UAV (3) High-altitude video using IMU autopilot
The video demonstrates testing of the autopilot display module when flying in automatic failsafe mode,
known as Return-Home.
In order to obtain high quality video, instead of using wireless link, a light personal camera
has been temporarily attached on the nose of easystar.
Before flying, make sure you are far from any aircraft routes and get informed about air traffic laws.
The video also shows typical automatic landing, possible in calm winds and flat terrain. It is clear that UAV at that price range will not be used from dedicated airfiled. Because of the need to keep wings level during touchdown, the only thing that is achievable in as system without 3D wind speed mapping, is anemic loiter above groundsite or a parachute that will cause many mishaps due to hasty assembly during pre-flight. As EasyStar has very nonlinear response in function of throttle and airspeed, it is already an achievement to have a loiter area around 100m (elongating to 200m in case of wind). The rest is luck, you need a clean landing site. You can also look at that this way: whatever happens, the autopilot provides reilable descent. If there is a party nearby, you are free to attend.
The autopilot provides 2 options: land at takeoff point or land at fixed GPS position. You can use the second alternative in order to protect the plane.
