Design and development
The Apis-Bee is a second generation derivation of the original
Pipistrel Apis design. The company explains the name of this version, "In some countries, the name 'Apis' is trademarked, so we are unable to use it. These countries are, as far as we know, the following: Germany, Austria, Switzerland and some Scandinavian countries. There, the aircraft is marketed as 'Bee'. We chose this because 'Apis' in Latin means a bee."
The aircraft is made from composites, predominately
