STEP 2: AUTO BALANCE MODE CHECK
Place the plane on a horizontal surface with both the wings and pitch leveled. Centre the rudder
surface. Move the 3-position switch so that the FY-20A is in the
Auto Balance Mode
.
STEP 3: AILERON CHECK
•
Incline the plane to the right (roll right). The ailerons should give a control signal to counter this
roll direction (see below). Similar action should occur when rolled to the left. If the ailerons move
correctly, the knob has been turned in the correct direction. You can now adjust gain by moving
nearer (low gain) or further
away (high gain) from
center:
•
If the ailerons do not
follow
the
movements
shown above, simply turn
the aileron knob to the
opposite
side
(beyond
centre). You should now
see
the
correct
servo
movement.
STEP 4: ELEVATOR CHECK
•
I
ncline the plane NOSE
UP. You should see the
elevator move down.
And when you move the
NOSE
DOWN,
the
elevator should move up.
Move the Elevator knob
to the opposite side
(from Centre) if the
servo
movement
is
incorrect:
•
Adjust Elevator gain according to your
aircraft requirement (lowest gain nearest to
centre, highest gain further away from
centre).
STEP 5: RUDDER CHECK
•
Rotate the plane at its centre axis from left
to right. You should see the following
action:
•
Move the Rudder knob to the opposite side
(from Centre) if the servo movement is
incorrect:
•
Adjust Rudder gain according to your aircraft requirement (lowest gain nearest to centre, highest
gain further away from centre).
STEP 6: FLIGHT TEST AND SENSITIVITY ADJUSTMENT
•
Steps 1 to 5 should enable you to correctly set your servo movement direction via the 3 knob dials.
•
To fine tune your aircraft attitude control via the FY-20A, some flight testing has to be performed.
•
For the first flight it is recommended that the gains not be set too high. This will reduce large
oscillation or
‘
flight overcorrection
’
.
•
After the flight take off, switch the device from Mode 1 (deactivated) to Mode 3 (Auto-balance
mode).
•
If you see oscillation of the wings, this indicates the Aileron gain is set too high. Switch back to
manual mode and land the airplane. Reduce the sensitivity (move dial towards centre position) and
fly again. You should see improvement in wing attitude. Adjust until you are satisfied with the
level of wing stabilization.
•
Too much Elevator gain will show the tail moving up and down (rocking). Too much Rudder gain
will show tail wagging. Reduce gain until this flight overcorrection is gone.
•
Alternately, if you find the flight correction is not enough, you can increase gain accordingly.
WARNING: SAFETY PRECAUTION
–
MUST READ
i.
The purpose of the FY-20A (FSS) is to stabilize the aircraft. It is not an Anti-Stall device. The
stabilization action of the FY-20A will fail if the aircraft is stalled.
ii.
The aircraft direction is controlled by you, at all times. Make sure you know where you are going.
iii.
The FY-20A is for your enjoyment. Do not fly the plane into a crowded area, where your aircraft
can cause serious injury if it were to crash. Please be responsible when using this product.
iv.
Besides the regular pre-flight checks (we recommend a checklist), always check the correct
operation of the stabilizer on the ground prior to take off.
v.
Any electronic hardware on an RC aircraft can fail over time. Please assess your aircraft and
electronics condition before use. We are not responsible for any losses as a consequence of using
this product.
vi.
Please ask an experienced RC Plane pilot for assistance if you are a beginner. It is absolutely
critical that you get flight basics before proceeding. You also need directions to correctly assemble,
take off and control your RC Model. We highly recommend joining your local RC Modeling club.
vii.
Never fly close to people, buildings, wires, vehicles, trees or closed spaces. You could seriously
injure someone.
viii.
Minimum flying distance should be 20 feet from yourself or others. Learn about emergency
procedures should you lose control of your aircraft.
ix.
Keep the RC Model and the related equipment away from children. RC planes are not toys.
Children must be supervised at all times if they are allowed to fly.
x.
Please operate your RC plane within the permitted area of your local government. For more details,
please check with your local council or government.
xi.
If you are not using 2.4 GHz spread spectrum radio, never turn on your radio before checking and
re-checking that you're the only one using the frequency. You could cause a crash of another
aircraft if the frequency is the same. For security; please obey to the local frequency regulation.
xii.
Never use the remote control within three miles of your local airport. You could endanger full scale
aircraft instruments. Lives could be lost.
xiii.
Keep all electrical equipment away from rain water, moisture and extreme high temperature.
xiv.
DO NOT OPEN any FY-TECH Attitude Flight Stabilization System (AFSS) unit or any of our
other modules. Opening or dismantling the module cover will null any kind of warranty we and our
distributor have on the product you purchased.

FY-20A Installation
Use double-sided taped Velcro to stick the FY-20A inside the
plane. We highly recommend using the included vibration
damping platform.
Install the FY-20A Horizontally. Ensure that you install the
unit with the Arrow pointing towards the aircraft nose
(direction of flight). Also ensure that the receiver is fixed
firmly.
G.
Set CH5 to to any 3-position switch on your transmitter
(to select 3 modes control) or 2-position switch (to activate
or deactivate FSS only).
H.
Turn on your transmitter and connect power to your
plane(Be sure to remove the propeller!).
a.
Adjust the three dial knobs. Turn all in one direction.
b.
Switch the FY-20A to Mode 3 (Auto Balance Mode) via
the SE switch.
c.
Check for the correct movement direction of each servo
d.
Reverse dial knob rotation if servo counter movement is
not moving correctly.
e.
Aileron
: if the plane rolled left ,the FY-20A stabilizer automatically moves the aileron to roll
right. If plane is rolled to the right ,the FY-20A stabilizer automatically counters to roll the
plane to the left. If the control direction is wrong, rotate the AIL dial knob in the opposite
direction.
f.
Elevator
: if the plane nose is pitched up, the FY-20A stabilizer automatically moves elevator
down. If the plane is pitched down ,the FY-20A stabilizer automatically moves the elevator
up. If the control direction is wrong, rotate the ELE dial knob in the opposite direction.
g.
Rudder:
If the plane's nose is rotated to the right rapidly, the FY-20A stabilizer automatically
moves the rudder to the left. If the plane's nose is rotated to the left, the rudder will
automatically move to the right. If the control direction is wrong, rotate the RUD dial knob
in the opposite direction.
h.
Check that the FY-20A is installed firmly on the vibration-absorbing mount. Close the
cockpit. Installation is completed. Test fly to adjust gain.
