D. Please ensure that the motors are connected in the correct ports: M5,
M6, M7, M8.

E. Perform motor test using “Pluto Controller”.

1. Go to Menu > Drone Settings > Motor test

2. Tap on “Spin all”`

F. Perform accelerometer calibration.

3. Verify if all propellers are rotating. If not, please verify step D.

1. This calibration accounts for misalignment of the flight controller and
frame.

14

2019 Drona Aviation

TIP: It's a good practice to perform Magnetometer calibration when:
a. Flying at new location

b. Replaced the motors

Note: During control, the flight controller assumes that it is perfectly

aligned to the ground. This results in drifts. To account for misalignment,

we need to calibrate the accelerometer.

G. Perform Magnetometer calibration

1. This calibration accounts for stray magnetic fields. This is essential to
achieve good yaw stability.

2. In the app, go to: Menu > Drone Settings > Mag. Calibration

2. Place Pluto1.2 on a perfectly level surface.

3. In the app, go to: Menu > Drone Settings > Acc. Calibration

4. This will reduce the drift, but not eliminate it completely. For
eliminating the drift you will have to trim the drone (please refer to
section: Trim).

Without proper magnetometer calibration, the yaw performance of the
drone is severely aected.

CAUTION

recalibrate. A few steps could have been missed out during calibration.

NOTE: If you are a beginner in flying drone, we recommend you to switch

to “Tilt mode”. Go to Menu > Control Settings > Tilt mode

Step 7: Arming the Drone

The ARM switch controls power to the motors. It can be thought of as a
safety switch. If during anypoint you want to shut the motors, you can use
the ARM switch to do so.

Disarming the drone will stop all motors immediately. You can disarm by
clicking on the disarm button.

Note: If you are new to drones, you will crash a number of times before you
learn how to fly. You don’t need to worry about the crash as the drone is

crash resistant.

Step 8: Fly it!

A. Place the drone with its front pointing away from you.

B. Click the ARM button.

C. Make sure you have a lot of open space.

D. Click on the Take-off button. PlutoX should take off to a height of
about 3 feet.

E. Try to control only the roll and pitch of the drone. This significantly
makes the flying task easy.

E. To land drone, press the Land button.

Trim is a feature used to ensure very low drifts in your Pluto1.2. You
might have observed that, when you take-off using the take-off button, the
drone drifts in some direction. TRIM is used to ensure very low drifts in
the XY-Plane.

Please perform the following steps:

1. Make sure that your have performed acc calibration before starting
Trim.

2. Identify which direction is the drone naturally drifting towards.

3. Using Pluto Controller navigate to:
Menu > Drone Settings > Trim

4. Trim the Drone in units of 5 to see considerable change. The units of

Control Settings

Flight Modes

Pluto1.2 has various flight modes. Changing the flight mode will change
the way you control your drone.

Althold / Throttle mode
This controls how you controls the drone in the Z-axis.

Throttle mode: When you choose this mode, you control the amount of
power supplied to the motors. This essentially controls the acceleration of
the drone in the Z-axis. This mode can be hard for a beginner as you
would constantly need to provide input to maintain altitude.

Althold mode: When you choose this mode, you control the velocity of
the drone in the Z-axis. This is much easier to control. When the control
stick is in the center, the drone tries to maintain its altitude.

Headfree mode: This mode affects the way you control roll and pitch of
the drone. When this mode is Off, the pilot needs to constantly monitor,
the yaw of the drone. If the pilot loses orientation of the drone, it can be
quite challenging to control the drone.
When headfree mode is On, the pilot doesn’t need to worry about the
yaw angle of the drone, the drone manupalites the roll and pitch inputs
accounting for changed yaw. This mode is highly recommended for
beginners.

Joystick/Tilt mode

: This customises how you control the roll/pitch of the

drone.

Joystick mode

: In this mode, the roll/pitch of the drone is controlled by
on screen joystick. As touch screen lacks tactile feedback, it required
some getting used to.

Tilt mode

: In this mode, the roll/pitch of the drone is controlled by the

tilt of your phone. This mode is much easier to fly for beginners.

Control Modes

21

2019 Drona Aviation

Sensitivity refers to the level of response the drone gives to the controller
inputs. For higher sensitivity, even a small input would reflect a huge
difference and for lower sensitivity, large inputs would be required for
noticeable change. Adjust the sensitivity according to the Pilot’s style of
flying.

This setting helps you limit the drone’s maximum height. By default your
drone does not limit the height.

Sensitivity

Max Altitude

Note: We recommend the beginners to keep the sensitivity levels to Low.

1. This feature is still in beta, please use with care.

2. This feature only works in Althold mode.

CAUTION

FAQ

Q: Some motors are not rotating.

This could happen due to multiple reasons. Please check the following:
Make sure that motor is inserted in the default motor ports: M5 / M6
/ M7 / M8.
Check if the motor cable is damaged. If damaged, replace the motor.
Check if propeller is able to freely rotate on the motor shaft. If not, use
the proptool to create some gap between motor and hub of propeller.

Q: Drone is not taking off

Please check the following:
Ensure that your battery is fully charged.
Propellers are mounted as recommended. Check “assembly / disassem-
bly” section for more information.
Check if you are connected to your Pluto’s wifi.
After you ‘connect’ to Pluto1.2 using the app, ensure that you are
getting a solid green LED. If not, please use the “LED status” section
above to correct for any errors.

Q: Drone keeps drifting

The drone controls angles and not velocities. Some drift can be expect-
ed. In order to reduce this drift you can try the following:
Perform Accelerometer calibration on a flat surface.
Please follow the “Trim” section to reduce drift as low as possible.

Q: Altitude Hold performs erratically.

To maintain altitude, the drone uses a mems barometer. You can
expect the altitude to vary +/- 50cm. This is normal. If the drone is
very erratic in Z-axis, one possible cause is excessive vibration. Please
ensure the following:
Replace propeller if the propeller is damaged. Very little damage can
also cause excessive vibrations
Make sure that the PrimusX board is not in contact with plastic part but
only the dampers.

Q: Cannot see the wifi Hotspot.

Please try restarting the drone.

Q: Drone keeps rotating / yawing.

Make sure that the drone’s magnetic calibration is performed properly.
