The propellers act as a thrusting force which drives the airplane forward. In addition to the wings and vertical and horizontal tail wings, this helps an airplane to become airborne and fly.

The three basic control surfaces of an airplane are the ailerons, rudder and elevators. Ailerons are on the trailing edges toward the outboard end of the wings, and can roll an aircraft. The rudder, which is in the vertical part of the tail, can cause the tail to be "forced sideways" and affect the yaw. Lastly, the elevators are in the horizontal parts of the tail, and they can cause the tail to be "forced up or down" and this will control the pitch.

The fuselage is the part of the airplane that contains the cabin and has the wings, tail and engines bolted to it. The fuselage carries the plane's load, and it's why people buy airplanes in the first place.
The tail propeller keeps the helicopter straight.
It part of the tail.
Tail will tilt up
"tri"means three so a tri-motor airplane has three engines. the most common tri-motor airplane will have one engine on each front wing and one engine on the tail or back wing. many tri-motor airplanes are considered jets. "Trimotor" refers to one airplane in particular--it's made by Ford. This plane has three radial engines driving propellers. The plane's fuselage is made of corrugated metal, kind of like that you'd find on a shed roof, for extra strength. The Ford Trimotor was about as sophisticated as an anvil and nearly as reliable--some of the Trimotors, all of which were made before World War II, are still flying.
They change the speed and angle of rotor, and speed of tail propeller.
