MD2 Dronekit

Start by studying the safety information on the next page. Propellers
can cause damage and must therefore be distributed at the end.
Paper propellers are used temporarily to test that the motors are
going in the right direction.

Construction plan:
There are four main areas, which should be done in this order:
assembly, electrical connections, programming and flying. !
You are welcome to delegate the four tasks to different students,
who are each given their own main responsibility, which they can
later roll on (especially the flight).!
Once the drone is built and the electrical connection is made, check
the following before getting the battery:!
Layout, page 8. Silver motor in the right place. Two different colors
of propeller protectors, one at the front and another at the rear.
(Color may vary).!
Wiring diagram, page 15. It is especially important not to switch
between + and - between ESC (speed controllers) and power
distribution boards, as well as not to change the battery measuring
cable and speaker cable.!
Charge the batteries. Put the battery in the
enclosed charging bag. All lights should be
green before charging is complete after 1-2
hours.!
Insert 4 AA batteries into the radio. We
recommend rechargeable batteries for the sake
of the environment.!
The drone flies for 11-13 minutes on one battery.!
Reset the drone's control card by selecting
“factory reset” which is located at the very
bottom of the menu.!
•When they have finished programming, you or students
(other than those who have programmed) should check the
following:!
•The paper propellers should rotate straight in accordance
with the layout, page 8.!
•Review receiver test, page 18. Check that the movements of
the connectors are correctly reflected on the screen. Throttle
= gas, left stick down = 0, up = about 100!
•Yaw (rudder) = side rotation, left stick to the right / left results
in “rudder left / right” +/- about 100!
•Pitch (elevator), right stick forwards or backwards, +/-
approx. 100!
•Roll (aileron), right stitch to the side, +/- approx. 100!
•Check that all wires and components are attached correctly
and that no wires or antenna can be cut by the propellers.!
•Once this has been checked, you can distribute the
propellers. It is important to distinguish between up and
down, as well as right- and left-rotating propellers. See page
9. Make students aware of the dangers associated with
propellers.!
Flight:
The pilot and the rest of the team take the drone to a suitable
flight area. Gym or other open space indoors is the safest and
is unregulated by FAA and aviation authorities. Avoid third
persons entering the flight area and especially smalle children
must be kept at a safe distance. Low ceiling height can also be
an advantage as you can not crash from a great height.!
Outdoors, large grass pitches are the best place to fly as it is
open, and the surface is soft and damages the drone less in the
event of a crash. Provide the required safety distance to
outsiders. Check local rules regarding flight outdoors.
Tools:
1.5mm Allen or Torx. Star puller medium size. Scissors if you
want to cut out paper propellers.!
To the teacher

PROPELL
BATTERI
ARMERING
When the drone is armed* and the propellers are
mounted.!
you must have at least 2 meters safety distance to
the nearest person.!
*Arming: The drone is activated and the propellers
can spin. Characteristics: Red light on control card,
it says "ARMED" in the display.!
The drone battery (LiPo), can develop heat and toxic
fumes if it is severely damaged. It the batteri suddenly
inflates or starts to extract smoke, get the battery outside
the premises, and away from people as quickly as
possible. !
Have a plan for this in advance.
Rule 1:
Rule 2:
3
Propeller hazard
The propellers rotate at up to 28,000 rpm. minute.
Show respect for the forces and damage potential of
the propellers when the drone has battery connected.!
Keep the required safety distance when the drone is
armed.
Aviation rules
When flying outdoors, make sure to follow local drone
rules. Keep a safe distance so as not to endanger other
people.
It is not recommended to fly this drone higher than the
roof of the nearest building and no more than 30
meters away from yourself. This will help you retain
control of the drone.

Assembly
As assembly manager, your job is to make sure that all the parts are assembled together in
the right way. Use the attached drawings and get a couple of free hands from your team
members.!
You are responsible for all assembly except connection of wires, which is left to a
knowledgeable electrician when your job is done.!
What you need to do:!
•Get the necessary tools: Medium-sized Phillips screwdriver, 1.5mm Allen key, scissors!
•Follow the construction instructions. You will receive parts from the component manager as
you need them. Bring helpers with you, then it might go faster.

