Opterra® 1.2M
Transmitter Setup (BNF)
SAFE® Plus Technology (BNF with FPV)
There are three confi gurations for the Opterra 1.2m aircraft. A PNP option
(EFL11475) requires pilots to install their selected control and FPV systems.
A BNF Basic package (EFL11450) offers the proven SAFE
®
and AS3X®
technologies and does not include any FPV equipment or GPS features. The
BNF Basic with FPV package (EFL11460) includes SAFE Plus technology which
adds GPS based features to airplanes for advanced drone-like capabilities. GPS
also enables an On Screen Display (OSD) system to show helpful information
for the fl ight on top of the video image.
In addition to making the airplane generally stable and easy to fl y, SAFE Plus
technology can keep the airplane within the fl ying area, let the pilot have
time to think while the aircraft cruises in a holding pattern, and it can land
the aircraft automatically. No complex programming is required for AutoLand,
Holding Pattern, and Virtual Fence.
When fl ying in beginner mode, the airplane has sensors to prevent aggressive
maneuvering. In that mode, limitations keep the pilot from over-controlling, and
automatic self-leveling makes recovery from risky or confusing attitudes as
simple as releasing the sticks.
With Virtual Fence the airplane uses GPS technology to prevent the pilot from
fl ying too far from home. If the airplane passes the Virtual Fence, the model
will turn around to fl y home by itself. Control is returned to the pilot when the
airplane is within the Virtual Fence again.
Engage Holding Pattern or Loiter mode to enjoy a cruise around the fl ying area,
the model will continue to circle the area in Holding Pattern or Loiter mode
with no pilot commands. When it’s time to land, AutoLand brings the airplane
down and performs an automatic landing with no pilot assistance, right at the
designated home location.
Safe Plus technology fl ight modes are selected at the fl ip of a switch and
include an intermediate mode and advanced mode. Experienced pilots can fl y
without restraints in the AS3X fl ight mode. When fl ying in the AS3X fl ight mode,
self leveling features are disabled.
IMPORTANT: The included receiver has been programmed
for operation specifi cally in this aircraft. The programming
in this receiver cannot be changed by the user.
• SAFE Plus Flight modes are selected using Channel 5
IMPORTANT: A transmitter with a 2-position Channel 5
switch will only allow the use of position 0 or position 2
fl ight modes. If possible, assign the Gear channel (CH 5)
in your transmitter to a 3-position switch to operate all 3
fl ight modes.
• The Aux 1 channel (CH 6) is used for AutoLand and
should be assigned to a momentary button (I button/
Bind Button)*
Refer to your transmitter manual for more information
regarding switch assigning.
* The Opterra 1.2m aircraft is not compatible with DX4e or
DX5e transmitters.

** BNF with FPV only
The fl ight control system included with BNF versions is compatible with the
CRSF protocol for alternative receivers. Connect the receiver to the CRSF
port and follow the manufacture’s instructions for binding. The fl ight control
system will automatically detect CRSF receivers when connected. Always
verify correct control surface response to control inputs before fl ight.
CRSF compatibility
CAUTION: Elevon mixing is handled in the fl ight controller.
Do not use an elevon mix with the BNF Basic fl ight
controller or you may experience loss of control. Loss of control
could result in a crash causing personal injury or property damage.

CAUTION: Connecting the battery to the ESC with
reversed polarity will cause damage to the ESC,
the battery or both. Damage caused by incorrectly
connecting the battery is not covered under warranty.
IMPORTANT: The included receiver has been programmed
for operation specifi cally in this aircraft. The programming in
this receiver cannot be changed by the user.
Refer to your transmitter instructions for binding to a receiver.
The throttle will not arm if the transmitter’s throttle stick is not
put at the lowest position and the throttle trim centered or lower.
Binding Procedure Reference Table
1. Make sure the transmitter is powered off.
BIND
2. Make sure the transmitter controls are neutral, the throttle
is at the lowest position*, the throttle trim is centered and
the aircraft is immobile.
3. Insert a bind plug in the receiver bind port.
4. Connect the fl ight battery to the ESC. The ESC will produce a
long tone followed by a series of additional short tones.
5. The receiver LED will begin to fl ash rapidly.
6. Power on the transmitter while holding the transmitter bind
button or switch.
7. When the receiver binds to the transmitter, the red bind light on
the receiver will turn solid and the ESC will produce ascending
tones. The tones indicate the ESC is armed, provided the
throttle stick and throttle trim are low enough to trigger arming.
8. Remove the bind plug from the bind port. The receiver should
retain the binding instructions received from the transmitter
until another binding is done.
9. Disconnect the fl ight battery.
10. Safely store the bind plug (some owners attach the bind
plug to their transmitter using two-part loops and clips).
* The throttle will not arm if the transmitter’s throttle stick is not put at the lowest position.

Consult local laws and ordinances before choosing a
location to fl y your aircraft.
In order to have the most success and to protect your
property and aircraft, it is very important to select a place
to fl y that is very open.
Remember, your aircraft can reach signifi cant speeds
when fl ying and can cover ground quickly. Plan on fl ying
in an area that gives you more space than you think you
need, especially with fi rst fl ights.
The site should:
• Have a minimum of approximately 1300 feet (400m)
of clear space in all directions.
• Be clear of people and pets.
• Be free of trees, buildings, cars, power lines or anything
that could entangle your aircraft or interfere with your
line of sight.
Choose a Flying Field
Perform the compass calibration outdoors before the fi rst
fl ight or to correct the heading during auto landing if it
varies signifi cantly from the heading set during takeoff.
1. Remove the propeller if it is installed or activate
throttle cut.
2. With the transmitter trims centered, power on the
transmitter and the aircraft while holding the transmitter sticks as shown. The aircraft will indicate the
GPS is searching for satellites by cycling the elevator
up and down.
3. After satellites are acquired, the aircraft will signal
it has entered compass calibration mode by the
following:
Wings on: The elevons will cycle up and down slowly.
Wings off: The red and blue LEDs on the fl ight
controller will fl ash alternately.
Once in calibration mode, the throttle is not active and
the transmitter sticks can be released. The transmitter
must remain powered on.
4. Once in calibration mode, rotate the aircraft twice in
position 1.
5. Turn the aircraft 90 degrees and rotate it twice in
position 2.
6. Turn off the transmitter.
7. Wait 3 seconds and disconnect the fl ight battery.
Compass Calibration Procedure (BNF with FPV)
EN
9
The video transmitter installed in the BNF FPV version includes an integrated
On Screen Display system (OSD). The OSD takes advantage of the GPS data
available on the aircraft to deliver the pilot useful information on the video
display. The OSD shows the Flight Mode, Speed and altitude, GPS status,
distance to home and an arrow pointing home, time aloft, and voltage. A call
sign is also available on the OSD, it is recommended to display your HAM call
sign to satisfy amateur radio rules.
The OSD is also helpful during prefl ight setup because it will tell the pilot the
status of GPS systems. It will tell the pilot when the model has a suffi cient GPS
lock and is ready to fl y.
The video transmitter frequency and power output can be set directly from
compatible Spektrum transmitters or set in the OSD menu.
OSD Menu
The OSD has a menu system which has options where the pilot can make
changes.
1. To enter the menu the motor must be disarmed.
2. Flip the fl ight mode switch back and forth twice to enter the menu.
3. To navigate the menu use elevator stick to move up and down through
the menu, and aileron stick to move side to side through the menu.
