R66 Turbine
The five-seat R66 Turbine helicopter is reliable, economical and easy to maintain. R66s have a two-bladed rotor system,
T-bar cyclic and the latest in Robinson technology including streamlined instrument panels, energy absorbing seats and crashworthy bladder fuel tanks. What distinguishes the R66 is a spacious 300 lb capacity baggage compartment and the Rolls Royce RR300 turboshaft engine. The RR300 engine operates on readily available Jet A fuel and offers increased reserve power, additional payload and improved altitude performance. Hydraulic controls eliminate feedback forces and provide responsive handling.
Outfitted with pop-out floats, the R66 Turbine Marine offers an additional level of safety for over-water travel. Designed for emergencies, the six-chamber floats inflate within 2-3 seconds of activation. The installation adds approximately 65 pounds to the helicopter’s empty weight. When not in use, floats roll-up and stow in protective covers along the aircraft’s landing skids. The streamlined, low profile design minimizes drag and allows for easy entry and exit of the cabin.
With continued focus on safety, the R66 meets the latest FAA crashworthiness regulations.

R44 Raven II
Four-seat Robinson R44 Raven II helicopters are high performing, reliable and easy to maintain. R44s have a two-bladed rotor system, T-bar cyclic and the latest in Robinson technology including streamlined instrument panels and crashworthy bladder fuel tanks.
The R44’s aerodynamic fuselage optimizes airspeed and fuel economy. Hydraulic controls eliminate feedback forces and provide responsive handling. A low tail-rotor tip speed, newly designed muffler and large cambered tail reduce flyover noise.
Raven II helicopters are powered by Lycoming’s IO-540 fuel injected engine. The IO-540 delivers better altitude performance, increased payload and eliminates the need for carburetor heat.
