Hello,
everyone,
my name is Leo ，
from DCJ smart.
Today I continue to give you introduction
about how does a factory make agriculture drone. 
This is the third video.
Here you can see 10L water tank，
pump，
flow meter.
joint parts，pipe，
and  frame.
Now let me show you how to assemble them.
By the first,
But first，you can see the flight controller 
and PMU，
and antenna module.
See the arrow
on power distribution board
it aim to the front of drone.
And flight controller
also point that direction.
It's very important.
I will explain all this things in other video.
On the back of drone frame
you can see 4 thick wire，  for batteries.
Turn over this board.
Now we start to loosen these 4 fixed base.
Now，is water tank assembly.
We loosen these 4 fixed base.
My purpose is to help all the people
who want to up level their agriculture work，
or help the the people who want to establish 
a new business and offer the service 
to local farmers，
or help the people to build up 
a workshop to sell agriculture drones and maintain them.
After all,
we need to protect farmers from toxic pesticides in a very efficient way.
If you start from Zero，

4 thick wire for batteries.
And you can see their water tank.
