7.1 Disarm & Arm
After completed the calibration, click on “FC test” and click “Test”
button. If no further error notification, you may proceed for arming. If
any error message shown, you need to re-calibrate it before you’re
able to arm.
To arming P2 Pro, just put the throttle stick to bottom, rudder to right,
aileron to left, elevator to bottom, hold for 3 seconds.
For most left hand throttle or right hand throttle, switch the mode
switch to Stable mode, keeping the aircraft static, adjust the remote
controller sticks as shown in pic 1 for at least 3 seconds to arm. Adjust
the controller sticks as shown in pic 2 for 3 seconds to disarm it. After
arming, if the throttle stick is in minimum position for 3 seconds or
longer, P2 Pro flight controller will automatically locked the aircraft. If
arming in GPS mode, good GPS signal is needed to arm the aircraft.
Suggest arm in Stable mode and switch to GPS mode after arming.
Pic 1 Pic2
Caution: After the aircraft landed, please disarm the aircraft to prevent
the unintentionally touch on throttle stick, which can caused serious
injuries.
7.2 Stable Mode (Attitude Mode)
Switch the remote controller CH5 to Stable mode, arm the aircraft, and
increase the throttle softly till the aircraft lift up the ground (depend on
your throttle setting), the aircraft will take off steady. Thanks to advance
algorithm of P2 Pro Flight controller, during the indoor or breeze-less

condition, you can get the stable hovering flight or excellent fixed height
flying.
Caution: 1. GPS/Compass module is not working in Stable mode flight.
2. The throttle control way is different between Stable mode and GPS
mode, please pay attention to throttle control when switching between
these 2 modes.
7.3 GPS Flight Mode
7.3.1 GPS Mode
Choose an open area outdoor where do not have any high-rise building
and no magnetic interference environment, connect the aircraft with
power, LED light shall double blink to entering satellite searching mode,
wait about 1 minute, when the LED change to slow blinking, the satellite
searching is completed and the position locating is successful.
Switch the remote control CH5 Stable mode to GPS mode position and
arm your aircraft (user can also switch stable mode to GPS mode during
flight), increase the throttle to 50% and above to make the aircraft
lifting from the ground, aircraft shall be lifting vertically. After the
aircraft reaches the desired altitude, keep the throttle at 50% level, the
aircraft shall hovering at the height automatically, if the user adjust the
aileron and elevation, the aircraft will fly at the keeping height.
Caution: Compass module is involved as assist when P2 Pro flight
controller working under GPS flight mode, you must stay away from
strong magnetic field. While the GPS module is also involved in this
mode, you need to choose a good GPS, and Satellite signal area (shall
stay away from high rise building).
7.3.2 Go Home under GPS mode
P2 Pro flight controller will record the location where the user arm the
aircraft as home location, switch your remote controller CH6 to Go
Home mode, the aircraft shall automatically lifting to 20 meter height,
keep the previous flying course and fly back to home location. During
the return flight, aircraft will not be controlled. Once the aircraft reach
the home point, it will hover at the air for about 2 seconds before
descending slowly, in this period you can adjust transmitter stick to

www.jiyiuav.com
adjust the landing point (but throttle is not working). After the aircraft
landed, the motor shall spin slowly and stop. User shall put the throttle
at minimum level, the flight controller will automatically disarm after 3
seconds.
Caution: 1. The precondition of Go Home is GPS module records the
home point location (The location of arming) successfully. Home point
may be not recorded correctly if armed in stable mode. Suggest to arm
under GPS mode if you need to use Go Home.
2. To prevent from any injury, when the aircraft is near to human, it is
advisable not to switch to Go Home mode.
7.4 Smart Circling Mode
Make sure with good GPS signal during the flight, switch the
remote controller CH5 to IOC to enter Smart Circling mode. After
switch to Smart Circling, the aircraft will not start to circle flying
immediately, first it will be hovering, then start to circle flying,
default circle center is 10 meter away from nose of aircraft. In this
mode, radio controller only control the aircraft flying radius and
speed and will not control the flying direction. Please see below
compare table of GPS mode and Smart Circling mode:
GPS Mode
CH1
Control the roll of aircraft (ROLL)
CH2
Control the pitch of aircraft (PITCH)
CH3
Control the altitude of aircraft (ALT)
CH4
Control the yaw of aircraft (YAW)

www.jiyiuav.com
CH1 controls the aircraft circling speed and direction. When the
aircraft hovering, move stick to left, aircraft will start circling with
default radious (10 meters) clockwise. Keep stick on left, the
circling speed will become faster. The speed increase is decided by
the controller stick. Stick returns to center, the aircraft will be
circling at current speed. Stick moves to right, aircraft circling
speed will slow down till stop (hovering). Keep stick on right, the
aircraft starts circling counter-clockwise. The control way is the
same as clockwise circling.
CH2 controls the circling radius. Moving the stick up, the circling
radius will decrease. Moving the stick down, the circling radius will
increase. Stick in middle, aircraft keeps current radius circling.
When the circling radius is 0, the aircraft is in pan-shot mode, it will
be hovering and rotating. CH1 will control the rotating speed and
direction.
Caution: 1. Do not take off in Smart Circling mode to prevent accident,
because the control way is different with Stable and GPS mode.
2. Before switch to Stable and GPS mode, please make sure you are
clear about nose of aircraft, to prevent from any accident because
of not clear of nose of aircraft.
