This is generally accomplished from a flat flying field with a large open space. Sod farms are also perfect for this type of flying. Gliders are normally flown this way. The general idea is to find thermals (they are bubbles of warmer air that are rising), preferably wind-up and then you have to ride the thermal back towards yourself.
On a hot summer day, you can catch wonderful thermals that are perfect for a morning glide. All you have to do is watch closely for a lift in your glider. Once you see it, turn into the rising wing and you may well find your thermal.
You must launch the RC glider toward the thermal and gain maximum altitude at the start of the flight.
This is probably the simplest form of gliding since all you have to do is to basically toss the glider into the breeze, directing it to the slope (can be a hill, etc.). Flight times can be as long as the wind continues to blow the glider into the direction you want.
Just remember when doing this, the wind must be blowing towards the slope with no trees and buildings. You should also be near the top of the slope since crashing your glider is a possibility when the wind blew too hard. The flatter the land at the base of the slope, the better turbulence free lift is generated. A slope facing the ocean or a lake is also an ideal place.
The way to do this is simple enough: hold the glider on one hand and the transmitter on the other hand. Throw the glider towards the wind and then gently direct it to the direction of the wind.
This is the latest type of soaring, and is not for those with a faint of heart. This type has a high attrition rate since it provides high altitude. It also has the fastest speed for anyone who ever owns an RC glider.
To conduct the dynamic soaring, you have to fly at the back of the slope. This is weird for some since normally, you have to fly at the front of the slope. An ideal slope for dynamic soaring is a ridge with a sharp slope on both sides. The front face has the normal rising air and the back slope has still air but no wind. At the top of the ridge, there must be a boundary layer.
A glider flying on dynamic soar flies on an inclined loop, close to the surface of the backside slope. As the glider flies from the back slope towards the front slope, it will slowly gain energy. It will then cross the boundary layer on its way down the slope. By that time, gravity is imparting energy as the model dives down the slope and back up again.
The key to dynamic soaring is for the glider to have enough power to complete the loop on and on again.
It is very important for RC hobbyists to educate yourselves on what and what you can do with your RC toys, especially the RC Glider as it combines the fickle weather and your skills as an RC pilot. These types of flying must be practiced again and again in order to be perfected, so take the time out and try your hands on some of these gliding techniques.
