This may show up as E-F.D
unless you hold up elevator.
Step 11. Mixing elevator to flap: With the flap switch in the
upper position, press the Up key until “MIX E-F.U” appears on
your screen. This is the elevator-to-flap mix. Press the CH key to
access the “EF: SW”screen. This screen allows you to select
which switch will be used to turn on/off the elevator to flap
mixing. Pressing the (+) key will select one of the following
switches: MX SW = mix switch (located on the back right of the
transmitter), F-DN = flap switch down, F-UP = flap switch up, or
ON = always on. We suggest selecting the mix switch MXSW so
the elevator-to-flap mix can be turned on and off independently
of the flaps. After selecting MXSW, press the CH key to access
the “MIX E-F.U” screen. With the Mix switch in the forward
position, hold up elevator and press the (+) key until a 35%
value is achieved. Up should result in down flaps. If the flap
goes up, then reverse the 35% value from a +35 to a -35 using
the (-) key. Now hold down elevator and press the (+) key until
35% is achieved. The flaps should go up. Reverse the value if
necessary until up elevator gives down flaps and down elevator
give up flaps. Later you can experiment with more or less flap
throw by changing this value. 35% is a good, safe place to start.
Note: The XP347 doesn’t allow the elevator-to-flap mixing to
be assigned to another switch and it remains on the
flap up position.
Step 12. Aileron to flap mixing: Press the Up key until the
mix “AL-F” (aileron- to-flap mix) screen appears. Press the CH
key to access the “MIX AF: SW” screen. This screen allows you
to select which switch is used to turn on/off the aileron-to-flap
mix. Pressing the (+) key will select one of the following switches:
MXSW = mix switch located on the back right of the transmitter,
F-DN = flap switch down, FU+D = flap switch up and down, and
ON = always on. We recommended putting the aileron-to-flap
mix on the mix switch so the mix can be turned off independent-
ly from the flaps. After selecting MXSW, press the CH key to
return to the “MIX AL-F” screen. Now press the (+) key until
+100% value is reached. Now the flaps should move in unison
in the same direction with the ailerons. If they move in opposite
directions, press the (-) key until a -100% value is reached.
Note: When programmed, the aileron-to-flap mixing is
always on when using an XP347.
Note: If “OFF” appears (where the mixing value is located in
our example) move the flap switch to the opposite
position. If “OFF” is still on the LCD, move the mixing
switch to the opposite position.
