We're gonna do today a variety drone.
When you hear drone, you'll be thinking like the one flying in sky right.
But today we're gonna make one for the road.
We can also call it as a backpack.
You need to know how to make this right?
Before going to the workshop, all the equipment to make this
are sponsored by Crosswinds RC YouTube channel.
Channel is run by Arun bro.
When saying about the channel,
they teach us how to make drone and planes.
And also making some experiments in those.
So if you visit that channel,
Crosswinds RC, you can learn
how to make drone and planes.
The channel link is provided in the description.
Let's go to the workshop!
Okay friends, let's start our work.
First of all, we're setting up
a frame for backpack.
We're making connections with the help of PVC pipes.
We've connected couple of T-joints and
we've attached PVC pipes on its end.
In that again, we're connecting couple more T-joints.
Likewise, we've done one pair.
In the similar way, we need two pairs.
Second pair which is already done is here.
Let's see how to make a frame now.
We can set couple more PVC pipes between these frames.
Previously we made a drone and
we made in a similar frame.
We're making it again for those who haven't seen that.
Okay, we're setting our frame.
On the T-joints, we can
attach small PVC pipes.
We've taken 3/4 inch PVC pipes.
 
On that T-joints, we can fix those.
Above that, we can
set the cap over it.
The caps which we're setting,
 
in that we will be setting the drone's motor.
We've taken 4 brushless motors and
leaves for that.
We can see how we're setting the motor
in the end cap.
We've taken 4 motors for 4 sides.
 
 
In the centre,
we've put an extra hole for the shaft to not hit while rotating.
We've added two more holes for the screws.
See the shaft shouldn't hit the cap,
so we pierced a hole and two holes on
the sides. In this, we can tighten with
screws.
When buying drone, it's better to purchase these screw.
We're tightening it with align key.
 
We've set on all 4 caps.
Now is to glue it on the frame.
I'm not showing you the glue scene as we forgot to shoot it.
So next is to,
attach the leaf into it.
We need to attach it in opposite direction.
Similarly we can set it on all 4 sides.
Normal drones provides thrust downwards but this
needs to provide upwards.
 
Let me show how to make the motor work.
This motor will have 3 leads.
This is ESC to connect to that lead.
We can call it as a controlling system.
It will extend a small signal to a big one.
We've taken a LiPo battery.
Also a controller to control servo motor.
No need of any flight controllers.
First we can take the ESC and
we can see 3 pins. We're connecting with banana clip.
When we buy motor,
the banana clip will be attached, we can just connect it to ESC.
Now we have to take the tester of servo motor.
We're connecting it.
It will have "+", "-", "S".
We can carefully connect it by looking the wires.
Finally we're going to
connect the battery.
When connecting the battery,
black should be connected with black and red to red.
Positive to Positive and Negative to Negative.
If we interchange and connect, our ESC will burn.
We can get an indication while connecting.
When we twist the knob, we can see the motor rotating.
If we increase, speed will increase
or can decrease as well.
That's why we are using this controller.
 
Now we can connect all 4 ESCs in 4 motors.
I showed this first itself in order to you not
getting confused while doing altogether.
On all 4 sides, we can connect with ESCs.
 
As we did eariler, ESC is connected
in banana clip lead.
Now to consolidate all wires from ESC,
we're taking a power distribution board.
So that the supply given from battery should
reach all 4 motors.
It will have positive and negative indicators, we can
connect it accordingly.
In such a way, the leads from ESC
is connected to the box.
So we can see that
only power wires from ESC are connected.
Now we've signal wires.
That we need to connect altogether
and then give to servo controller.
So we can take the servo controller,
here we have soldered 4 extra leads.
We've soldered it in parallel.
We can connect all these clips.
 
In our servo controller,
we can control all 4 motors.
All 4 leads are connected to it.
When we turn the servo controller, the motor will start to work.
Finally we can provide the supply.
We've taken 2 batteries and
connected each other.
We can place the battery here.
Tighten it with insulation tape so that it won't come off easily.
When we kept battery, underneath it we already
kept double-sided tape.
Anyway for safety, we're tightening it again.
No need to tighten more, we need to charge again.
 
When we connect the battery clip to this,
our circuit will close and we've received indication from motor.
We can test it.
Our motor is rotating
with good power.
Can feel nice air flow upwards.
 
The frame work is complete.
I'll show the power of it now.
Just look at this tree.
The leaves are moving away.
 
We're beginning the test now.
We're performing road test.
We've a skating board for it.
We're gonna start now, not sure what will happen.
We're starting now.
 
 
This is the end of the video.
I'll let you know the details of this backpack more.
This one motor can produce
700g thrust.
Means it will push 700g from our back.
That's for one motor, similarly we've 4 motors.
4x700 how much?
2800?
2.8 Kg thrust.
That much thrust is generated.
This drone can be run for
20 minutes continuously.
Also it's a
different experience.
Rather than going in skateboard simply,
we're getting more excitement while going with this.
The difference in backpack is
the propellers are placed in opposite direction unlike normal drones.
Drones provide thrust
downwards and is lifted.
But here we've turned the leaves, so that thrust is provided
backwards.
 
If anyone of you, especially kids,
you should follow safety precautions before attempting this.
These blades rotate at high RPM.
So safety is important. And if you're riding in road, use helmet.
There might be accidents if vehicles are going in that road.
Use it wisely with safety precautions.Hope you all liked today's video
