Taifun 17E and 17EII
the differences



It's a question we receive once a month from people all over the world: "Can you tell me what are the major differences (if any) between a Valentine Taifun 17E and a Valentin Taifun 17EII motorglider?". To answer this simple but obvious question we summed up the main differences.

  1. A Taifun 17 E II is equipped with an electric/hydraulic retractable gear, while the gear on a 17 E is operated by hand. In case of an emergency with failing hydraulics, the gear of a 17E II can be geared down automatically by switching off the pressure holding up the gear. In case of no pressure, the gear will come down by opening a pressure lever.

  2. A Taifun 17E II has a lower TOW, because of absence of metal parts for the gear, thus allowing more weight/load.

  3. A Taifun 17 E II is equipped with gear indicators, gear warning and emergency gear, all absent with a Taifun 17E.

  4. A Taifun 17 E II has double speed brakes, allowing steep descents and short field landings, while a 17E is equipped with single speed brakes.

  5. With a Taifun 17E II all operating switches and handles are concentrated in the middle of the instrument panel, while a 17E has several handles (breaks etc.) aside the seats.

  6. With a Taifun 17E II the way the bolt mechanism attaching the wings to the fuselage is slightly different from a 17E. As a result of this difference with a 17E the wings can be folded backwards after pulling them out of the fuselage, while with a 17E II the wings can only be detached from the fuselage. Because the bolt-connection mechanism (pipes) from a 17E cannot be removed, a 17E has slightly more weight than a 17E II.

  7. While flying the nose wheel from a 17E will be retracted completely inside of the fuselage, while with a 17E II half of the nose wheel will stay outside of the fuselage. It's done that way while in case of an emergency landing a 17E II is able to land on the nose wheel and the tail wheel without having to gear down all three wheels.
