The 303 wing featured innovative interconnected trailing edge dive brakes-variable camber flaps.

The glider had automatic connection for all controls: ailerons, elevator, air brakes and water ballast.

It was available with a tow release in both the nose and near the centre of gravity; in-flight adjustable rudder pedals and seat back.

It is by all accounts a nice-handling, comfortable and pleasing aircraft, but a little less performing than the contemporaneous Rolladen-Schneider LS3 and ASW 20.

Therefore, the Mosquito (and the Schempp-Hirth Mini-Nimbus that shares the same wing) did not do well in top-level competition, neither did it find the large commercial success of the Libelle.
