Advanced GPS flight controller manual ( Applies to GPS-equipped aircraft only)
Precautions:
Features
Functions
1. If you are an inexperienced pilot, seek the assistance of a flight instructor to help you with setting up your
aircraft. As R/C models are not toys, improper setup and/or operation may result in serious accidents or injuries.
2. Please follow all rules and regulations when flying your aircraft as local regulations may differ from region to
region.
3. Always check that your R/C system has enough range. Perform a range check by moving the control sticks and
aux channel while walking away from the model. The aircraft should respond within 50 steps.
4.Ensure that the battery provides sufficient power. When the low voltage alarm sound and orange power indicator
light flashes, replace the radio control battery, to ensure safe aircraft operation.
5.The FMS F4 2.4GHz transmitter pairs only to its own receivers. Receivers made by other manufacturers will not
function with the FMS transmitter.
1.Flight components include a 32 bit processor, 3 axis accelerometer and 3 axis MEMS gyroscope, high accuracy
GPS chip integrated with a2.4GHz receivers and 12A brushless ESC
2.Controllable via a 3 position switch on the transmitter which allows the system to switch between stabilized,
optimized and off modes
3.GPS return to home, fail safe and flight perimeter fence functions built in.
1.Pairing: With the transmitter turned on, power on the aircraft. Press and hold the bind button on the transmitter
for 3 seconds to begin the pairing sequence (Skip if the aircraft is already paired to the transmitter).
2.Automatic systems check: With the aircraft and transmitter powered on, keep the aircraft level on the ground and
keep both control sticks at their neutral position. The elevator will pitch up to signify that the aircraft is trying to
obtain a GPS signal (NOTE: Ensure that the aircraft is flying at a wide open location, otherwise the GPS calibration
will fail. If the GPS functionality is not needed, press and hold the return to home button on the top left hand corner
of the transmitter for about 3 seconds to cancel and turn off the GPS function. If the GPS function has been
successfully turned off, the elevator will cycle twice then return to its neutral position- signifying that the aircraft is
ready to fly). The white status LED at the nose of the aircraft flashes when the aircraft is searching for a GPS
signal. When a GPS signal has been found, the status light will turn solid. 3-9 seconds after the GPS signal is
found (in which time the GPS system is verifying a stable signal), the elevator will cycle twice and return to neutral-
signifying that the aircraft is ready for GPS flight. NOTE: If the aircraft has is being flown at a new location or if the
aircraft hasn’t flown in a while, the GPS system will take longer to verify its position.
3.GPS status LED: Under GPS mode, the status light flashes rapidly when the system is searching for satellites.
The status light turns solid once a GPS signal has been found. If the aircraft is not flying under GPS mode, the
status light then indicates the aircraft’s current flight mode (Solid=stabilized, slow flashes= gyro off, fast
flashes=optimized).
4.Stabilized mode: Triggered using the three position switch (outer position) on the transmitter, the aircraft returns
to level flight whenever the control sticks are at their neutral positions.
