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

Setting the Elevator Rates - 1 and 2
You now set the rate for Elevator 1. Press the B key
to activate rate setting for Elevator 1 and set the rate with
the numeric keys E to M . The number keys 0 through
100 input the value directly. The + and - keys in-
crease 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 +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.
