The Antonov An-2 is currently the world’s largest single engine biplane. It has short take-off and landing (STOL) capabilities, using ailerons which can be lowered 20 degrees in conjunction with its flaps. The aircraft are used for smoke jumping, paratroop transport, glider tug, utility transport, water bombing, and training.
Antonov An-2 production started in 1947. We are told that it is still being produced by the Chinese State Asset Management Commission and Polskie Zaklady Lotnicze (Polish Aviation Works). The aircraft is in the Guinness Book of World Records for having the longest production run of any aircraft in history.
The Antonov An-2 has easy to remove, dual slide-tray mounted heavy duty batteries with attached connectors. Pneumatic connectors located in the bottom of the fuselage allowing the attachment of hoses to the aircraft’s air brake compressor line. Easily removable main tires with automotive type beads ease service. Fuel system access fitting in the bottom of the fuselage allowing use of aircraft power for loading. There is a 32 gallon engine oil reservoir. The engine is said to operate on a minimum of 6 gallons.
Pilots report flying the Antonov An-2 as a docilely mannered, yet unpleasant aircraft to fly.
During taxi, the pneumatic brakes of the Antonov An-2 are controlled from the yoke of the aircraft. More than a light application may have the aircraft standing on its nose.
At a fifteen degree flap setting, the Antonov An-2 will do a 3-point take off after a run of a little over 1,000 feet. Climb out is at about 700 feet per minute.
Although the Antonov An-2 has electric trim, there are no position indicators. A light system only tells you that the trim tab is in the neutral position.
The controls of the Antonov An-2 are extremely heavy and very slow to respond.
Fuel consumption at cruise for the Antonov An-2 is around 45 g. p. h.
The Antonov An-2 is definitely built for controlled slow speed flight. It flies the same down to about 35 mph as it does at its cruise speed.
Cross wind landings in the Antonov An-2 can be challenging due to semi slab sides and large vertical stabilizer. Pilots report that the aircraft will bounce a bit on anything but a perfect landing.
A total of over 18,500 Antonov An-2 aircraft of all types have been produced to date.
RC Antonov An-2
The RC Antonov An-2 plans by Flying Scale Models build to a wingspan of 50.5 in. Recommended power is with .19 to .25 two cycle engines.
Check out RC Groups for meatbomber and his really nice looking card model RC Antonov An-2. He plans to use it as the basis for a 49 in. wingspan RC An-2 that he is building.
