2) With large span gliders, opening the airbrakes causes the wingtips to
bend up. We fitted a second paddle to our Nimbus 2 airbrakes and I did the
test flight in which I was supposed to fly up to Vne (135 knots) with the
brakes extended. By 95 knots the wings were bending up so much that I
started to fear for the structure and didn't go any faster! I resolved that
should I ever lose control of the speed, I would slow it down by pulling g
rather than opening the airbrakes.

I don't understand your choice ! if there is a risk at high speeds, the
best choice to avoid it is to avoid these speeds, and that's what the
airbrakes are for, aren't it ? Pulling g's after loosing control is the
best way to break any aircraft...
