Auto Credit Based on Saritone's XH-C1E

**This is the Block II iteration of my original XH-C1E helicopter. I've improved the fuel range and have tweaked the pitch angles of the blades and trim system to allow for smoother flight. I have also eliminated the uncontrolled roll when applying full collective pitch to the blades.**

START-UP: Bring the throttle to 100% and activate the number one activator to engage the engine and spool up the rotor system. After maximum rotor RPM is achieved, raise the collective (VTOL slider DOWN) and slowly bring the helicopter off the ground. Give it forward pitch to gain airspeed.

NOTE: You will notice is that the tail elevator wings rotate as you increase collective. This helps trim the A/C out in cruise flight and allows the pilot to decrease the use of RCN's.

FEATURES:
- This helicopter boasts a coaxial blade head with high inertia for rotor RPM maintainability during engine out scenarios. The blades are the only airfoil surface giving this helicopter lift. The VTOL nozzles are mounted on the rotators of the blades and thus will not give the any lift as the pitch is changed. They only serve to maintain rotor RPM.

-Unlike my previous designs where yaw input was needed to coordinate turns, this design has a proper tail that will weather vane into the relative wind and help alleviate some of the yaw input for making coordinated turns.

-The fuel range has been greatly improved without having to fill the rotor blades with fuel and thus decreasing performance.

-Fuel consumption has been cut down greatly through the use of control surfaces on the airfoils as well as a pitch trim system tied to the collective. This decreases control input for pitch at speeds above 70MPH and will allow the pilot to shut down RCN's above 75MPH and allow the control surfaces to maintain attitude control.

-Retractable landing gear for streamline performance.

-Auto rotation capabilities above 300FT AGL and above 40MPH. 0/0 landings and run-on landing are possible with no damage to air frame.

CHARACTERISTICS:
-Cruise Speed: 70-80MPH
-Climb Speed: 35-45MPH
-Climb Rate: 300-500FPS
-Fuel Range: I don't have a confirmed number, but I have been able to take off from the south landing strip and land on either the carrier or the island runway with plenty of fuel left over. I have not tried to circumnavigate the island, though. Give it a shot and see how far you can get.

CAUTION:
- If you run the tanks empty on this heli you will lose aircraft control below 75MPH due to it's use of RCN's. Be mindful of your fuel reserves.
