Testimonial from Beatrice Koch, Switzerland: "My training at Mauna Loa Helicopter Flight Schools was an awesome experience!  I came here from Switzerland without any knowledge about flying at all, and I wasn't really sure if I would be able to make it.  But now I got my private pilot's license, I still can't believe it."

Learn About Our Helicopters

Mauna Loa Helicopters flies Robinson helicopters, the most popular rotorcraft in the world. The four seat model R44 is the most popular helicoptor in production today, and the two seat model R22 has the lowest acquisition and operating costs of any production helicoptor. Wherever you fly in the world, chances are that you will spend some time in a rotorcraft built by Robinson Helicopter Company.


Robinson R-22

Excellent performance, great reliability, and robust construction make the two-seat R-22 ideal for flight training.  More than 3,600 R-22 helicopters have been delivered to more than 60 countries.  The R-22 holds major performance records in its weight class including speed and distance.  Mauna Loa Helicopters flies the Beta II version of this aircraft exclusively.

The Beta II's clean aerodynamic design allows a top speed of over 100mph and a miserly fuel burn of about nine gallons per hour. The cabin provides comfortable seating for two with removable dual controls on the passenger side.

No other helicopter in its class can match its speed, reliability and low operating costs.  Robinson Helicopter's commitment to high quality in design, materials and craftsmanship make the    R-22 an obvious choice for flight training and other applications that require performance, dependability, efficiency and easy maintenance.

Robinson R-44

Mauna Loa Helicopters uses the Robinson R-44 Raven II exclusively, a terrific aircraft equipped with a fuel-injected, angle-valve, tuned-induction, IO-540 Lycoming engine which produces good power, speed, altitude performance and useful load.  The Raven II is also quieter than its predecessor, the Raven I.

The engine is de-rated to 245 HP for 5 minutes and 205 HP maximum continuous rating to assure a longer life and lower cost of maintenance. Main rotor blades have greater effective lifting area which reduces vibration.

Main and tail blades have new aerodynamic tip caps which reduce the 500-foot flyover noise level despite the higher gross weight.  A standard 28-volt electrical system ensures good starting performance and provides additional electrical power for optional equipment.
