CTD - RC Electric Delta
The CTD is an electric model aircraft that is easy to build and straightforward to fly. It is cheap to construct and great fun to operate from a small flying field or park in relatively calm weather.
The model can be looped, although it is in no way intended to be aerobatic. The real joy of the CTD comes with its excellent slow-flying characteristics – all thanks to its delta plan-form.
The electric motor used on the prototype is a relatively inexpensive brush-type motor with an integral reduction gear and mount.
Alternative electric motors can be installed and it shouldn't be too difficult to fabricate an appropriate plywood mount to fit most types of electric motor directly to the aircraft's keel.
The micro-size radio gear simply sits on top of the airframe. A long strip of velcro is used to attach the battery pack, thus allowing various fore / aft positions, to ensure the correct "centre of gravity" location, no matter what size battery is used.
