EXP1 = 3-POINT CURVE (EXPONENTIAL)
The “EXP1” function is used to alter the characteristic curve of the transmitter
control into a non-linear (exponential) curve, symmetrical around the centre point.
The exponential curve can be applied in either direction.
•
Positive prefix:
strong control response around the neutral position, reducing
towards the end-points.
•
Negative prefix:
weak control response around the neutral position, increasing
towards the end-points.
To change the degree of exponential simply press the button field
“EXP A”
or
“EXP
B”
and enter the appropriate value.
For a simple symmetrical setting activate the
“Separate.”
button field and select
“Combine.”.
The end-points are altered using
“Rate A / B”
.
OFFSET
The Offset setting changes the neutral position of the transmitter control relative to
the servo centre point. If the offset value is up to 50%, the travel remains the same
for both sides of neutral, but if the value is any higher, the servo travel will be at its
end-point at one extreme, so the travel becomes increasingly asymmetrical.
EXP2 = 2-POINT CURVE (EXPONENTIAL)
The “EXP2” function is used to alter the characteristic curve of the transmitter
control in a non-linear manner between the two end-points.
The exponential curve can be applied in either direction.
•
Positive prefix:
upward curve.
•
Negative prefix:
downward curve.
Press the button field
“EXP”
and set the value.
For a simple symmetrical setting activate the
“ Separate.”
button field and select
“
Combine.”.
The end-points are altered using “Rate A / B”.
OFFSET
The Offset setting changes the neutral position of the transmitter control relative
to the servo centre point. If the offset value is up to 50%, the travel remains the
same for both sides of neutral, but if the value is any higher, the servo travel will be
at its end-point at one extreme, so the travel becomes increasingly asymmetrical.
VTR = 5-POINT CURVE (VARIABLE TRI-RATE)
The VTR curve is a variable 5-point curve which divides the transmitter control
characteristic curve into two gradients, symmetrically around the zero point. In
principle this equates to linear travel reduction (Dual Rate), but in this case the
servo still reaches maximum travel at the end of the transmitter control travel.
Setting:
•
First set the transmitter control reduction using
P.RATE A / P.RATE B
, for exam-
ple 50% = 40% of travel.
•
Now define the “elbow” point using
P.POS A / P.POS B;
around 85% is a good
starting point.
•
If necessary adjust the end-points using
Rate A / Rate B.
For a simple symmetrical setting activate the
“ Separate.”
button field and select
“
Combine.”.
