BATFLY
250 FPV QUAD RACER USER'S GUIDE
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.
As a safety feature, your Batfly 250 FPV Quad Racer features self-locking spinner nuts. The spinner nuts
installed on the clockwise rotation motors are reverse thread.
InSTALLInG ThE PRoPELLERS (ALL VERSIonS)
1) Working with one motor at a time, unscrew the spinner nut from the
motor shaft, then install the propeller (either ‘5030’ or ‘5030R’) depending
on the motor direction of rotation.
The ‘5030’ and ‘5030R’ text should face
UP when the propellers are installed.
2) Thread the spinner nut onto the motor shaft and tighten it using the carbon
fiber wrench included.
Be careful not to cut yourself on the edges of the
propellers when you install them!

3) Mount your receiver to the top plate, using a piece of double-side foam
tape (not included). Alternately, if your receiver is small enough and features
horizontal Channel Port Pins, it can be mounted on top of the Flight Controller.
Refer to your radio system or receiver User’s Guide for information
about routing your receiver antenna wire (or wires). Be sure that you
secure the antenna wire (or wires) securely so they can’t come loose and
get caught up in the propellers.
Transmitter Setup:
The transmitter you choose should be a 5-channel or more computer radio. Create a new
standard aircraft model (normal wing, normal tail, one aileron servo, etc.) and ensure all
programming values are set to their default values to start. Trim and sub-trim should be
zero, all mixing controls should be turned off, throttle hold should be disabled, all channel
high and low EPAs should be set to -100% to +100% (or both 100%, depending on transmitter brand) and throttle
servo reversing values should be set as shown in the table.
Follow the information in this section to install the transmitter batteries (Ready-to-Fly version) and fully charge and
install your LiPo flight battery.
InSTALLInG ThE TRAnSmITTER BATTERIES (READY-To-FLY VERSIon)
1) Remove the battery cover and pull out the battery holder from the back of
the transmitter.
2) Install 8 new ‘AA’ alkaline batteries into the battery holder, double-checking
to make sure that the polarity is correct, then reinstall the battery holder
and the battery cover.
Do not mix old and new batteries and do not mix
battery types.
PRO TIP:
We don’t recommend setting up or using the FPV system yet. Information about using the FPV system,
switching Flight Modes and using the LED light system will be covered later in this User’s Guide. It’s important that
you first learn to set up and fly your new Quad Racer without worrying about using these more advanced features.
IMPORTANT:
Prior to your first flight, you should use the OpenPilot GCS CC3D Flight Controller software
Configuration > Input menu to check your transmitter’s control stick output to ensure the controls are working
properly (you many need to reverse flight controls) and to 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 the OpenFlight
CC3D Flight Controller Software section on pages 20 and 21, and the Using Flight Modes section on page 16.
