HISTORY
The Antonov An-2 (nicknamed "Annushka" or "Annie" and NATO reporting name “Colt”) is a
single-engine biplane utility and agricultural aircraft that was designed in the USSR in 1946. The
AN-2 saw use as a light utility transport, a parachute drop aircraft, an agricultural work aircraft
and many other tasks suited to such a large slow-flying biplane. Its slow flight ability made it
suited for short, unimproved fields. Some variants were built for cold weather and other extreme
environments. The Guinness Book of World Records states that the 45-year production run for
the AN-2 was for a time the longest ever, for any aircraft – exceeded only recently by the
Lockheed C-130 Hercules.
By 1960 the USSR had produced over 5,000 of this aircraft. Since 1960, most AN-2s have been
built at Poland's WSK factory in the city of Mielec in south-eastern Poland, with over 13,000
made there before full production ended in 1991. Limited production from parts stocks, as well
as spares and maintenance coverage continued until 2001, when four were produced for
Vietnam. China also builds the AN-2 under license as the Shijiazhuang Y-5.
This RC version we designed is approximately 14% scale, with a 102” wingspan and is
designed for the customer’s choice of gas/glow or electric power systems. There are two
different color schemes available, Red or Blue at your choice.
IMPORTANT SAFETY PRECAUTIONS

it. Any testing or flying of this model airplane is done entirely at your own risk.
2. Assemble the model airplane according to these instructions. We recommend that you do
not alter or modify the model, as doing so may result in an unsafe or unworkable model. In a
few cases the instructions may differ slightly from the photos; in those instances the written
instructions should be considered as correct. If you have any question or concern about
these instructions, before you proceed with assembly of this product, contact us at (562)

8. While this kit has been flight-tested to meet or exceed our rigid performance and reliability
standards in normal use, if you plan to perform any extremely high-stress flying, such as
racing or advanced aerobatics, or if you plan to install a larger engine (or motor) than
specified, you (the buyer or user of this product) are solely responsible for taking any and all
necessary steps to reinforce the high-stress points and/or substitute hardware that is more
suitable for such increased stresses.
9. This model may include fiberglass and/or carbon-fiber reinforced plastic parts that may
require some cutting or sanding. Carbon-fiber and fiberglass dust may cause eye, skin and
respiratory tract irritation. If you ever grind, drill or sand such parts, always wear safety
goggles, a particle mask and rubber gloves; never blow into such a part to remove fiberglass
or carbon-fiber dust, as the dust may blow back into your eyes.
