Not often, but sometimes: spin rubber motor on the model, and suddenly it breaks. And it brings a lot of trouble. However, more recently, the fuselage of this “accident” is not suffering — its the working part on rezinomotornaya model aircraft are now in the form of a solid tube made of aluminum or fiberglass. But the propeller is still defenseless. Devices used to protect it from breakage, disks or rectangular plates of sheet aluminum not withstand strong impact. In addition, they are massive and awkward to use.SIMPLE AND RELIABLE

The hovercraft is. Building a vehicle that could move on both land and water, was preceded by a familiarity with the history of the discovery and the creation of original amphibious machines, air cushion (WUA), the study of their fundamental devices, comparison of various designs and patterns.
