Electric, EDF & Silent Flight

 

General Information

Flying from our well-mown grass runway and using either 2.4 GHz or 35 MHz frequencies on even numbers, we fly both hand-launched and undercarriage models from the runway.

Electric Sport and Scale

This is the fastest growing area of aero modelling worldwide. It is environmentally friendly with no direct pollution and low noise impact.

Most purpose built electric models are either moulded foam or lightweight, balsa built models but most traditional IC powered models can be converted to electric due to the huge variety of modern brushless motors and lithium polymer batteries. The benefits are quiet operation, reliable power, lots of torque from low rpm and the ability to reverse thrust. The downsides are limited flight times, long battery charging times, and potential fire hazards of charging unattended Lipo batteries.

Multi-engine type models like the trio of B-17s above are far easier to fly with electric power than trying to tune IC engines to matching rpm outputs.

Electric Ducted Fan (EDF)

Electric Ducted Fan models provide the look and performance of jet model types without the noise and cost of operating a gas turbine model.  Most are made from moulded foam meaning they are lightweight, easily portable and available in many designs. The disadvantages are limited flight duration. They can be flown on-site but only after they have been noise tested and registered with the Club EDF Liaison. You should check with the Club before purchasing an EDF model to see if it is suitable for the site.

Electric Thermal Soaring

Electric thermal gliders use a motor with a folding prop to get the model to altitude. Once at height, the motor is switched off either by the pilot or by an onboard altimeter at a pre-set height. The prop folds flush to the fuselage and the glider is flown as a thermal soaring glider. This does away with the need for a long bungee cord launcher or an aero-tow from another powered model. If the model should lose altitude then the pilot re-engages the motor and climbs back up rather than having to land and relaunch.

Slope Soaring

Some of our members fly slope soaring models from a variety of local sites, such as Liddington Hill, Barbury Castle and Uffington White Horse Hill, depending on the wind direction. These sites are ideal for various type of sport and scale gliders.

Slope soaring is a unique discipline where you can fly anything and use the lift of the wind to fly at close quarters, to see how you and your model reacts to the elements of the day.
