ABSTRACT:
A light aircraft having a parachute-wing, a single propeller, and means for controlling the direction and speed of the aircraft by simple control lines to the canopy. The carriage is supported by at least two support lines which are secured at attachment points spaced apart laterally with respect to the fore and aft direction of the craft. By ensuring that the support lines are of different lengths a side-to-side suspension bias is created which compensates for the propeller torque reaction. This is a permanent adjustment which allows the aircraft to be balanced so that control of flight may be effected without difficulty. Preferably, the carriage is constructed to use a longitudinal base strut on which a foldable tricycle under carriage is mounted. An upright strut is pivotally mounted to the base strut. The frame of the pilot's seat is used as an integral structural member which rigidly links the base strut to the upright strut in the running condition. The two struts and the sear frame form a triangle.
