I'm going to have to get into FPV after seeing your footage. I've always felt flying RC is vicariously satisfying the desire to fly. Looking out the front of a glider through a camera brings that feeling even closer.
You should definitely try it, it's heaps of fun! Quite a stunning view from up there too, I might add. There's a really cool thread over here about scale cockpit FPV with head tracking, if you're interested.
I flew my glider again today, but I had an elevator trim issue so I cut the flight short. I started flying around downwind of myself to lose altitude, but I flew over a herd of sheep that must have triggered a thermal (or were farting heaps ). After deciding to keep flying instead of landing, I flew back and forth through the lift. It was very hard with the elevator not being trimmed, but I managed. I started flying around the area at maybe 12m altitude or so, but a few minutes later it was at least double the starting altitude! I am not sure if this will ever be a great "thermal machine", but today proved that it can be done. I am building a Simple Soarer to teach my little sister to fly on, so hopefully I can learn to thermal properly on that.
