mAInTEnAnCE
In general, your Batfly 250 FPV Quad Racer doesn’t require much in the way of maintenance. Routine maintenance
should be performed on a regular basis. In addition, there may come a time when you need to replace the propellers or
bind the transmitter and receiver. This section covers these more common maintenance items you might encounter.
• Before each flight check that the propellers are free of any damage (e.g., nicks, cracks, etc.)
• Periodically check that all fasteners are accounted for and tight. This includes the motor mounting screws, nose
cone and body fairing screws, and all the screws that secure the top and bottom plates together.
• On a weekly basis, apply a drop or two of ball bearing oil to the motor bearings to keep the motors running
smoothly and efficiently. We recommend using Parma Bearing Oil (P/N 943321).
• Periodically clean the outside of the Quad Racer and the transmitter using a damp cloth to keep them free of
dirt and debris. Use a cleaning cloth designed for use with smart phones and tablets to clean the FPV Receiver
Monitor screen.
• Periodically check your LiPo flight battery each time you charge it for any signs of damage or swelling.

BInDInG ThE TRAnSmITTER AnD RECEIVER (READY-To-FLY VERSIon)
The transmitter and receiver have been paired at the factory and are ready for use. Follow the procedures in this
section if you should ever need to re-bind the transmitter and receiver. For example, if you needed to replace the
receiver as a result of a crash or if the transmitter requires replacement.
REPLACInG ThE PRoPELLERS (ALL VERSIonS)
Do not attempt to fly your Batfly 250 FPV Quad Racer if one or more of the propellers are damaged. Flying with
damaged propellers is not safe and can make the Quad Racer fly uncontrollably or cause bad vibrations that
can damage your Quad Racer.
1) To remove the propellers, carefully hold the propeller in one hand (be
careful not to cut yourself on the sharp blade edge) and use the carbon
fiber wrench included to loosen and remove the spinner nut.
Remember,
the CW rotation motors using reverse thread spinner nuts.
2) Remove the damaged propeller, then reinstall the replacement propeller,
making sure that you install the correct one (either ‘5030’ or ‘5030R’)
depending on the motor direction of rotation.
Use the top view photo on page 8 to determine what motor to install each propeller on, either clockwise
rotation (‘5030R’) or counter-clockwise rotation (‘5030’). The names ‘5030’ and ‘5030R’ are molded into the
top of each propeller to differentiate them. The text should face UP when the propellers are installed.
WARNING:
Make sure to install the replacement propellers in the correct configuration or the quadcopter won’t fly.
oPEnPILoT GCS CC3D FLIGhT ConTRoLLER SoFTwARE
The Batfly 250 FPV Quad Racer features a CC3D Digital Flight Controller that is programmed from the factory and
is ready for use; however, some programming changes may be required for proper use with your transmitter if you
have the Kit or Receiver-Ready version. The OpenPilot GCS CC3D Flight Controller software allows you to connect
your Batfly 250 FPV Quad Racer to your PC or laptop and make programming changes and parameter adjustments
to suit your specific setup.
For example, you are able to program the Flight Controller to work with your S.Bus or DSMX or DSM2 receiver, check
control stick outputs to ensure the flight controls are operating correctly, assign Flight Modes to the switch or dial you
want to use to remotely change Flight Modes, adjust Motor Arming Timeout settings, update the firmware and more.
1) Turn the transmitter ON, then plug your LiPo flight battery in and allow
the gyros to calibrate and the Flight Controller to initialize. The Receiver
Condition LED will flash slowly Green.
2) Place the transmitter within 2 feet of the receiver, then press and release
the Receiver Bind Button. The Receiver Condition LED will turn solid Green,
indicating the binding process is complete.
