Abromovich flyer
Type	Early experimental aircraft
Manufacturer	Vsevolod Mikhailovich Abramovich
Designed by	V. M. Abramovich

The Abramovich flyer was an early aircraft built by Vsevolod Mikhailovich Abramovich in 1912, based on the Wright brothers' designs he had seen while working for their German subsidiary. Differences from the Wright designs of the time included wheeled undercarriage, and conventional empennage replacing the canard the Wrights used. Abramovich retained the wing warping technique the Wrights used for control of the aircraft, but controlled this with a control stick rather than the harness of the Wrights' design. Given the legal action that the Wrights were taking at the time against a large number of people they felt were infringing on their patents by building far less similar aircraft than this one, possibly only Abramovich's untimely death in a crash the following year prevented him from experiencing similar action by his former employers.
