notamment des astuces sur la réglementation drone
l’objet de cet article n’est pas de t’expliquer les démarches à suivre en détail pour le devenir mais comme beaucoup m’ont demandé pourquoi j’ai passé. une formation professionnelle de drone, je t’explique rapidement les étapes clés pour devenir pilote de drone professionnel :
“map, dnc, rc pro…??? c’est bien là le but de la formation, tu vas tout. connaître après ces 5 jours complets 😉”
je tiens encore à remercier patrice rosier et toute l’équipe de reflet du monde de drone oblivion
m’avoir ouvert les portes de leur centre de formation
ils ont été les seuls parmi tous les organismes de

distance eg 220mm
the following table shows you a rough conversion of what you should look for size wise
there’s a lot to consider here! if you get stuck or are unsure have a look at pilots whose flying style you like and find out what they are flying
many top pilots have build videos that explain the key points of their frames and why they choose to fly them
another great resource to use to help you decide on parts is rotor builds
the site shows off user created drones and includes details such has parts lists and build guides! it’s a great place to find inspiration
these are the powerhouses that give your quad the thrust to reach the insane speeds modern drones are reaching
there’s alot of brushless motor choices out there for mini quad, it’s hard to decide
when choosing motors, there are specs that comes with the motor provided by the manufacturer
you should be able to find detailed information about the weight, thrust, power, rpm etc
when building the drone take a closer look at this specs in a motor:
the first point is the size, a motor size is typically noted in a xxyy format with the first two digits referring to the stator diameter in mm and the second two being the height of the magnets
basically the larger these numbers are, the higher torque the motor is able to produce, think of it like engine size with the drawback of larger sizes being the weight
in terms of performance higher torque allows the motor to hit it’s target speed faster increasing the feel and response of the drone
this could be useful in the case of a heavier quad or when running heavy props
another factor to consider is kv, this stands for the motors velocity constant which means how many rpm per volt your motor can give for example a 2300kv motor at full throttle on 10v would be spinning at 23000rpm
selecting the kv value is like selecting a gear in a manual transmission
going low gives you more torque but less top speed and going higher will increase your top speed at the price of torque
generally speaking going higher requires either a big powerful motor or an incredibly light setup
a 3″ setup for example will have a much higher kv rating when compared to a 5″ design
the following table lists some possible options for you depending on your prop size:
when looking for a motor you should be able to find a specification table that gives you details on thrust with different props and amp draw which we will need to know later
generally with a mini quad you should be aiming for a 10-1 thrust to weight ratio
the following table is an example from an emax rs2205 red bottom motor which in early 2016 was a top performing 5″ motor
these days it has average performance compared with the competition but would be great for a first build
quadcopter brushless motor guide
a great resource for researching and comparing motors is miniquad test bench: which is run by ryan harrell
on the site ryan gives feedback on most modern motors and provides all the data for you to evaluate and draw up your own comparisons
if you are unsure if you have the right sized motor look at some of the props is spinning and see if it fits in with your expectations
these small components known as electronic speed controllers are what produces the three phase ac current needed to drive your motors
the flight controller sends a signal to the esc to let it know how fast it wants it to spin the motor at a given point in time
you will need one esc for each motor, you can either get four separate escs to mount them on the arms or get an all in one board that sits inside your frame if you have the room
the amp draw of your setup! remember those motor tables you were looking at? you’ll notice that there is an amp draw column
you will need your escs burst current to exceed this value or they could burst into flames up mid flight!
escs are reasonably intelligent and can run on different software
at the time of writing you should only really consider escs running blheli_s or kiss escs
the old blheli or simon k software is now outdated
the esc can talk to the flight controller through various protocols (think of them as languages)
the current standard protocol is dshot, if an esc does not support dshot 600 or greater it is not worth considering these days
the flight controller is the brain of your drone taking into account the angle of your drone and your control input it calculates how fast the motors should spin and sends the signals to the escs
flight controllers are normally built for certain software such
