The Esnault-Pelterie R.E.P. 1 and the R.E.P. 2 were experimental aircraft built and flown in France in the early 20th century by Robert Esnault-Pelterie. These aircraft are historically significant because they were the first to employ a joystick as their main flight control. The R.E.P. 2 differed from the R.E.P. 1 in having a slightly different undercarriage (of the same general arrangement) in addition to a large ventral balanced rudder. Tests with the R.E.P. 2 commenced in June 1908, and on June 8 a flight of 3,900 feet was made, reaching an altitude of 100 feet, setting a height and distance record for monoplanes.
