4.PutthequadcopterstationaryandCheckforthefollowing:
A:Gyroscopesandaccelerometers
Check the 3-axis gyroscope and 3-axis accelerometer
values. Pick up your quadcopter and move in
different directions to check if values are changing. If
yes, it's in normalworkingcondition
B:Barometer
Check if barometer values are changing slightly.
Under normal circumstances there should be little c

Compass data is veryimportantdata.Do makesure that
compass values arechanging when you pick up and
rotatetheQuadcopter360degrees.Ifthosevaluesdonotchange,thatmeanscompassisdamaged.Kindlycontactyour
localdealerfor further instructions.
Default values for Gyro Gain, Aux Gain, Alt Gain and Low voltage are as follow:
Gyro Gain = 18
Aux Gain = 6.80
Alt Gain = 12
Low Voltage = 11.1
In case you mess up the settings please remember to use above default settings as your starting point.
Gyro Gain is the 6 axis gyro gain setting
Aux Gain is the G Sensor gain setting
Alt Gain is the Altitude hold gain setting
Low Voltage Gain is the Low voltage alarm setting

SettinguptheTimeronRadio:
You can set countdown timers on your radio to assist you flyfor a setperiod
of time. For instance if you want to flyfor 15minutes, youcanset15 minutes
countdown timer on your radio. Once timer reaching to 0, Radio willgive
you audiblewarnings and you canstopflying(Returnto homeand

WheretoFly(FlightSafetyTips)
1. Make sure to find aclear open area to fly. The areashould not have magnetic interference. Do not useother devices
that causemagnetic interference like Mobilephones, othertransmissionequipment, speakers,cameraswith lots of noise
and interferenceetc. Some Buildings, bridges andorstadium areas have a lotof steel andmetalused in their
constructions,thisallcanaffecttransmission.
2. Do not flyin bad weather. Though FreeX uses waterproof motors and ESCs we still suggest not flying duringrain,
foggydaysorextremehumiddays.
3. FreeX can handle a decent amount of winds from 5mphto 15mphbut still we suggest notflying during verywindy
andgustydays.
4. Whenflying, keep awayfrom high powerlines, power poles,roadlamp posts, transmissiontowers,and high voltage
lines.Inadditionkeepclearfrompeople,waterandtreesandproperty.
5. Makesuretoflyin areawheretherearen'tanyWIFIdevices inuse,otherelectronicdevices,cellphone towers,high

Quadwillholditsposition.TrytofigureoutifQuadcopterisfacingawayforfacingtoyou,youcanuseChannel4(rudder)to
yaw and see if you can figure out quadcopter rear or nose. It willbe easier for you to flyit back if you re-establish

Normallyit is easier to find qudcopter rear, due to rear LEDs on the Quadcopter. In case you are too far, and can't
