FLYInG TIPS (ALL VERSIonS)
Your Batfly 250 FPV Quad Racer is a powerful, high-performance racing drone and you must use caution at
all times when flying it. In this section we’ve provided some basic flying tips to help you get started.
• If at any time during flight you begin to lose control of the Quad Racer and are unable to regain control before
crashing into something or someone, pull the left control stick (throttle) all the way back to shut the Quad Racer
down and allow it to crash land on its own.
• Always fly the Quad Racer in a suitably large area free of obstructions. Flying in strong or gusty winds can make
the Quad Racer more difficult to control and should not be attempted until you are a proficient flier.
• When moving the control sticks, use only small, smooth control inputs. Using large, abrupt control inputs can
cause you to over-control, making the Quad Racer more difficult to fly and possibly result in a crash.
• In general the Quad Racer’s controls do not need to be re-corrected as helicopters do, so control inputs should
be given and the control sticks returned to center before the next control input.
• When the front of the Quad Racer is facing toward you, the right and left roll and yaw controls will seem reversed.
Imagining yourself sitting in the “cockpit” will help you get used to this.
• Always try to keep the Quad Racer at least 3 feet off the ground during flight to keep it out of the ground effect.
Flying within the ground effect (less than 3 feet off the ground) will make the Quad Racer more difficult to fly.
FLYInG BASICS (ALL VERSIonS)
When learning to fly, we suggest always trying to keep the Quad Racer about 3 feet off the ground and in a relatively
small flying area. To be successful when learning, make small control inputs. Over-controlling is a mistake all new
pilots make. Never move the control sticks more than halfway except the throttle, and only when necessary.
You should have completed the following steps prior to flight:
• Fully charge and install your LiPo flight battery.
• Pull the left control stick all the way back and turn the transmitter ON. Verify that the Flight Mode Dial (or the
switch on your transmitter) is in the Beginner Flight Mode position.
• Plug your LiPo battery in and allow the gyros to calibrate and the Flight Controller to initialize. This takes
approximately 10 seconds. The Condition LED will flash Blue slowly.
• Arm the motors.
Remember, you must re-arm the motors if you don’t advance the throttle within 30 seconds.
1) With the front of the Quad Racer facing away from you, slowly push the throttle forward until the propellers begin
to spin. Continue to push the throttle forward to increase the speed of the motors and take off.
2) Gently move the right control stick as required in small increments to keep the Quad Racer hovering in the same
general area about 3 feet off the ground. At the same time you will need to increase or decrease the throttle to
keep the Quad Racer hovering a consistent distance off the ground.
As you take off, it’s normal for the Quad Racer to drift backward until you climb higher out of the ground
effect. To counter-act this, gently push the right control stick forward.
3) While making small adjustments to the throttle to keep the Quad Racer hovering in the same general area about 3
feet off the ground, gently move the right control stick to the right and left and see how the Quad Racer banks and
moves to the right and left, then slowly move the right control stick forward and backward and see how the
Quad Racer banks and moves forward and backward. Remember, make gentle, small control inputs. Now gently
move the left control stick to the right and left and see how the Quad Racer spins around its vertical axis right and left.
4) Repeat moving the right and left control sticks slowly to the left and right, and forward and backward to get used
to how the Quad Racer moves, all while at the same time making small adjustments to the throttle to keep the
Quad Racer hovering about 3 feet off the ground.
5) Now try placing the Quad Racer in a stable hover and release the control sticks. The Quad Racer should stay in
the same general position on its own.
If the Quad Racer is continually moving one direction or the other when the control sticks are centered, and
it’s not caused by a constant cross-wind, the Quad Racer may require flight trimming. For more information,
see the Flight Trimming section on the next page.
DO NOT ATTEMPT TO FLY YOUR BATFLY 250 FPV QUAD RACER USING THE NORMAL OR SPORT FLIGHT
MODES UNTIL YOU’RE ACCUSTOMED TO FLYING IT USING THE BEGINNER FLIGHT MODE!
