To build templates of the screw (side view) for a given shape of the blade (top view) and the step there are two main methods of calculation: analytical and graphical. Usually based on the following characteristics: diameter, the relative width of the blade and step. Since the amount of slip is difficult to consider in advance, based on the geometric pitch.CALCULATION OF SCREWS

Control line aerobatic trainer model airplane. In our time, control line model airplanes is significantly different from traditional sports is Now for the creation of models is often taken is not the one who is going to participate in sports, and those who just want to experience the magical feeling of power over the obedient cord pilotami. With considerable help novice modelers have model shops where you can purchase the complete set of elements for Assembly cord models and individual parts and blanks for their manufacture. There are trading firms that distribute their goods by mail.
Motorbike and car – the cars are different. First and foremost, by the level of comfort. Is it possible to combine the advantages of two-wheeled transport with the convenience of the car?
