Aircraft with foldable tail assembly

A foldable tail assembly for an aircraft comprising:

• a horizontal stabilizer;
• a pair of right and left fins hingedly mounted to the stabilizer so that the fins lay flat over the stabilizer during periods when the aircraft is not flight-ready, and so that the fins are erected above the stabilizer to form a triangular configuration when the aircraft is ready to fly;
• the ends of the fins that are remote from where the fins are hingedly mounted to the stabilizer including a cooperative joint structure for joining together the ends when the fins are erected to the ready-to-fly orientation, whereby the fins when erected form a triangle having the portion of the stabilizer between the fin-mounting hinges as the base of the triangle and the fins as the sides of the triangle;
• an elevator hingedly connected to the stabilizer;
• and
• a rudder hingedly connected to each fin.

An aircraft comprising a fuselage, wings, a tail support structure, and a tail assembly, said aircraft comprising:

• a stabilizer supported by said tail support structure;
• a pair of right and left fins mounted with respect to the stabilizer so that the fins lay flat over the stabilizer during periods when the aircraft is not flight-ready, and so that the fins are erected above the stabilizer to form a triangular configuration when the aircraft is ready to fly;
• and
• the ends of the fins that are remote from where the fins are mounted with respect to the stabilizer including a cooperative joint structure for joining together the ends when the fins are erected to the ready-to-fly orientation.
