Plane model toy / Hracka letadla

EN: The idea was to have a plane with engine, which could hang from the ceiling, and fly around. But, the plane is heavy with not so strong engine/propeller. 
But as a toy for a kid makes fun :-).

1/ print parts (print body sliced, in high 11,81 mm)

2/ glue battery contacts and wires, switch, engine

3/ sold contacts

4/ glue the body part together

5/ put batteries, play :-). The plane could be hanged.

(you can see, how difficult was designing, with many prototypes printed :-)) 

SK/CZ:

Plan bol postavit jednoduche lietadlo s motorcekom, ktore by sa dalo zavesit na nitku, a lietalo by do kruhu (preto som az tak na zaciatku neriesil hmotnost). No, ale ukazalo sa, ze lietadlo je tazke, motor s vrtulou nema taku silu, aby ho potiahol dopredu.

Ale stale je to dobra hracka pre dieta - zapne si motorcek, zoberie do ruky a “lieta” :-)

1/ vytlacte diely (trup tlacte rozdeleny, vo vyske 11,81mm. Vid 3mf subor)

2/ prilepte kontakty na baterie, dratiky, vypinac, motor.

3/ spajkujte/spojte kontakty

4/ zlepte trup dokopy (staci par kvapiek, ak by ste ho neskor rozoberali, napr. kvoli vymene vrtule, motora, …)

5/ vlozte baterky. Mozete sa hrat :-).

Update 31.3

Added new propeller. Thanks to https://www.printables.com/cs/social/91634-meister-edel/about
for providing me a design of toroidal propeller, suitable for my plane.
 

Vdaka pouzivatelovi meister-edel za poskytnutie dizajnu pre novu, efektivnejsiu vrtulu.
