Flutter (Aircraft Flutter)

Flutter: A phenomenon whereby the elevator or aileron control surface begins to oscillate violently in flight. This can sometimes cause the surface to break away from the aircraft and cause a crash. There are many reasons for this, but the most common are excessive hinge gap or excessive "slop" in the pushrod connections and control horns. If you ever...

Flaps

Hinged control surface located at the trailing edge of the wing inboard of the ailerons. The flaps are lowered to produce more aerodynamic lift from the wing, allowing a slower takeoff and landing speed. Flaps are often found on scale models, but usually not on basic trainers. ...

Elevator

Elevator: Hinged control surface located at the trailing edge of the horizontal stabilizer, which provides control of the airplane about the pitch axis and causes the airplane to climb or dive. The correct direction of control is to pull the transmitter elevator control stick back, toward the bottom of the transmitter, to move the elevator upward,...

ESC - Electronic Speed Control

Electronic Speed Control (ESC): Electronic speed controls replace the mechanical speed control and servo providing enhanced power efficiency and precision in an electric R/C car, airplane, helicopter or boat. In addition, they are lighter which improves the performance of some electric models. Wikipedia: An electronic speed control or ESC is...
