V-TAIL (VTL)
This function
automatically sets up the PCM
1024Z to control a V-tail sailplane with com-
bined elevator and rudder functions. It requires
two
servos,
one
hooked
up
to
receiver
output
CH2
(elevator 1/rudder 2) and the second plugged into
CH4 (elevator 2/rudder 1). The elevator and rud-
der deflections can be adjusted independently.

Setting the Elevator Rates - 1 and 2
Begin by
setting
the
rate
for
Elevator
1.
Press the B
key to activate rate setting for Elevator 1 and set the rate
with
the numeric
keysE to M.
The number
keys 0

100
input the value directly. The + and -
keys increase or decrease the value by 1. The
+/-
key
may be used to reverse the throw direction.
If you are not sure what you are changing, hold the
stick to one side and press different keys — if there is no
effect, move the elevator stick to the other side and con-
tinue. Your setting may vary from —100 to +100%. the
initial value is set to +50%.
Now set the rate for Elevator 2. Press the
Q
key to
activate Elevator 2 rate setting and set the rate with the
numeric keys as before.
Setting the Rudder Rates - 1 and 2
You now set the rate for Rudder 1. Press the C key
to activate rate setting for Rudder 1 and set the rate with
the numeric keys E to M as before.
If you are not sure what you are changing, hold the
rudder stick to one side and press different keys — if there
is no effect, move the rudder stick to the other side and
continue. The initial value is +50%, but your setting may
vary from -100 to +100%.
Now set the rate for Rudder 2. Press the P key to
activate Rudder 2 rate setting and set the rate with the
numeric keys as before.
Checking Your Work
After you have set up the V-Tail rates, be sure that
they move the correct directions. For up elevator com-
mand, both V-tails should move upward. For right rudder
command, the trailing edge of both surfaces should move
to the right. If they do not, use the
+/-
to reverse the
direction as needed.
Use the
END ( N )
key to leave this menu.
