Cuban Eight
Encyclopedia
A Cuban Eight or Cuban 8 is an aerobatic figure eight
maneuver for fixed-wing aircraft both full-scale and radio controlled.
Variations include the Half Cuban Eight and Reverse Half Cuban Eight, intended as directional changes and which are listed below.
According to the Aresti Catalog
, a Cuban Eight is performed thus:
5/8s of a loop to the 45 degree line, 1/2 roll, 5/8s of a loop to the 45 degree line, 1/2 roll, 3/8s of a loop to level flight (half of the Cuban Eight is called a "half Cuban Eight", and the figure can be flown backwards, known as a "Reverse Cuban Eight").
with the difference being in the location in the loop at which the roll is performed. The roll in an Immelmann turn is at the top of the loop.

Half Cuban Eight
From level flight, 5/8s loop to the inverted 45° line, 1/2 roll to erect down 45° line, pull to level flight. The move is similar to an Immelmann turnImmelmann turn
The Immelmann turn refers to two different aircraft maneuvers.-In aerobatics:In modern aerobatical parlance, an Immelmann turn is an aerobatic maneuver of little practical use in aerial combat, and is a different maneuver altogether from the original dogfighting tactic of World War I from which it...
with the difference being in the location in the loop at which the roll is performed. The roll in an Immelmann turn is at the top of the loop.
Reverse Half Cuban Eight
From level flight pull to the 45° up line, 1/2 roll to inverted 45° up line, then 5/8s of a loop to level flight.
