 Project Condor regroups several smaller projects with the aim of creating a fully open source quadcopter.
 
 The goals are:
+
 - A large (1m diameter frame), powerful quadcopter.
 - Modular, rack-like design that enables easy addition and removal of modules (e.g. camera, on board computer, extra batteries)
 - Self-assemblable flight controller using readily available components
