CIRCUIT BREAKER/SWITCH
Instead of a switch and a separate in line fuse, you might want to consider a circuit
breaker/switch. Use a fast acting (NOT instantaneous) 3 amp magnetic circuit
breaker/switch (2 amp for 28V systems).
Carlingswitch (call (203) 793-9281 for nearest distributor) makes a nice looking, gray
colored, lighted, 3 amp rocker switch that snaps into a rectangular cutout. The part
number is MF1-B-32-430-1-JC2-7-A. Each section of this long part number indicates a
different option—you might want to get a catalog and change, for example, just the color
of the light (this one has a green lens).
Or you may prefer the convenience of round hole mounting a similar sized black lever
switch available from the Airpax division ofPhillips Technologies (call (410) 228-4600
for nearest distributor, part number Tl 1-1-3.00A-OI-10A-V).
PREFLIGHT CHECK
Set the TURN CONTROL to midrange and make sure it is in the center dead zone. To do
this, set the AP-1 to WL mode (flip Mode Switch right) and slowly rotate the TURN
CONTROL from stop to stop at a constant speed. You will hear the servo pause as the
knob passes through the dead zone. If you do the same thing while you are flying, the
wings will momentarily stop rolling as the knob goes through the dead zone.
Set the TRIM and TURN CONTROLS to midrange. Set TRIM RANGE, LEFT CAL, and
RIGHT CAL trimpots to midrange. Leave the GYRO NULL trimpot alone. Set the SPAN
trimpot fully clockwise (Note: the servo range goes to zero when the SPAN trimpot is
fully counter-clockwise). Put a small screwdriver in your pocket for adjusting trimpots in
flight.
Put the autopilot in Wing Leveler mode (Mode Switch to right) while taxiing. Make a
right turn, and you should feel the stick move to the left, and vice versa. A right should
give left aileron. The servo must always work against whatever the airplane is trying to do
on its own.
BE DAMN SURE YOU CAN OVERRIDE THE SERVO ANYTIME YOU WANT!
Test the override by pushing the stick both left and right.
DISENGAGE THE AUTOPILOT BEFORE TAKEOFF.
The servo is disengaged only when the Mode Switch is in its center position. The turn
coordinator always operates, no matter what position the Mode Switch is in.
