How to make a mini helicopter
Hello my dear friends! Roman is with you as usual. In today’s video I’d like to show you how to make a nice toy for children, a mini helicopter or a so called flying vane.
First, we need a plastic ruler for 20 cm, pencil of 15-20 cm, one screw, a piece of hacksaw, one drill, super glue and a lighter.
First, make a hole near the mark 20 with the screw-bolt or a heated nail. Then, make half centimeter cuts at both sides near marks 12 and 8.
Heat the cuts with lighter and form vane by bending it sideways. Make sure that the bends are equal.
Now take a pencil, make a hole to avoid its cracking during twisting the screw. Set the right side of vane up and the left side down. Half twist the screw, stick it with the super glue to prevent turning of vane and pencil, and twist the screw till the end.
That’s all. A simple and interesting toy is ready. It flies very easily by turning the pencil between hands quickly. That’s all for now. Thank you very much for your attention. Bye-bye everyone!
