For safety reasons, if you’re using your own transmitter and receiver in the Kit or Receiver-Ready versions, you
MUST REMOVE THE PROPELLERS BEFORE CALIBRATING THE GYROS,
INITIALIzING THE FLIGHT CONTROLLER, AND ARMING THE MOTORS THE FIRST TIME.
You should reinstall the propellers
ONLY AFTER ENSURING THE FLIGHT CONTROLS ARE OPERATING CORRECTLY!
CALIBRATInG ThE GYRoS AnD InITIALIzInG ThE FLIGhT ConTRoLLER (ALL VERSIonS)
1) Pull the throttle control stick all the way back, verify that the Flight Mode Dial
(or the switch on your transmitter) is in the Beginner Flight Mode position,
then turn the transmitter ON.
Your Batfly 250 FPV Quad Racer is now ready for flight. Follow the steps in this section to calibrate the gyros and
initialize the Flight Controller, then arm the motors and fly your Quad Racer using the Beginner Flight Mode.
We strongly recommend flying your Quad Racer in the Beginner Flight Mode for at least the first few flights
before attempting to use any other Flight Mode. This will allow you to become familiar with the Quad Racer’s
flight characteristics.
Remember, if you’re using your own transmitter and receiver, you can assign Flight Modes
to the switch or dial on your transmitter you’ve designated to use for remote Flight Mode Switching.
For more
information, see the Using Flight Modes section on page 16.
If you have the Kit or Receiver-Ready versions and you’re using your own transmitter and receiver and you are
unable to arm the motors or if the flight controls do not operate as expected, the Flight Controller may not be
getting a low throttle signal or the flight controls are reversed. You can use the OpenFlight CC3D Flight Controller
software Configuration > Input menu to check your transmitter control stick output and make adjustments as necessary.
For more information, see the Using the OpenFlight CC3D Flight Controller Software section on pages 20 and 21.

2) Place the Quad Racer right-side up on a flat, level surface, then plug your
LiPo battery into the Power Connector. The Condition LED will flash Blue
rapidly while a series of audible tones sound.
Do not move the Quad Racer
during this time!
When the Flight Controller is initialized, the Condition LED
will flash Blue slowly.
If after 10 seconds, the Condition LED is still flashing rapidly or not
flashing at all, unplug your LiPo battery and restart the calibration
process again, making sure the Quad Racer is on a flat, level surface.
