In the case of RC gliders and sailplanes, this lift is typically provided by updrafts in the air, also known as thermals. Thermals are essentially bubbles of warmer air that rise, providing an updraft that the glider can ride to gain altitude. Learning how to locate and utilize thermals is a skill that can take some time to master, but it is crucial for maximizing your glider’s flight time.

Glide: Once your RC glider has gained altitude and is no longer in an updraft, it begins to glide. Gliding refers to the balanced state where the forces of gravity pulling the glider down and the lift generated by the glider’s wings are in equilibrium, resulting in sustained, level flight. The key to a successful glide lies in maintaining a gentle descent rate and forward momentum, which is achieved by proper control of your glider’s pitch and speed.

Landing: The final phase of your RC glider’s flight is the landing. The goal here is to bring your glider down safely and smoothly. As you approach your landing area, gradually reduce the glider’s altitude and speed. One effective technique for landing an RC glider is to use a method known as ‘flaring’. This involves pulling back on the elevator control slightly just before touchdown, causing the glider to level out and touch down on its main wheel or skid. It’s important to practice landing techniques in a variety of conditions to become a proficient pilot.

In all these stages of flight, it’s essential to be patient and practice consistently. Even experienced pilots continue to refine their understanding and control of lift, glide, and landing. And remember, every RC glider has its unique flight characteristics, so take the time to familiarize yourself with your particular model’s behavior in different conditions.
