The
Focke Achgelis 330 is considered the first helicopter for observation, the strange
aspect of this model is that IT DID NOT HAVE AN ENGINE and rose by means of the action of the winds in the sea.
Since
there is no availability of this type of model in Colombia, I built it
with pieces of sprue, a chair that exceeded of a kit and a remaining pilot
of another kit.

The
Fa 330 Bachstelze was a marvel of the design, simple and effective, all
his structure weighed scarcely 81 kilograms and consisted of a lone pipe of steel to which all the parts were welded. The diameter of
the disc of the rotor was 7,31 m. Supporting a load of 365 kg, including
the pilot.
It
relied on a exposed seat where there was a seated pilot and
a tail unit that was included a stabilizer, a drift and a helm of
direction. In front of the pilot was a panel of instruments that
included a compass, tacometer electrically and a telephone to communicate
with the submarine that was towing this aircraft.
All
this structure was resting on a few skids that allowed the helicopter to land on the submarine.
Nevertheless one of the most peculiar features
they were the blades
of the rotor that had an ingenious device that allowed thenm to incline to alter his angle of effect.
The
flight of the Bachstelze happened when the submarine was sailing in the
surface, the rotor was first spun by hand by the pilot to acquire the initial
rotation, which then was continued by air flow produced by the moving
submarine. Next the device would rise
as if it was a kite hanging at the end of a cable that was
anchored to the submarine and was kept airborne by the movement of the
ship.
Upon
completion of the observation mission, the helicopter was lowered by means
of a wheel and dismantled for storage. Inside the bucket of the rotor,
there was a brake in the center to immobilize the blades when it (he) was gathered
and guarded.
On
the other hand the Bachstelze relied on a device for emergency descent if the
submarine needed to submerge quickly. The pilot of the helicopter had a lever
to release the rotor from the frame of the aircraft. A parachute was located in the
rear part of the mast and was
activated automatically as the pilot gave up the safety belt and the whole
fuselage was fell to the sea.
The
pieces of sprue were cut away carefully bearing in mind the measurements of a
photography diminished to scale 1:72, later assembled the whole set and it made
up since like it appears in another image of the real device
