| 説明 | I bought this helicopter out of curiosity from ebay. I was amazed at its cheap price and the superb way in which it flies (under remote control) The secret is in the twin main rotor. The upper blades are weighted so that they act as a gyroscope so as the copter tilts they rotate in a fixed plane. Small links to the lower flexibly mounted blade counteract any tilting movement the copter may make. In flight the model stay in a perfect hover and by varying the tail rotor thrust the copter can be spun around. Because it is slightly nose heavy the model flies slowly forward thus the tail rotor gives a sort of directional control . It may be viewed in flight here. flickr.com/photos/elsie/376688627/You wanted to know all this didnt you!!!?! |
