AUTOMATIC FLAP POSITIONING
OPERATES ON +12V & +24V SYSTEMS
COMPATIBLE WITH MOST MOTORS
* Set-Up is FULLY user PROGRAMMABLE!

NO LIMIT SWITCHES TO INSTALL & ADJUST
The FPS-Plus-nt has two modes
of operation, and one mode for programming.
installation, it will be up to the user to decide which one of the four modes
that the FPS-Plus-nt will operate.
MODE 1 - (Proportional manual flap operation
Flap moves only
when flap button is pressed. You must keep holding the button for the flap to
MODE 3 - (Automatic step flap mode)
Flap moves from
programmed flap stop to flap stop. One press less than 1 second (Short Press)
begins the movement, up or down. Hold the flap button for more than 1 second
(Long Press), and the flap will go all the way to its end stop. The direction
will be towards the button pressed, flap up, or flap down. If the flap is
moving, to stop it, simply press the opposite command. The flap movement will
MODE 5 - (Used for programming all flap stops.)
One Touch Operation
In the fully automatic mode
(mode 3), a “one button touch”, commands the flaps to
move. This “one touch command” moves the flap from one programmed flap stop, to
the next programmed flap stop. Holding the button down for more than 1 second
commands the flap to go to either the full up, or the full down positions. If
you decide to abort going to a flap position after you gave a command to do so,
just give it an opposite command. The FPS-Plus will stop the control surfaces
from further movement.
Installation is easy!
The only items you'll need, is the FPS-Plus-nt, a flap motor assembly, and one position sensor
for the flaps. If you want the position of
the flaps to be displayed on your panel, you'll need a
position indicator as well.
You can utilize most motors,
position sensors, and position indicators that are on the market today. If
you want to retrofit the FPS-Plus-nt to your already flying aircraft, you may.
You don't have to install any limit switches to your flap system. The
FPS-Plus utilizes the output from your "already existing" flap & elevator trim
position sensors. Some motor assemblies, like the
Ray Allen Company's
motors, already have built-in position sensors.
Installing Position Indicators with the FPS-Plus-nt:
want to use a position indicator with the FPS-Plus, please read on.
Position indicators that are presently sold by various companies, have very
different input signal requirements. Some companies have two or more
different input ranges. It is unfortunate that no standard exists for
these indicators. In order to utilize the wide variety of position
indicators with the FPS-Plus-nt, Aircraft Extras, Inc. has developed a small add-on
pc board that will also be supplied with each FPS-Plus-nt, at no extra charge.

FPS-Plus in mode 5. Position your flaps where you want them, and press the
program button. You may store from 2 to 10 intermediate flap positions, your choice.

positions by default.)

What else do I need to complete the FPS-Plus-nt
Does this system come complete with control motors,
position sensors, or position indicators?
the good news is; you can connect it up directly to most small aircraft that are
flying today, or design it into your present aircraft project. The
Ray-Allen Company's systems and other flap motor actuators systems from
Vans Aircraft are all
Are the Ray Allen Company’s servos and position sensors
compatible with this system?
YES - The servos
even have a potentiometer built into them for position sensing.
Are the Ray Allen Company’s position indicators
compatible with this system?
YES - We provide
a small PC board that is used to interface between the FPS-Plus, and the
position indicators. One
board will drive two position indicators. See the explanation under
Can I retrofit my flying plane with the FPS-Plus-nt?
YES - This might
take a little rewiring, but is WELL worth the effort. Probably your biggest
challenge, is to find another place to install a redundant flap switch, if you
don’t have one already have one installed in your bird.
Can I use the FPS-Plus-nt on non-clutch driven flap
motors with limit switches?
YES - You will
need to connect it to the flap motor a little differently. The following
schematic should help for pre-planning.
