3D-flyer
From Wikipedia, the free encyclopedia
A 3D-flyer is a small, lightweight, aerobatic, electric radio-controlled airplane. 3D-flyers have thrust that is greater than the weight. This enables the model to climb vertically at constant or increasing speeds, hence "3D". It also allows the model to fly with the wing partially or full stalled, hovering on the prop thrust. They are often called "shock flyers" after the original Ikarus Shock Flyer.
3D-flyers are usually constructed very simply with low weight in mind, often with Depron sheet foam using the most lightweight radio control equipment available. They have aerobatic designs with very large control surfaces. This sort of design makes them very affordable for people wanting to perform aerobatics without the huge costs usually associated with larger aerobatic planes.
