Wing ribs of a de Havilland DH.60 Moth. In an aircraft, ribs are forming elements of the airframe structure of a wing, especially in traditional construction.. By analogy with the anatomical definition of "rib", the ribs attach to the main spar, and by being repeated at frequent intervals, form a skeletal shape for the wing.
A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is radio controlled by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on ...
Good trainer planes and gliders can be made from SPADs. SPAD modelers make equally good advanced planes that can be made with corrugated plastic. They include: RC Airplane Combat, 3D Flying, and are preferred in places where the flyers would normally not risk a more expensive plane and yet want the same flying characteristics of balsa planes.
The Junkers all-metal corrugated-covered wing / multiple tubular wing spar design format was emulated after World War I by American aviation designer William Stout for his 1920s-era Ford Trimotor airliner series, and by Russian aerospace designer Andrei Tupolev for such aircraft as his Tupolev ANT-2 of 1922, upwards in size to the then-gigantic ...
Static model aircraft cannot fly, and are used for display, education and are used in wind tunnels to collect data for the design of full scale aircraft. They may be built using any suitable material, which often includes plastic, wood, metal, paper and fiberglass and may be built to a specific scale, so that the size of the original may be ...
Hand-launching an UMX Radian. Hand launching is the simplest way to get a model glider into the air. Depending on craft design and the conditions at launch—the pilot or an assistant need only to gently 'throw' it into the wind, at an angle deemed best suited, usually between horizontal and 45 degrees of zenith.
Hover You pull the aircraft into a completely vertical attitude and allow the propeller to hold the aeroplane in the air in plane much like a helicopter. This is the most basic 3D manoeuvre and usually the first one new modelers want to learn Torque Roll The plane is made to hover in place, rotating around its roll axis. This is an extension of ...
The aircraft was also demonstrated to the U.S. Navy and Army Air Corps. Both services were impressed with the design and on February 19, 1945 the Navy granted Republic Aviation the rights to use the name Seabee for the civilian version. The Army placed a large order for the aircraft, to be used for air-sea rescue operations under the ...
