ELEVATOR MIXER
For models with a V-tail the functions of elevator and
rudder must be mixed so with one another so that
during elevator movement both surfaces are moved
up or down in the same direction, and during rudder
control the surfaces move in opposite directions , i.e.
one surface upward and the other downward. The
"VTL" Program contains the appropriate mixer, to
control surfaces connected to separate servos. The
function is activated using the INC / DEC buttons.
Servos connected to outputs 3 and 4 of the receiver
are automatically coupled with one another. The mix
relationship is changed using the dual- rate setting,
see page 20, where Ch4 changes the rudder effect
and Ch3 the elevator effect.
It is usually necessary to adjust the elevator when
altering the spoiler setting due to the change in lift
created by the wing.
This codes allows the elevator to be adjusted to suit
the position of the spoiler stick (control function 1)
during the landing approach, within the range of 0 to
±125%.
The mix proportion is determined using the code "S-
E" and pressing the INC / DEC buttons.
Pressing the CH SEL button switches to the offset
setting:
The mixer must be programmed, which position of
the spoiler control (throttle / spoiler control stick 1)
corresponds to normal flight. This would be the
position with the spoilers retracted and therefore the
neutral position of the elevator. To set this offset, the
control is moved to the appropriate position and the
CLEAR button is pressed. The offset, the deviation
from the control centre position, is indicated in the
display.
Using a switch connected to socket 7 of the
transmitter board this function can be switched off.
