The propeller machines with rubber motor are ingeniously simple: they fly very far and the motor does not need a bit of electricity. This is because it gets its energy from a rubber band attached to the propeller. To ensure that nothing happens to the small power packs during landing, he is reinforced all around. Before take-off, turn the propeller by hand until the rubber band inside the aircraft is completely tensioned.
