I had a Slingsby Kestrel which had flaps, 2 lots and airbrakes. The
best that could be said about the airbrakes is they made a nice
noise. It also had a tail parachute which was very effective, if it
deployed. The tail parachute was in a shaped box on the bottom of
the rudder. The technique was to select the deployment and then
waggle the rudder from side to side to encourage it to deploy. This
worked most of the time. I used to start an approach where I
intended to use the parachute from 600ft. If it did not deploy I had
enough height to do a 360 deg turn on finals to loose the height.
