How to recognize the R44

The R44 is small, light and bubble-shaped, with a thin tail boom and a rotor on a tall mast.

  • Rotor: a two-bladed main rotor on a tall mast, giving a distinctive wop-wop sound.
  • Engine: a piston engine mounted low behind the cabin, partly visible through cooling openings.
  • Landing gear: skids.
  • Cabin: a bubble-like front with two rows of seats and four doors.
  • Tail: a long, thin tail boom with a small horizontal stabilizer, upper and lower fins, and a two-bladed tail rotor.
  • Size: noticeably smaller than turbine helicopters like the H125.
  • Sound: a light, rhythmic thumping, less of a whine than turbine helicopters.

The two-seat R22 looks similar but is smaller, and the five-seat R66 has a turbine engine and a slightly bigger cabin. The H125 is larger, with a three-blade rotor and a turbine engine.

The R44's rotor mast is tall and thin, with the two-blade rotor and its teetering hub sitting well above the cabin. The cabin has a large, rounded windshield and side windows that wrap around the front. Police and news versions often carry a camera ball under the nose, while float-equipped Clippers have large pontoons attached to the skids. The skids themselves are long and slim, and the helicopter looks light and delicate next to turbine models.

Where and when you'll see it

Flight schools, tour operators, news stations, police departments, aerial photographers, ranchers and private owners fly R44s across the US. They are common near cities for news and police work, in agricultural areas for crop and livestock work, and at tourist spots for scenic rides.

Most flights are 500 to 1,500 ft above ground. On ADS-B the type code is R44, with the rotorcraft emitter category; callsigns are usually the N-number. Training helicopters often hover and practice autorotations near airports. See why helicopters circle.

Because they are relatively inexpensive, R44s are often used for short sightseeing rides at tourist areas and for aerial photography over real estate and construction sites. In farm country, ranchers use them to check cattle and fences, and crop surveyors fly them low over fields. Training helicopters fly many short patterns around airports during the day.
