Update: main rotor power slightly increased, added signal lights will blink when fuel cells are active, probe core removed

This craft uses no RCS or mods to fly, and is stable enough to be flown with just a keyboard without SAS engaged.

A simplified replica of the Bell 47 Helicopter. This model was the first approved for civilian use, adopted by all US Armed Services and was heavily featured as an air ambulance in the 1970-80s TV show ‘M*A*S*H.“

AG1: activates the fuel cells.

Keys:

I/K: Controls Main rotor pitch. This craft will take off will as little as +2-3 degrees of pitch. Make sure the rotor deploy is set to extended and pin the control menu so you can monitor main rotor pitch.

A/D: Controls tail rotor torque via adjusting the target angle of the rotatron at the base of each tail rotor blade. Controls just like normal yaw, but will maintain the angle settings. Pin the rotatron menu so you can monitor tail rotor angle. If you find your helicopter spinning in one direction, adjust tail rotor in the opposite direction.

Pitch and Roll control as normal.

Both rotors are slaved to the main throttle.

Because KSP doesn’t like helicopter physics, the aircraft will sometimes vibrate slightly, cycle the main rotor autostrut to none.
