12 km cross-country flight (7 waypoints) with the Feiyu-Tech 31 Autopilot system. (NAV mode is switched on at 0:38 in the video and off at~13:40).

Note that when turning north into crosswind section (~ 8:00 in the video) the AP obviously over-adjusts a bit (or the plane gets pushed around too far) and has to turn back twice to get back on track. This behaviour nicely demonstrates that the FY-31 AP does not just try to meet preset waypoints but aims to follow straight tracks in between them.

The 250 cm (98,5'') wingspan "Ogar" distributed by Wings Maker/Pichler is a very well made semiscale model of the original polish motorglider. Like the original it is a very effective plane and excellent glider. It has a low wing load and huge "cargo bay" under the cockpit - very good for FPV and photo equipment. The Boost 18 pusher brushless motor with a 9/6 foldable three blade prop takes about 200 mAh per minute out of the 3S 3.300 Lipo.

Filmed with key cam 808 #16 V2 (integr. wide angle lens). Additional #11 wing cam (magnetic wide angle lens) switches off due to fading battery after just five minutes.
