My Requirements ...
Well you must start somewhere, and before you can select an aircraft, you must know what your requirements for flight are.
Do you just need a day tripper or a cruiser, how fast, what touring radius, required payload, galley with coffee machine,
(I'm sure you have the picture now), and the list goes on and is long.
So with the desires, goals, thresholds and shatterd dreams all sorted out, this is what became my requirements:

About the Cherry BX-2 ...
|
The Cherry BX-2 is a light-weight, two seat side-by-side aircraft of composite construction. The aircraft is constructed
from a variety of materials, the major materials (in no particular order), being Wood, Plywood, Fibreglass and epoxy resin,
Aluminium, ChromeMoly Steel, Stainless Steel, Phenolic resin, Plexiglass, and Styrodur Foam. Construction is from plans
with no kit being available, all construction is expected from using your own manufacturing facilities. Welding and Painting
are expected to be contracted to experts in their field to ensure good workmanship. Expected construction time is 3000 hours.

This low-wing monoplane has quick detachable wings and retractable undercarriage. Flap movement is transferred to the
ailerons in a reduced rate.
The aircraft has a pendulum-elevator with anti-servo-flap trim. The nose-wheel is steerable and incorporates a rubber-block
shock-absorber. The main-wheels have a hydraulic braking system which is applied simultaneously from a brake lever. The
canopy offers excellent vision in all directions and slides forward for opening. While the rudder is cable controlled,
the elevator and aileron movement is transmitted by rod control.

The United States of America, FAR 23, which also applies in Switzerland, was used for load assumptions, speed rating and equipment.
This aircraft is designated for the "Experimental" category. A good aerodynamic has been chosen for the aircraft to preserve performance.
Good economy and low noise emission are also features of the aircraft. Dimensions have been kept compact rather than having to
increase wing aspect ratio.
|
|
Permanent hangerage for the aircraft is not a requirement. The horizontal stabilizer is removable and can be stowed in
the cockpit and by pulling a bolt, the 30kg wings can be removed. The Cherry and wings can then be loaded onto
a simple trailer for transporting and off-field storage. Dis-assembly and loading would take about 15 minutes.
