Multipurpose heavy coaxial rotor compound helicopter.
Based on the real life Sikorksy-Boeing SB-1
Spacious and powerful enough to seat up to 16 kerbals or carry several tons of cargo.
UPDATE 1/5/2023: Fuselage has been simplified by using fairings, rotor blades have been adjusted to handle higher speeds and controls have been adjusted. New Maximum Speed is 160 m/s at sea level and 180m/s at 4000m. For maximum speed, gradually increase pusher propeller angle to just below 40 degrees, and reduce main rotor deploy angle to less than 1 degree.
Instructions for flight:
Press AG 1 to toggle fuel cells.
Control main rotor lift and control authority with translate up/down (I/K)
Control Pusher propeller pitch with translate Forward/Back (H/N)
Control main rotor and pusher propeller torque with main throttle.
Control main rotor brakes with AG 2 and brakes for the pusher propeller with AG 3.
Action Group 4 Toggles rear elevator deploy.
Action Group 5 Toggles lower rotor roll control (useful at high speed)
Action Group 6 Toggle doors open/close
Action Group 7 Toggles doors lock/unlock.
Control landing leg locks with AG 0 (lock prior to landing).
At maximum torque, lift will occur at approximately one degree.
Flying with main rotor only, top speed is approximately 40 m/s. Do not exceed main rotor deploy angle of 5 degrees.
When using the pusher propeller, reduce main rotor control to less than one degree at speeds above 50 m/s. Cruise speed is achieved with 22 degree deploy angle. Maximum speed is approximately 130 m/s.
