Mechanics of flight
After a decade of having experience building RC Gliders, my passion grew ever so quickly. My first DLG glider was the Mini Topsky. I flew her many times, 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 surfaces 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. (beneficial) Drag: The aerodynamic force exerted on the wings parallel (in line) with the oncoming airflow.
Ready To Fly FireFly RC Glider
Handmade precision DLG slope radio controlled RC glider. 2017 design
Flight of theFireFly a 33.5" wingspan soaring rc glider. Use any small 2-4 channel receiver. At 91 grams and 33.5" wingspan, this here FireFly is the "floatiest" glider but yet aggressive. An hour of flight on a single 300mAh rechargeable battery. Magnetic hatch
Removable wing/tail using two nylon screws for easy carry. Pod is structurally stiffened with carbon fiberglass tow and epoxy.
