Some early
Std. Libelles had top- and bottom airbrakes which should work better.

Mine is one of these. I've also flown a B series in the distant past and
don't think there's much handling difference between mine with top and
bottom surface brakes and the B-series with single surface ones.

Note that most Std. Libelles are B-series, with foam in the wing skins,
water bags, top-surface brakes and a revised tailplane. The first B-
series was probably s/n 182, but the change-over was gradual, starting
from s/n 85.
