Flight School
If you're new to flying, review the video tutorials in the Flight School area of the app before your first flight. Flight
School provides useful tips for learning to operate Solo safely and correctly.

Propellers
Spinning propellers can cause serious injury. Never touch moving
propellers or place any objects in the way of the propeller arcs while
Solo is powered.
To avoid hazardous contact with Solo's high-speed propellers, always power off Solo before handling Solo or
the propellers. When prompted to start motors before takeoff, always ensure that the propellers are clear of any
obstructions and at least 20 feet away from any people, animals, or property before activating. Do not touch moving
propellers or approach Solo while the propellers are spinning.
After landing or returning home, Solo automatically detects the landing and stops the motors. Do not approach Solo
until the propellers stop spinning, and always power off Solo before picking it up.
4.6
GPS
Solo requires an active GPS signal for flight. After powering on, Solo can take up to five minutes to acquire a strong
GPS lock. Always choose a flying location with a clear view of the sky to improve GPS signal strength. The following
requirements define a GPS lock:
• Reported horizontal position accuracy
• Reported speed accuracy
• Number of satellites
• Difference between GPS and inertial navigation vertical velocity
If satellite coverage drops beneath a reliable threshold during flight, Solo will automatically switch to Fly:Manual
mode. This mode does not provide the flight-stabilizing GPS functionality, but it still lets you control Solo.
4.7
Home Position
Solo's home position is the latitude and longitude coordinates of the launch point and is used by the autopilot as
the end point of a return-home command. The autopilot saves the home position location to where the motors are
started, assuming GPS lock has been achieved. If Solo has taken off without GPS lock and then achieves GPS lock
mid-flight, the home position will be set to wherever GPS lock was acquired. The location of the home position
depends on GPS signal strength and is usually within one to two meters of accuracy. Always take off from an open
location with a clear path for Solo to return home safely. For home position safety in advanced mode, see Section
8.4.
