Basic Quadcopter Tutorial - Chapter 8 - Motor Directions Video Lecture - Drones for Beginners: How to make Arduino Drones - Electronics and Communication Engineering (ECE)

okay so before we go fly we need to
check the rotation direction of all the
propellers so I've got the quad facing
away from us so this is front back right
and left the way it would be when you
first start flying it before we turn
this on now we need to check and make
sure we've got all our settings and our
transmitter correct so I'm going to go
into my transmitter we're using a
spectrum I've got an acro lure airplane
model setup brand new model I've
adjusted some things in here already but
you'll see what those are I go into my
servo setup I want to check the travel
adjust on everything so I've got
throttle aileron those are all 100%
elevator
that's right rudder and then gear gear
is the most important for this in terms
of the setup everything else should be
pretty close to what you need to fly the
the gear is actually the gain the
primary gain of the crash so if I move
this down to let's say 50 that's a
pretty good starting gain I don't know
how this is going to behave yet so 50
percent is what the hover fly pro will
use is the primary gain for everything
now you notice there's two settings here
and that's if you switch the gear switch
and that's to enable auto level this
will be the gain when I enable the
switch that is used in in Auto level but
we're not going to go through that in
this video we're just doing basic flying
today so this whichever position let's
say this is the zero position off that's
the position we're going to use for our
primary gain and I've got that set to
50% so okay everything's set up
correctly now I can go back and I'm
ready to turn on the the quad for the
first time here so I'm going to plug in
the battery
and then you're going to hear a whole
bunch of noises those are the ESC
starting out you're going to want to
watch the LED on your board and
hopefully you can see it in this video
it's blinking green right now okay it's
waiting for us to do something so if I
take my transmitter and I raise the
throttle up nothing's going to happen
okay I need to arm it so now I'm it's
ready to be armed so I go left and then
right I should get one beep and then two
beeps you notice that the LED blinks red
and then it stays red and now it's green
green means it's armed let's go through
that again I'm going to disarm it this
time I'm going to go left and then right
it's now disarmed I've got a blinking
green light right now if I raise the
throttle nothing happens okay I'm going
to arm it it's now armed or its army
when I get my solid green light I'm good
to go now when it's going through that
arming process I'm going to disarm it
again
when it's going through the arming
process and I've got that solid red
light if I move it around it's gonna
blink purple and then it goes back to
blinking green that means that the
calibration it does when it starts up
failed so it's going to go back to ready
to be armed mode and I give it a
left-right
I don't move at this time and I've got a
solid green now I'm ready to increase
the throttle now I want to do this just
a tiny bit what I'm looking for is
rotations let's start with the front
propeller the front propeller should be
rotating clockwise and it is the back
propeller should be rotating clockwise
and it's not so I'm going to disarm take
two of these connectors the bullet
connectors these bullet connectors I'm
going to take two I'll attach them and
then reattach them in the opposite
configuration so I switch two of them
now I'm going to arm it again and I've
got clockwise direction now so I've got
clockwise clockwise now this has to be
going counterclockwise it's not and that
one needs to be going counterclockwise
and it's not so I got pretty unlucky
that's okay I'm going to go ahead and
switch two of these
armed it again and I've got
counterclockwise counterclockwise
clockwise and clockwise now at this
point if I wanted to see how it was
going to behave as I throttled up and I
mounted it to the bench if I hold it
here and try throttle up you can do that
but understand that the hoverfly Pro is
going to assume that it's flying and try
to start making adjustments to the
motors so if you hold it down don't be
surprised if it starts going like this
it's trying to control the flight
without being held down I mean that's
how the algorithm works so if you're
going to bench test that's okay but
understand that the motors aren't going
to behave in a linear fashion they're
going to be trying to make the platform
level and it's being held down so it's
confused so we're going to disarm it and
unplug and go out and fly we'll see how
this thing flies