Mounting the propeller
We recommend saving this part until everything else is mounted.
Always make sure that the battery is disconnected before mounting
the propeller!
Also, make sure that you have tested and adjusted the direction of
rotation so that they are correct.
Unscrew the bolts on top of the engine and place the propeller on the
screw.
Tighten the bolts again. They can be screwed with your fingers and
should not sit particularly hard. They tighten themselves during flight.
Silver motor head should be screwed the opposite way of black motor
head.

We have two types of propellers, right and left rotating. (Regardless of
color)
Right-rotating is marked R, eg 5030R. Install the propellers according
to the overview above.

Programming
As a programmer, you must make sure that the control card is configured with the
necessary parameters and calibrations that are necessary for the quadcopter to work.
Be careful so that the drone flies stably.
17

Oppstart
Turn on the radio transmitter.
Then connect the power by plugging in the drone battery in the yellow plug. The
control board then starts up and you should hear a beep in the buzzer.
• There should also be a beep every time you press a button.
• If the buzzer does not make a sound, tell the electrician to fix it.
• There may be error messages on the screen, which will disappear later.
• Check that the battery meter works. A full battery is about 12.6 volts. The
display should then say: “Battery: 12.6 volts”
ACC Calibration
We need to calibrate the accelerometer so that the control board knows
where the ground is.
Click “MENU” and “UP / DOWN” until you find this item. Follow the
instructions.
Setup radio receiver
This must be done together with the pilot.
Go to “Receiver Test”. Here it is important that both jacks on the
remote control correspond to the deflections on the screen. Each stick
represents two channels and is called Aileron (Roll), Elevator (Pitch),
Throttle and Rudder (Yaw). It is very important that the movement
detected on the screen is correct. For example, a right movement with
the right stick should result in the effect "Aileron: Right" on the screen.
Check that all four directions of flight are correctly registered by
the control card, both in cases of "left" and "right" as well as
"forward and" backward ".
The throttle should go from about 0 when it is down, to about 100
when it is at max. If this is reversed, you can use the reversal buttons:
Sticks vs screen
18
You should also make sure that the numbers are around 0 (+/-
5), when the sticks are in the neutral position, ie the throttle is in
the lower position, while the others bounce back to their starting
point. The trim buttons are used for this.

Battery alarm
To know when the battery is nearing the end, we must program the
voltage alarm. Go to Misc settings 1 -> Alarm 1/10 volts. Enter 105
(10.5 volts).
Our 3-cell battery will be fully charged at 12.6 volts and completely
empty at 9.9 volts.
Fullt: 12.6 Volt
Helt tomt: 9.9 Volt !

Self-level
Self-level means that the quadcopter returns to a horizontal position when
we release the plugs. Go to Mode settings -> Self-Level: Always
Motor Layout
It is important to let the control card know what kind of multirotor you have.
Navigate to “Load motor layout” and select quadrocopter X mode ”.
You will then get an overview of:
• Location of engines
• Directions of rotation
• Engine number
Check with the electrician if the controllers 1-4 are connected to the correct
output on the control board, according to the wiring diagram (page 14)
Now, together with the pilot, check the direction of
rotation of the engines, one by one.
• Install paper or paper propellers (page 24) on the
motors.
• Arm the drone (see page 23) and gently
accelerate until the engines spin.
• Check if the motors are going in the right
direction. See layout page 6
• If an engine does not spin directly in relation to
the engine layout, the direction must be reversed.
• You do this by switching any two plugs between
motor and regulator.
19

The next thing to do is called the throttle range and is done to calibrate the controllers so
that they interpret the control signals from the control board in the same way. Here you
must be two people. No propeller can be mounted at this stage.
Disconnect the battery on the drone.
Kalibrering av regulatorer
Start by turning on the remote control and set the throttle to max.
Person 1 holds down buttons 1 and 4 on the flight controller at the same
time and holds these until the procedure is completed. Person 2 then
connects the battery on the quadcopter. The screen should show
"Throttle pass trough". Wait about 4 seconds - a beep sounds.
As soon as this signal is complete, immediately lower the
throttles to zero. Wait for a new signal. You can now release
buttons 1 and 4. Restart the quadcopter by pulling out and
inserting the battery again (the radio transmitter is on all the
time).
Verify that all the motors spin up when arming. Propeller should still be off! Gently
accelerate with the throttle. At a certain point, all the motors should start spinning
almost as fast. It is an advantage that the quadcopter stands horizontally on this test.
