The '''ACBA Midour''', '''Midour 2''' and '''Midour 3''' are a series of glider tugs manufactured by the Aéro Club du Bas Armagnac in France, and named after the Midou River.

==Design and development== The Midour is a double-seat, low-wing monoplane of conventional configuration, fitted with a fixed, tricycle undercarriage. Developed in the workshop of the ACBA using the wings of a Robin DR400, the Midour first flew in 1993<ref>{{cite magazine|last=Lert |first=Frédéric |title=L'ami Midour - Un stackhanoviste de l'aérien |magazine=Aviasport |language=French|date=May–June 2021 |issue=774 |pages=26–31 |url=https://www.calameo.com/books/0069472741a0e3ca8b74d}}</ref> and four additional examples to the original design have been built, along with two modified versions.

Although the Midour is sometimes equipped with only a single seat, a passenger can be carried behind the pilot, to assist in the release of gliders being towed.
