Advice on Full stalls!

I'd been wanting to do full stalls for ages. Here in Turkey anyone who is half decent has done them, and I've flown at Ölü Deniz a few times now, so it was well due.

I took off from the 1700m take-off and managed to thermal up 1,200 ft which was a first. I glided from this altitude to over the 1968m summit along the ridge, and bounced around a bit in quite strong air, and then head out over the sea (thinking it would be safer doing a stall!), arriving with 1,500m to make use of. I did a couple of B line stalls first, and then went for the full stall. A wrap, slow down speed, pull down to try to find the stall point, and then WHAPPP! Total loss of control for a heart stopping second, falling backwards, losing sight of the wing behind you completely, arms locked down as though your life depended on it, and then the wing re-appears, nice stable position with wingtips tucked above you. I recorded I was falling at about 16 m/sec. Hold it for a while, then release, and whoooh big SURGE forward, jam on the breaks, then another surge and then stable flight again. Heart pounding. Now try again: pull down symmetrically, fall and chaos, wing stable overhead, raise hands slowly to chest height to inflate the wing-tips a bit (almost tail sliding here which Matt thought I should try), and then release, surge, break, and away - nice and cleanly. Much more control than the first time. Sweet.

Advice for doing the stall. DO A B LINE STALL FIRST. It's like half way between the two, but it's much safer. In fact my Gangster is less stable overhead when it's B-line stalled than when it's full stalled - so it's good practice for releasing the breaks when the wing is in front of you since the wing oscillates a lot. I measured a descent rate of 6m/sec with a B-line stall. It feels like you're falling faster.

Here's a guy doing a B-line stall on YouTube for an idea.

Here's a guy who screws up by releasing the breaks as soon as he stalls.
