GLOSSARY
It will be helpful to understand the following terms before reading the rest of the manual. The terms are not in alphabetical
order, but are in a logical order that prepares the reader for understanding the next term.
Reversing (servo reversing) – A function that allows the user to determine the direction of response of each servo. If, after
hooking up the servos, a control on the model responds in the wrong direction, the user may change the servo s direction so
the control responds correctly.
Throw – When speaking of a control surface (such as an elevator or aileron), the throw is the
distance the surface moves. Control surface throw is usually measured at the trailing edge of the
surface and is expressed in inches or millimeters. The model in the diagram has 1/2" [13mm]
of up elevator throw. Throw can also refer to the distance a servo arm (or wheel) travels.
Dual rate (D/R) – On the 6EXA the dual rate switch allows you to instantly switch, in flight,
between two different control throws for the aileron and elevator. Often, different control
throws are required for different types of flying. (“Low” throws may be required for flying at
high speeds where the model’s response becomes more sensitive, and “high” throws may be required for aggressive aerobatic
maneuvers or landing or flying at lower speeds where the model s response becomes less sensitive.)
End point adjustment (E.P.A.) – Sets the overall, maximum distance the servo rotates in either direction. (No matter where
the dual rates are set, the servo will never travel beyond the limit set by the end point adjustment.)
Exponential – Normally, servos respond proportionally to control stick input from the transmitter (e.g., if the stick is moved halfway,
the servo will move halfway). However, with “exponential,” the servo can be made to move more or less than initial stick movement
(less servo movement is more common). Exponentials are commonly used to “soften,” or decrease initial servo travel for the ailerons
and elevators. This way, initial control stick inputs from the pilot result in small servo movement for a smoother flying airplane. (Dual
rates adjust the amount of servo travel. Exponentials determine where most of the travel will occur.)
Mixing – Two (or more) servos can be made to operate together either by mechanically joining the wires (with a Y-connector)
or by electronically “joining” them through programming functions in the transmitter. When servos are electronically joined
via programming, they are said to be “mixed.” Unlike joining servos with a Y-connector, when servos are mixed electronically
they can be made to move in opposition. Additionally, each servo’s end points can be independently set.
