The Return Home button allows you to bring your flight to an end by recalling Solo to its launch location and landing. Keep in mind that Return Home requires enough battery to get back to the launch point, so if you need to end your flight immediately then land manually or hold the Fly button. Return Home requires GPS lock prior to takeoff.

warning_triangleSolo does not avoid obstacles during its journey home, so make sure the return path is clear before activating Return Home.

Smart Return Home

When a call to Return Home is triggered, it is critical for Solo to make a swift and safe journey back to its takeoff point. Among the factors involved in balancing these priorities are:

  • The farther away Solo is, the higher the likelihood that it could encounter unforeseen obstacles (buildings, trees, etc.). Because of this, longer-distance scenarios benefit from climbing in altitude before traversing back home.
  • The closer Solo is to the overhead proximity of the Home Position, the more confident we can be that there are fewer obstacles in the return path. This means it’s safer for Solo to just land without needing to rise first.

To help eliminate unnecessary ascents in favor of more efficient return flights, we developed the “Cone Zone.” cone_zone
The Cone Zone represents an area that is least likely to be filled with problematic obstacles. The shape of this cone is based on a 1-run-to-3-rise ratio. So as your altitude increases, so does the area of the cone. (And you thought you were done with algebra!) Once Solo reaches the boundaries of the cone or is already within the cone, then its main priority is to traverse to directly over the Home Position and land.

Obstacle-Free Cone Zone

The following examples walk you through the different flight scenarios and how the Cone Zone affects the Return Home behavior of each scenario.

Case #1: Above the Return Home Altitude

When a call to Return Home is triggered and Solo is flying above the Return Home Altitude (default: 25m), Solo:

  1. Climbs 10m
  2. Traverses to the Home Position
  3. Descends and lands


Case #2: Within the Cone Zone

When Solo is within the Cone Zone and Return Home is triggered, Solo:

  1. Climbs 2.5m
  2. Traverses to the Home Position
  3. Descends and lands


Case #3: Outside the Cone Zone

The radius of the Cone Zone expands at a 1-run-to-3-rise ratio. This means that the Cone radius is directly related to the Return Home altitude. As your Return Home altitude increases, so does the radius of the cone. If Solo is far enough away from home, it will then be outside of the cone In the occurrence of a call to Return Home, Solo:

  1. Either climbs to the boundary of the cone or to the Return Home Altitude, whichever happens first
  2. Moves to the Home Position
  3. Descends and lands
