"Effects of the Present Invention" As is clear from the above explanation, the present invention provides the following effects.

(1) At least two reinforcing aggregates protruding from the left and right sides of the fuselage were placed at a predetermined distance apart, and the left and right wings were fixed to these reinforcing aggregates.
The left and right wings can be firmly fixed to the fuselage. Therefore, it is possible to prevent the left and right wings from being damaged or displaced due to air resistance during flight or impact upon landing. Therefore, it has excellent durability and can be easily thrown.

(2) Two reinforcing aggregates spaced apart by a predetermined distance are attached to the fuselage in a penetrating state, so the left and right wings are constructed by two reinforcing aggregates placed in the front and rear directions. It can be fixed so that it cannot be rotated forward or backward. Therefore, sufficient lift can be applied to the left and right wings during flight.

(3) Since the fuselage outer panel and the left and right outer panels are integrally formed, the fuselage and the left and right wings can be more firmly attached.

(4) If at least two or more reinforcing aggregates passing through the rear of the fuselage to the left and right are used for the horizontal stabilizer, the horizontal stabilizer can always be held horizontally.
