ABSTRACT:
An aircraft of the Canard type in which a first airfoil is attached to an aft fin portion of the fuselage at a higher elevation than a second airfoil which is attached to the fore portion of the fuselage. The second airfoil extends outwardly and rearwardly to meet the first airfoil whereby a triangular configuration is formed in plan view and in front elevation view. The airfoils may be flexible; simple cable controls may be provided to control the aircraft so that even inexperienced pilots can easily operate the aircraft. The triangular configuration ensures a lightweight and inexpensive yet rugged and strong aircraft. The aircraft may also include a split rudder and may be hinged for folding to facilitate storage and transportation.
