This is a quick guide for those new to Multi-Rotor craft oering some basic safety and operational procedures...and are
recommended standard operating procedures for those piloting Droidworx or any multi-rotor craft.
Please read the instructions for the relevant Flight Control electronics before proceeding. Go to the web site of your ight control
system and make yourself well acquainted with the correct procedure for the electronics installation and software operation.
Caution: never connect and start the engines for the rst time with the propellers attached....and always balance your propellers;
unbalanced propellers can cause excessive vibration which may lead to material fatigue.
Note: check the orientation of the ight controller you are using (which way is front) and also the engine assignment conguration;
for instance which is engine 1,2,3 etc. and check also that your propellers, clockwise and counter clockwise, are also installed
correctly before your rst ight.
Before the rst ight hand test your craft – arm and calibrate your electronics, hold the craft with both hands by the landing gear
skids above your head with the front facing away from, and to the front of you, make sure you are well clear of obstructions and
other people. You may need the assistance of another person for this test. Raise the throttle to around 25% and gently move
the craft around the axis’ roll (tipping the craft left and right) and feel for a steady and smooth resistance to your movements, do
the same for pitch (tipping the craft forward and backward) and also yaw, rotating the craft clockwise and anti-clockwise whilst
keeping it horizontal. If the craft oers smooth resistance to your movements it will y correctly.
Your rst test ight should be in an open eld in low or zero wind. A sports eld (not currently in use) is a good option; choose a
site with short or mown grass. Do not takeo from dry dusty sites. Make sure any onlookers or spectators do not gather about
you…if so ask them to move away from you in a perimeter not less than 50m (150 feet) diameter around you.

Make sure that you have fully charged your transmitter and onboard battery packs. Make sure that the antenna of your Radio (TX)
is up and correctly positioned; make sure the receiver (RX) for your craft is well positioned within the craft and secured and that
the antenna is facing downward and to the back of your craft and not touching any part of the craft.
Place the craft on level ground and turn on your transmitter – check that you have the correct model selected on your TX.
Set the transmitter timer to about 80% of the known ight duration.
Connect the battery to your crafts FC inputs and wait for the engine controller beeps to stop.
Stand about 4m away from your craft and behind the craft with the craft facing directly away from you.
Check the 50m ight safety perimeter you have established, also checking behind you for children running in to see what you are
doing.
Survey the area; look for obstacles that you might not have seen previously, like power-lines and overhead wires.
Never y your craft near a controlled aerodrome or in controlled airspace.
Check the weather conditions, the wind speed and direction. Do not y in gusty strong wind at any time. Always try and y the
craft with the wind at your back so the craft will drift directly away from you.
Always keep your eyes on the craft when in ight – if people approach you inside your safety perimeter to talk to you or to ask
questions whilst you are ying the craft do not engage in the conversation and ask them to stand well clear of you until you have
landed.
Re-check your perimeter and raise the throttle slowly and check to see if the craft wants to tilt to one direction or another;
sometimes you may need to adjust the trim on your TX to get a level ight, however most times the craft will y perfectly rst
time if you have installed the electronics and the software has been set correctly—check with the Flight Control manufacturer for
standard or beginner settings for the craft.
Takeos are sometimes easier with a short burst of power to lift the craft o the ground.
Hold the craft in a controlled hover directly in front of you about 2-3m o the ground away from “ground eect” prop wash.
When you have mastered this hover position you can then move on to rolling the craft gently from side to side and forward and
backward. Make sure that you always stand behind the craft, this makes for easy orientation of the ight controls.
Repeat this exercise several times before you take the craft any higher.
Always y the craft well away from people and / or property. Always check for children nearby.

Thoroughly check the craft before every ight…
Pre-Flight Safety Checke safe and secure and not loose.
Check to see if any wires have come o
Check for loose bolts on the assembly
Check that the battery’s are secure
Check the battery voltage, and if you have more than one battery, check your spares too
Check the propellers for marks and nicks
Check the propeller nuts or bolts, make sure they are tight
Check the engine mounts and the bolts and nuts for tightness
Check the Transmitter battery voltage; never y the craft with a low voltage reading on your transmitter
(check with the manufacturer of your equipment for minimum and maximum voltage readings).
Check that the transmitter antenna is not damaged.
Check that the craft receiver module is well connected and that the antenna’s are properly positioned.
Take a good look over the craft from all sides to make sure that nothing appears unusual or out of place.
Check your ight perimeter.
Check for power-lines and overhead obstacles.
Assess the weather conditions, wind direction and speed. An anemometer (hand held wind speed meter) is a good tool
to have, otherwise use some dry grass or a tissue, throwing in the air to gauge the wind direction. Do not y in gusty
and turbulent conditions.
Set your transmitter timer to 80% of the known battery duration.

d o ’ s a n d d o n t ’ s :
Never y in strong wind – the operational safe wind speed for these craft is about 10-15 KPH.
In the event of a crash or a hard landing, always check the craft for damage before taking o again. In this instance, you must also
check that you do not have dirt or grit in the engines; this can cause an engine or engines to overheat and fail in ight resulting in an
out of control craft and serious damage or injury to the craft , other people and their property.
Your launch eld should preferably be open and at with short grass. If it is necessary to take o in a eld which only has long grass,
manually atten a 1.5m diameter take o perimeter with your feet.
Always have a ight plan – visualize your ight path and check again for obstacles.
Never y the craft out of direct line of sight and always keep your eyes on the craft whilst it is in the air.
Never y the craft above 400 feet in height (the length of a football eld).
Never y near people – a 50m (150 ft) perimeter around and above people is a recommended minimum and operational law in most
countries.
Always set your transmitter timer before each ight to about 80% of the known ight duration for the battery pack’s you have
installed in the craft.
Never turn your transmitter o in ight.
First person view ights are against the law in some countries – check the relevant aviation safety authority in your country before
ying FPV. Always have a “spotter” with if you do y FPV.
Never let friends y your craft unless they are well schooled in the discipline.
Never y under the inuence of any substance or alcohol. Whilst there is a minimum blood alcohol level allowed for driving an
automobile in most countries, the law for pilots in command of ying craft around the globe is universal…there is a zero limit
tolerance.
Always turn your transmitter on before connecting the battery to the craft...and always disconnect the battery from the craft before
turning your transmitter o.
