Hello everyone
I am a schoolboy, I am 13, very much interested in engineering and aircraft.
This is not my first project, but the first that I created and launched myself, from scratch, based only on the Internet and the available models, so do not swear at the ill-conceived places, although as for me, I almost brought it to perfection.

Description of the project itself:
The main feature is the removable bottom, I have a camera there for shooting, but you can install other equipment.
The keel and wing are removable, the wing is on latches, the keel is on a screw, take a regular ballpoint pen, stretch the spring to 5-6cm, and cut into pieces of +-12mm, insert this spring between the latch and the wing.
The ailerons and the latch are attached to pieces of filament. Attach the ailerons to the wing and to each other so that the connection can be disassembled into wing
