K-MAX Full-Size Remote-Controlled Helicopter Video
Kaman Aerospace has teamed with Lockheed Martin
to create a full-size, radio-controlled version of their K-MAX helicopter. It is
already in use with the military. Kaman is famous for its twin rotor "synchropters."
Per the Kaman website: "The simplicity of design of the K-MAX® presents a machine
that is inherently safer and more reliable. A single engine, a single transmission,
a servo-flap controlled, counter-rotating rotor with no high-pressure hydraulic
system, and no tail rotor all present a simple, straightforward design with fewer
essential systems. The highlight of this simple design is the counter-rotating rotor
system, where all the torque is reacted within the transmission. Unlike tail rotor
machines that constantly stress the airframe between the rotor and tail rotor, the
K-MAX® contains all that, and more power, in the transmission."
