3km range flight, automatic path following in sunny yet turbulent weather.
Sidewinds and up/downdrifts are present. The plane has navigated fully
autonomously using only 3 waypoints out of 128 possible.
The waypoints were absolute, found using GoogleEarth.
A camera has been attached in the nose. The takeoff was manual. After
trimming out the plane for changed aerodynamics and center of gravity the
autopilot has been enabled in return-home mode. After a short loiter,
MODE_CHANNEL on the transmitter has been flipped and the mission has begun.
As you can compare with simulated flight the real plane climbed slower due
to extra load and drag. You can observe also the effect of turbulence. The
video has been stabilised by software after the flight.
The landing was fully automatic, the transmitter has been turned off after
some 1min of flight. After next 3min the plane disappeared out of sight and
returned 10 min later. Using FPV equipment and RVOSD FLEXIPILOT output you
could track the plane all along the way, but this time I have chosen to put
classic camera in the nose, in order to test it.
before launching such a mission it is important to setup RETHOME conditions
and launch a simulation BEFORE starting the takeoff as discussed in
Also look at the similar flight in the winter, including the photomapping of the same area
Loading more stuff…
Hmm…it looks like things are taking a while to load. Try again?
