1.5 Autopilot
Solo uses a Pixhawk 2 autopilot running ArduPilot Copter software. ArduPilot is open-source flight control based on
the MAVlink communication protocol. Pixhawk 2 runs an ARM Cortex-M4 STM32F427 processor with 2 MB of flash
memory and 256 KB of RAM. Combined with an array of CAN, I2C, SPI, PWM, and UART interfaces, Pixhawk 2
uses a suite of onboard sensors to calculate Solo’s orientation and motion in flight. This data is input into ArduPilot’s
inertial navigation and position-estimation algorithms and combined with control inputs to send commands to Solo’s
propulsion system.
1.6 Propulsion
Solo uses four brushless 880 Kvmotors and four self-tightening propellers for propulsion. For control and
aerodynamic efficiency, two motors spin clockwise and two motors spin counterclockwise. Navigation in the air is
achieved by mixing propulsion of the four motors to actuate flight control along the roll, pitch, and yaw axes.
Each of the four motors is numbered by the marking on the arm. These numbers correspond to the autopilot
calculations for these commands and are used for indicating motor replacement procedures. Each motor is
controlled by an ESC (Electronic Speed Controller) that regulates the rotation of the motors to achieve the speed
commanded by the autopilot.

pilot skill, so the actual flight time may vary.) As a lithium polymer battery, the Solo Smart Battery requires specific
handling practices to ensure safe operation and prevent accidents. For more information about battery safety, see
Section 4.10, Flight Battery, on page 28.
2.3.1 Charging
The level of the battery charge is indicated by the lights below the power button. Press the power button once to
display the current power level. The Solo Smart Battery ships with approximately 50% charge, so charge fully before
your first flight for maximum flight time.
Remove the battery from Solo before charging by holding the release button and sliding the battery towards the
back of Solo. Charge the battery using the designated Solo charger only; using a different charger can damage the
battery or cause a fire.
To charge the battery, connect the Solo charger to the battery and a wall outlet. While charging, the indicator lights
pulse at the current level. An additional indicator on the battery charger turns from red to green when
the battery is fully charged. The battery takes approximately 1.5 hours to charge to 100%.
The optimal storage charge for the Solo Smart Battery is 50%. Storing the Solo Smart Battery at an excessively
depleted charge (7 percent and under) for an extended period might result in shorter battery life or permanent
damage to the battery.
