Light-weight-aircraft, 2 seats (side by side),
composite-construction (lumber, Styrofoam, glass-fibre and epoxy).
Low-wing monoplane with quick removable Wings and retractable
nose-wheel-landing-gear. The Flap movement is transferred to the
aileron in a reduced rate. Pendulum-elevator with anti-servo-flap.
Nose-wheel-steering and a shock-absorber (rubber) for the
nose-landing-gear. Main-landing-gear made of strands on a
lumber-core, hydraulic-brakes simultaneously applied by lever.
Full-sight-canopy slides opens in fwd direction. Rudder is
cable-controlled, elevator- and aileron-transmission is rod
controlled.
Constructional guideline
The load-assumptions, speed-rating as well as equipment were taken
from the American
FAR 23 which is also valid in Switzerland.
Nevertheless the aircraft remains an ”Experimental”.
A Good aerodynamic was chosen to save Performance. Economy and low
noise emission go along with that. Dimensions were kept compact
rather than increasing wing aspect ratio for even better
aerodynamics.
The construction was based on own manufacturing-facilities (welding
and
painting outside).
Hangar/transportation
Permanent hangar-space is not necessary for the aircraft.
For transportation both stabilizer-halves are removable and can be
stowed in the Cockpit.
Then the ”Cherry” will be towed on a simple trailer and fixed. By
pulling a bolt the Wings (30 Kg) can be removed and fixed on the
trailer beside the fuselage.
Homebuilders requirements
The aircraft is not built in a primitive manner and requires
anywhere from good up to advanced craftsmanship. The project
requires about 4000 hours. Even if the prototype swallowed just 10
000 SFr till it’s 1st flight (including engine and instruments) it
is recommended to assign at least 20 000 SFr.
During the construction period, which takes a few years, you can
easily do without travelling or other expensive activities and thus
save quiet the amount of money needed for this project.
