RC paragliding uses a radio-controlled paraglider model. The paraglider acquires its wing shape by filling with flowing air during flight. Control is exactly the same as with a large paraglider, i.e. by braking on the side we wish to turn towards. During landing, we brake on both sides at the same time for the softest landing. The pilot figurine has servos built into its body which control the arms. These in turn pull the brake lines and steer the canopy. The glider is usually controlled by a four-channel RC set (transmitter) with two channels dedicated to the servos for controlling the arms and another to controlling the motor. The fourth channel is needed when using a speed bar system or when discarding the reserve parachute. For the purposes of slope soaring, a three-channel set is all that is needed. In fact, even a two-channel system will do nicely unless using a speed system or discarding a reserve.
PARAGLIDING IN GENERAL
Paragliding is an air sport. Movement through the air is done using a paraglider wing – a glider canopy which falls into the category of sport flying vehicles. An experienced pilot can glide through the use of ascending air currents. Ascending currents can be “mechanical”, where the air current rises against a terrain obstacle (slope), or thermal, where hot air rises from the surface.
A paraglider is a sport flying device without a rigid internal structure. As the canopy moves, air enters its interior, inflating it to aerofoil shape. The difference in speed between the air flowing across the upper side and air flowing across the lower side of the canopy creates aerodynamic force which enables controlled flight.
The paraglider consists of a canopy, lines and risers. The canopy consists of a upper and lower side, among which there are reinforcements and ribs in the shape of airfoil.
The paraglider lines system is divided into three main parts: main lines, branching (also called gallery lines) and brake lines (brakes). The lines are straightened in rows behind each other. The rows are usually designated by upper case letters A, B, C. The A line is tied to the leading edge, the B and C lines continue to the trailing edge, and the brake lines are tied directly to the trailing edge.
The ends of all lines are made into risers of the individual rows A, B, C, which are attached to the landing gear (paramotor, trike or harness) using karabiners. The only free ones are the brake lines that lead through D-rings on the straps to the pilot's hands.
