This is really challenging. You must start from any airport, keep the cargo with the hook under the Helicopter and bring it to another airport. Detach it with AG 2, safely on the ground, then land.

The control system I have chosen is an evolution of what I have studied for my previous helicopter, the SNAW HGA 01 (https://www.simpleplanes.com/a/Bca0Or/SNAW-HGA-01)

VTOL = Collective pitch of the rotors
Upward: positive pitch to fly, Downward: negative steps, useful to get off quickly from relatively high altitudes

TRIM = Angle of attack of the Rotors
Upward they lean forward and move forward, reverse the other way

THRUST = Engines rotation speed

These three commands require to be used with a certain balance. Maintaining a stable quota is obtained mainly by varying the collective pitch, bearing in mind that an excessive step with low engines rotation speed causes a fall in the speed of the blades, and therefore of the thrust. Giving angle to attack the rotors causes a component forward, and the loss of the same component vertically, if you do not compensate with the gas or with the collective pitch you will start to descend.

As the altitude or the situation changes, the equilibrium can be achieved with engine revolutions slightly different from test to test, considering a variation of plus or minus 2% as a normal adjustment.

AG1 = lights
AG2 = detach hook

The other three axles are absolutely standard.

For a perfect takeoff from wright airport:

THRUST 27% (26-30%) - Climb the TRIM slowly up to 50% - at first notch (The helicopter takes off gently and begins to rise vertically) - VTOL 50% up - at first notch (the rotors incline in ahead and the whole helicopter follows them.You lose vertical thrust and you acquire horizontal speed, until you stabilize.To stabilize the altitude may need adjustments between THRUST and VTOL, but this is normal in the absence of an autopilot).

The Helicopter can land and take of from water too.
