UltraLight DLG Slope RC Gliders
Learning the art of catching thermals and understanding wind flow/direction, the use of rudder to control yaw, air speed, increasing lift increases drag, fundamentals of flight.
The difference in pressure between the top and bottom surface of an airplane wing results in the force we call lift. Aerodynamics divide the force produced by a glider's wings into two parts. They call these “Lift” and “Drag”.
Lift: The aerodynamic force produced by the wings perpendicular (at right angles) to the on coming airflow.
Drag: The aerodynamic force exerted on the wings parallel (in line) with the oncoming airflow.

What is the purpose of lift? It is to hold an airplane up in the air by countering the effects of weight (gravity). The simple fundamentals of weight (W = mg) for officiant flight has been lost and overlooked in today’s model gliders and airplanes. The weight of an airplane plays a crucial role not only when it comes to the thrill factor of soaring but something as basic as fight time and thermal lift. Most models are manufactured using molded EPO foam, which is extremely durable but at a cost, its mass.
A glider with the least amount of weight has the potential to gain altitude with ease.
