Successful high altitude (>100m AGL) position hold tests flights with an optical flow sensor on a Tricopter (OFT) UAV.

Tests flights conducted:

1) The OFT has been set to a fast climb rate at above 100 m AGL in hold position mode with only the throttle command.

2) The OFT has been set above 100 m AGL and a 360° turn has been done (wind 14 km/h from SE) with only the yaw command.

3) The OFT has been set to a fast descend rate from 100 m AGL in hold position mode with only the throttle command.

All the tests flights have been recorded with a GoPro HD Wide video camera
