Bruno,

Great video as usual. I have some hours on in the 27 its a beautiful
glider.

My only comment is that *I close the brakes immediately the tug is rolling
and there is no risk of running over the rope and keep my hand very close
to the release in case of a wing drop, especially with water and especially
with a X wind!

Believe me its amazing how fast it can start to go round if the wing goes
down and digs in.

This experience cost me no more than a bit of pride but had i had to move
my hand from brakes to release it might have been different.

Looking forward to the next Vid!

Actually I find that on the 27 as with many other gliders, half
airbrake substantially improves aileron authority. So I keep half
brake out until I'm really sure I have aileron control, then close and
lock the brakes, move my hand to flaps and transition from flap 2
(which gives best aileron control) to flap 4 and take off. I know
exactly where the release is and how to get there, of course. And
since your hand is on the airbrake, it is impossible to take off with
brakes open.

Also from experience -- one day I closed the spoiler just a little too
soon, lost aileron control, a wing went down and I got to use that
release in front of a whole contest grid! Good thing it was a big
grass field.

Needless to say, making sure the ballast is sloshed so the wings are
balanced, the upwind wing is held a little low, and the wing runner is
an olympic sprinter helps too. I recently couldn't persuade a wing
runner to hold the upwind wing low with predictable consequences.
