- Press the "S" button again;"%" flashes.
- Turn the 3-D hotkey,and you can set the mixer value you wish to
use;50% is a good starting point.
- Check that the rudder moves to the right when you give a "right
aileron" command (right aileron up).
- If that is not the case,turn the 3-D hotkey left to set a negative
mixer value of -50%.Check the function again.Holding the 3-D
hotkey pressed in for 1 second reverts to the default value of
50%.
8.4 Wing mixers (WING)
This menu point groups together various mixers involving the
control surfaces on the wings,and offers a very convenient method
of setting them up.
FLPN sub-menu: with this function you can add differential travel
to the two ailerons, and also (optionally) set up the ailerons to rise
together to work as spoilers; this function is known as a flaperon
mixer (flap + aileron = flaperon).
In the ELVN sub-menu you can activate a pre-programmed mixer
for delta or flying wing model aircraft.
The flow chart below provides an overview of the individual sub-
menus to help you find your way around.
Explanation of terms:
Since the mixer inputs for the wing flap travels can be set separately
for "up" and "down",the ailerons can be used for several functions;
their function varies according to the flap travel:
- Large deflection up -> spoilers
- Small deflection up -> speed flaps for high-speed flying
- Large deflection down -> landing flaps
It is possible to program the wing flap deflection in the same
direction for both sides of centre;for example:large "up" deflection
as spoilers, at the other extreme only slight "up" as speed flight
trim.
To help you understand and emulate the following
adjustments,we recommend that you set up a model with two
aileron servos (sockets 1 and 6),or just two servos on their own,
and observe the effects of the mixer on the model.
Flaperon mixer FLPN
- Move to the Select menu "WING".
- Press the 3-D hotkey,and the display "INH" (Off) appears; the
flaperon and delta mixers are switched off.
- Turn the 3-D hotkey to the right,and the Setup menu FLPN
appears;confirm by pressing the "S" button,and the display "SET
%" flashes.
- The two aileron servos (channels 1 and 6) are now mixed
together;the flap function (FLPN) is also active,and aileron
differential is set to the default of +50%.
- The FLPN function can be operated over its full travel by
means of a transmitter control (e.g.linear slider) connected
to channel 6.
- Check the "sense" of the aileron system:when you move the
aileron stick to the right,the right-hand aileron should rise,the
left aileron fall.If one or both servos runs in the wrong direction,
reverse it in the Setup menu "REVR".
- Check also that the travel of the down-going aileron is now
smaller (correct differential).
If this is not the case, i.e. the travel of the up-going aileron is
smaller, press the "S" button.The "+" prefix now flashes; rotate the
3-D hotkey to the left, and the prefix changes to "-", which reverses
the differential.
0% No differential
50% Differential by half the maximum travel
100% "Split" mode:only the up-going aileron moves
If you connect an external mix trimmer to Pin 4 (see Section 8.2)
the differential value can be over-ridden by +/- 25%; this enables
you to set the correct differential in flight.
If you connect an external mixer switch to socket 7, you can
switch off differential in flight, which produces greater aileron
response for the landing approach.
Holding the 3-D hotkey pressed in for 1 second restores the default
differential value (+50%).
Selecting the 2nd aileron output (CH)
Pressing the "S" button again activates the menu in which you can
select the output to which the second aileron is to be connected.
The default arrangement is channel "6".
Turning the 3-D hotkey to the left switches it to channel "7".
If you select channel 7 for the
second aileron output, the wing
flpn mixer function is automatically
switched off.
If you connect a transmitter control,e.g.a linear slider,to channel 6,
it acts as a normal transmitter control on servo channel 6.
This is the correct setting for model aircraft which require aileron
differential,but no superimposed flap function for the ailerons.
The second aileron servo must be connected to receiver output
7;re-connect the servo if necessary.
