A bit late after the fact but I have been meaning to do a short post about the latest UAV test flight. A new airframe was developed as part of the European 2Seas 3i project. 2Seas is an EU funded project looking at high reliability UAVs for civil and maritime surveillance.
Its a twin petrol engine aircraft with twin carbon fibre booms, an H-tail and modular payload pod. These pods can be specified to carry a range of cameras and overall endurance can be 12 hours or more. Twin on-board generators maintain the avionics capability for extended duration flights. All up weight is about 20kg.
