Simple heavy cargo helicopter. Uses the a rotator engine.

Throttle up to get the blades spinning. Literally 1% is enough and will not make any difference between 1 and 100%.
VTOL to control the blades' angle of attack. Hover position would be around 1/3 up.

Group 1 is for setting the parking break.
Group 2 is for nav lights.
Group 3 is for landing lights.

IMPORTANT.
The craft will slowly spin either left or right and depending on the blades' angle you will have to do little or alot of correction. Also, since it is a rotator engine, at one point it will stop spinning. Also, if you apply breaks aka zero throttle, the blades will start spinning the opposite direction. You can still remain the in the air by reversing the angle of attack.
