You have probably seen their film series called "Living FPV". I propose you today 2 new amazing videos. The first one is "just" the immersion world record with 47 km !!!! they use a flying wing for that:
I personnaly prefer the second one which is absolutely superb. An immersion flight in patrol with a 8.4 m ASH31 sailplane !!! Using the Go Pro I can tell you that the flying wing is very very close to the sailplane !
