, 150 self-propelled guns, 4
trains, and 800 other vehicles; 9 planes, a battleship, 2 cruisers and a
destroyer. His spectacular record influenced the decision to make the 30 mm
Avanger Gatling gun the main anti-tank weapon of the A-10. It fires large
depleted uranium armour-piercing shells, at 3,900 rounds per minute
official name comes from the P-47 Thunderbolt, which was
effective at close air support in WWII. However, the A-10 is
universally known by its nickname "Warthog".
The cockpit and parts of the flight-control system are protected
by 900 pounds of titanium armour, referred to as a titanium
"bathtub". The tub has been tested to withstand strikes from
23 mm cannon fire and some strikes from 57 mm rounds.
first the Air Force command preferred the AH-64 Apache Attack
helicopter due to it's ability to loiter. But the 1991 Gulf War
proved that the A-10 can get to and from the battlefield faster,
delivering enormous firepower while there, and is more damage
resistant. Having served it's expected lifespan with no signs of
obsolesence, the A-10's are still unsurpassed in these roles.
Heavily used in Afghanistan, they are now expected to continue
produced by Aeronaut in Germany
is designed to take either
brushless propellers, or brushless ducted fans using the optional jet nascelles
kit. The builder can make it simple, or make it more complex, as preferred.
Control is via elevator, rudder
(optional), ailerons and throttle. The
ailerons are operated by two micro servos in the wings, so differential aileron
can be programmed into a computer radio to make turns more accurate.
The twin EDF version used twin 600
size (brushless) motors and needs a larger battery which makes this version
heavier and more complex. This one flies faster.
The twin 480 prop version has better acceleration from a standing start, and
it's smaller battery weighs less, so this version is less demanding of pilot
skills. The 480 motors drive two 6 x 5 or 6.5 x 4 props, and it flies really
well with this setup.
The fuselage is
pre-made epoxy fibreglass and only requires a few wood frames glued inside to stiffen it
for use. For the cockpit there is moulded clear canopy.
The wings and tail are
supplied as pre-cut balsa ribs for conventional building on a board.
Nascelles for the twin prop version are included.
The twin EDF version can be made lighter by omitting the supplied undercarraige,
and launching by a bungee catapult for belly landings. This means that no rudder
(for taxi-ing on runway) is necessary, and even more weight is saved. This gives
the EDF version a very high performance.
Access to the battery tray, and internal radio controls is by the
removable clear cockpit canopy.
