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. ...

Epoxy Glue

Epoxy : A two-part resin/hardener glue that is extremely strong. It is generally available in 6 and 30-minute formulas. Used for critical points in the aircraft where high strength is necessary. Wikipedia Epoxy: Epoxy is both the basic component and the cured end product of epoxy resins, as well as a colloquial name for the epoxide functional...

Endpoint Adjustment

Endpoint Adjustment : This radio feature adjusts the length of servo travel in one direction (a single channel will have adjustments for two endpoints). If your plane rolls faster one way than the other, endpoint adjustments can correct the problem. ...

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...

Four Stroke (Four Cycle)

Four Stroke (Four Cycle): Although a 4-stroke engine has less power than a 2-stroke engine of comparable size, there are advantages to 4-stroke engines. They do not require a muffler and are often quieter than most 2- strokes are with a muffler. They can swing a bigger prop than the same size 2- stroke engine. This is an asset in the large, slow-flying aerobatic and scale models where 4- stroke engines are usually mounted. Lastly, the fuel economy is bett...

Flight Pack - Airborne Pack

Flight Pack or Airborne Pack : All of the radio equipment installed in the airplane, i.e., Receiver, Servos, Battery, Switch Harness. This is not a similar thing to the flight box, rather it refers to all the radio equipment that is used in an RC aircraft during flight. This includes most importantly the receiver, but also the servos/ESC, flight...

FHSS - (Frequency Hopping Spread Spectrum)

FHSS (Frequency Hopping Spread Spectrum) :   — A 2.4GHz radio system which switches from one "free" frequency to another every few milliseconds. While jumping from one to the other frequency, you are not spending much time on that frequency and this keeps out interference. See also: DSSS. Wikipedia: Frequency-hopping spread spectrum (FHSS)...

DSSS (Direct Sequence Spread Spectrum)

A 2.4GHz radio system which selects one (or two) of the available "free" frequencies and transmits only on the one(s) chosen. Like FHSS (Frequency Hopping Spread Spectrum) systems, it is resistant to electrical noise. See also: FHSS. Wikipedia: In telecommunications, direct-sequence spread spectrum (DSSS) is a modulation technique. As with...
