In this lesson, we'll overview populating the component tray.
After completing this lesson,
you will be able to install the receiver in flight controller and install the ESCs.
Next, we're going to work on assembling the component tray.
Now in this case, the power distribution board is
already screwed in with these four screws.
What I want to focus on is how the rest of the components fit.
I'm going to get started by plugging in the flight controller as well
as the controller receiver.
So now, we can see where those wires go.
I do want to make note that the port on the side
for the micro USB is how we're going to program the controller.
Now this controller has already been programmed
but when we get to actually plugging it in,
we'll have to remove it because of obstructions through the EFCs.
So the flight controller is going to sit in this area and when we're completely done,
we're going to remove the double sided tape and we're
going to make sure that it stays in place.
There's a little bit of prelift from the side so it does hold it in place just fine,
but for actual flight,
we want to make sure that it's nice and firm.
We're going to use the features we created to hold the receiver.
In this case, I'm actually going to use an earplug plug.
So, I'm going to squish it down on the sides,
I'm going to press it in,
and because these will expand,
they'll allow it to hold that in place and we don't have to worry about using
adhesive tape or anything else to hold it place.
It's wire is going
to come out of this hole and we're going to zip tie it to the airframe at some point.
One of the biggest challenges with assembling or
designing your own quad copter is going to be cable management.
Now in this case, these cables can all be relatively short.
But I left them long just in case we decided to use a different controller.
But what we can do is we can pull the wires in this direction.
And we can sort of tuck them in here.
That way, they are out of the way.
Next, we're going to start to assemble the ESCs and I want to
make a note about plugging them in and where the wires need to go.
Since I have prewired everything,
I have them numbered so I know which one goes to one, two, three,
and four and the wire colors on
the motors themselves correspond to
the right colors on here so I know the direction is right.
When this gets assembled on the airframe we have
our micro CCD3 pointing forward and we have motor one,
two, three, and four going around clockwise direction.
So it's important when you start to assemble these that you
remember which motor is going to be going in which location,
so that way, the wires can exit in the right spot.
So motor number one is going to be in this orientation.
So I'm going to place the ESC inside of
the channel and I want to make sure that the wires exit in the right place.
So, these are going to be pulled around and these are going to be pulled around as well,
and we'll place it into that slot,
making sure that your power wires are out of the way.
So now, we can take the signal wire as well as the power and ground,
plug it into the power distribution board,
and the wires can come out and go to our motor.
So, let's carry on putting a few more in.
I'm going to reverse four,
so that it's wires to the motor come out on the back corner.
So that way, it's a good reminder for me where these need to go.
And again, your biggest challenge in this case is going to be cable management
because it's always going to be difficult to fit everything in to a small component tray.
So now, you can see we have got the ESC leads going out to the motor
which will be number four and the ones up front will be going out to number one.
So, I'm going to take this point to plug a few things in and get these cables
in the right place.
This will be time lapsed now.
5:26
Next, let's talk a bit about the connection from the ESC to the flight controller.
Now each of these has a black and a white wire.
The three pins on the flight controller correspond to ground at the bottom,
power in the middle, and signal on top.
So none of the ESCs get power from the flight controller with this wire,
they only get signal in ground.
So since this is number one,
it's going to connect to number one how it corresponds on the flight controller.
Since this is number four,
it's going to go to the fourth set of pins.
This leaves us two and three for the other ESCs.
6:47
Now, with both sets the wires,
just to make it easier to work on,
we're going to snip the zip ties,
so that way, we can rest on the battery's sides.
So now, inside here, we need to plug in the last two signal wires.
So it's very important that we take a look and make
sure we're getting them from the correct ESCs.
So, this one here is number two.
So again, the white wire is on top,
and the last one over here is for number four.
Again, this cable management is going to be a problem.
And as we look at this,
this is a great opportunity for a new revision to handle the cables a little bit better.
So, we're going to come through here
and plug into the third spot for motor number three.
So now, we have one,
two, three and four ESCs.
We've got the receiver plugged in.
We've got the connectors that are going to go out to our motor,
and we've also got the camera and we've got the antenna receiver on the back end.
So from our power distribution board,
we have this last connector here that we need to plug in.
This is going to power everything.
So it only has a ground and a power on it.
Remember the middle pin is power.
So we need to make sure that it's on the bottom
too and that the upper pin for signal is exposed.
This last one here is going to be the server for our camera.
8:45
As we take a look at this,
the camera connectors are going to be on the outside,
the server connector needs to come into the screw,
tuck it in wherever it can go,
and remember, powers in the middle,
brown is ground, in this case, an orange signal.
So the orange is going to be on the top end.
The rest are going to follow.
So now at this point,
everything is plugged in.
We have signal from the controller,
we have the ESCs plugged in,
we have believed that are going to come out to
our motors and now at this point we need to simply bolt it on.
