GLOSSARY
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) -
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 -
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.
End point adjustment (E.P.A.) -
End point adjustment (E.P.A.) -
Sets the overall, maximum distance the servo rotates in
either direction.
Exponential -
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, elevators and rudder. This way, initial control stick inputs from the pilot result in small servo
movement for a smoother flying airplane.
Mixing -
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 (WING mixing) in the transmitter. When servos are
electronically joined via programming, they are said to be
“
mixed.
”
Each servo
’
s end points can be independently set.
