Basic Quadcopter Tutorial - Chapter 4 - Power System 2 Video Lecture -

okay so back to the frame we're going to
mount the motors on now and I've already
got the propeller and the mounting plate
on the motor and I've got some screws in
here and this melts directly in to the
holes that I've drill and drill in the
frame now this is just something I add
on here it's just a plastic round lens
once again from the surplus store it
would be better if it was metal but I
wanted to just go ahead and provide a
little rigidity this way on the motor so
I've got two screws that hold it on and
then I've got the plate that just adds a
little agility now it's plastic I know
it's not real strong but it'll hopefully
help a little bit so I'm going to go
ahead and put these on
okay those are my four motors now one
thing I didn't mention was that when I
put these on this is actually the front
and so I've put my propellers on in the
right direction I'll show you where that
is in the manual but in the manual it
gives all the different configurations
in the directions of the propellers in
my on + configuration quad I need the
front and back propeller to be clockwise
that's the front and back and then I
need the right and left to be
counterclockwise and that's how a quad
works right we're going to use counter
rotating propellers in order to
counteract the force the torque created
by the motors it's a helicopter has a
tail rotor to prevent the unwanted yaw
right so we use counter rotating
propellers front back right and left to
counteract that that force so okay
there's my motors now I need my speed
controllers I have no idea what
direction these motors are going to spin
when I turn them on better just go ahead
and count them up and we'll figure that
out when we turn them on and we can
switch these barrel connectors that's
why we use barrel connectors and get the
right direction
okay I've got my four speed controllers
they're kind of flopping around here
that's no good I need to add some tie
wraps so tie wraps are really useful
again you're going to need some wire
cutters to be able to cut off the ends
but I'm going to go ahead and mount
these what's not them on the bottom
enter my quad over mounting them face
down only because they're a bit flatter
on the label side not too hard just
enough to hold them on there okay now
this is when we mount our wire harness
I've got a bunch of different wires here
these are all going to go on the other
side so I'm going to put them down here
get them out of the way these are the
wires I need and they're going to attach
to my wire harness all right no that's a
little messy and probably hard to look
at but the idea is I've got a connection
to each one of my es CS and that looks
good okay now I've got an added
component on here because I need to
mount the battery on the bottom I've
made this a little wooden plate and this
is going to mount on top of my wire
harness keeps things a little prettier
and will give me a nice platform to
mount my battery on
these are just nylon screws and I've got
an aluminum standoff in a plastic nut
now for this I used plastic simply
because I wanted a nice round soft head
on this side I didn't want the battery
to be compressed against like a hard
socket cap you've got to be very careful
with these lipos in terms of denting
them that's when the damage happens
there
that's my battery platform now I'm going
to add this strap and that will hold my
battery on for me and then that gives me
my loop for my battery and I've got my
wire harness here off to the side now
I've got a few few extra things here one
is I've got a few wires I'm going to
take this is the power for the hoverfly
Pro I'm going to put that through my
pass hole pass-through hole here now
I've got my power and then the other is
this alarm I want to be able to hear
that from the ground so I'm just going
to go ahead and put it right here one of
the arms okay
so that's the bottom of the quad and now
I'm ready for the hoverfly Pro now on
this craft this is the front then you
see on the board where it says front I
know the writing's upside down but that
white line should be facing forward so
the white line is and this is the
forward direction so I've got the front
here notice I've got those vibration
grommets
I'm going to go ahead and tighten these
nuts down on top
am I getting a wrench now I'm going to
hand tighten these I'm going to hand
tighten them because the vibration
grommets don't work if you squish them
between two nuts
it should just begin to mush down the
tops of the vibration grommet and that's
just enough just holding the board on
there so it doesn't flop around and
that's really nice it's not flopping
around so that's great I'm gonna since
I'm here I'm going to go ahead and
connect my power this is the power
connection from the battery harness I
can connect it as long as I've got power
in the middle and ground on one of the
sides it doesn't matter which way I
connect it here
ground is on both sides I can flip it
over if I want doesn't matter now that's
kind of messy so I'm going to I'm going
to come under here it's a little nicer
okay that's that now I need to connect
all of these wires
these are to my es CS and to do that I
want to check them I want to check the
manual
