250 FPV QUAD RACER USER'S GUIDE
Do not attempt to fly the 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. Check the propellers prior to each flight. If a propeller appears damaged in any way, it
should be replaced.
Be very careful not to cut yourself when you remove the propellers to replace them.

• The Quad Racer should never be flown in rain, sand, mud, snow or dirt. The Quad Racer is manufactured with
delicate components that must be kept dry and free of debris to ensure the best flight performance. Exposure to
moisture or excessive heat can result in damage that will not be covered under warranty.
• Just because the Quad Racer is powered by electric motors doesn’t mean that you shouldn’t exercise caution
when flying and operating it. The Quad Racer can be very dangerous and cause bodily injury if you do not fly it in
a safe manner or do not pay close attention while flying it. You alone are responsible for its actions during flight.
• The Quad Racer features three different Flight Modes - Beginner, Normal and Sport. We strongly suggest that when
you first begin flying the Quad Racer that you use the Beginner Flight Mode and perform only basic maneuvers until
you are more familiar with its flight characteristics. In addition, we don’t recommend using the FPV system until
after you’ve flown the Quad Racer a couple of times. This will allow you to learn the steps required for flight and
allow you to become familiar with the Quad Racer’s flight characteristics before using this feature.
• Always unplug your LiPo battery from the Quad Racer and from the FPV Receiver Monitor (if applicable) after use.
• Always fly the Quad Racer in a suitably large area free of obstructions. Remember, the Quad Racer is very fast
and reacts to control inputs very quickly, so you must always be paying careful attention when flying it.

• The radio system operates on the 2.4GHz frequency band. The 2.4GHz connection is determined by the transmitter
and receiver pair. Unlike ordinary crystal-based systems, the Quad Racer can be flown without frequency control.
• Always turn the transmitter ON before plugging your LiPo battery into the Quad Racer and always unplug your
LiPo battery from the Quad Racer before turning the transmitter OFF.
• Because the Quad Racer is operated by radio control, it’s important to make sure you are always using fresh
transmitter batteries. Never allow the transmitter batteries to run low or you might experience loss of control.
• Do not expose the transmitter to moisture or excessive heat and never attempt to disassemble or modify any of
the radio control system components.
• Do not cover the transmitter antenna (top of transmitter) in any way during use! Doing so can block the RF signal,
resulting in loss of control of your Quad Racer.
• During use, hold the transmitter so that its orientated as close to vertical as possible at all times. This provides
the best RF signal between the transmitter and the receiver inside the Quad Racer. Try not to ‘follow’ the Quad
Racer with the transmitter, as this can result in a weakened RF signal.
• Prior to each flight you should double-check that the flight controls are functioning normally (motors turn ON and
react to control inputs). Prior to the first flight of the day or after a bad crash, check the controls from approximately
30 paces away from the Quad Racer, to ensure the radio control system is functioning properly.
• The receiver antenna wire consists of a coaxial cable (black portion) and a reception wire (silver portion). The
coaxial cable (black portion) can be bent into gentle curves; however, do not bend the coaxial cable acutely, or
repeatedly bend it, or the antenna core can be damaged. Do not bend the reception wire. Reception performance
decreases if the reception wire is bent.
• The receiver antenna wire is delicate, therefore, handle it with care. Do not pull on the receiver antenna wire with
force. Do not cut or extend the receiver antenna wire.
• If the transmitter becomes soiled, it can be cleaned using a damp cloth. Do not use any solvents to clean it.

These warnings and safety notes are important and must be followed closely. Please abide by this information and
follow the instructions in this User’s Guide to ensure maximum safety. It’s important that you fully understand not only
how to operate your Batfly 250 FPV Quad Racer, but also to fully understand the responsibility you have for its proper
use - both for your safety and the safety of others.
PRoPELLER SAFETY (ALL VERSIonS)
Your Batfly 250 FPV Quad Racer’s propellers are thin and very sharp. Although they are somewhat flexible to prevent
damage during minor mishaps, they can still be very dangerous.
WARNING:
Be careful! Do not allow your fingers, hands or other body parts to come into contact with the spinning
propeller blades or serious injury will result!
