Easy and fast swop between a hybrid and fully electric version is the key feature of smartflyer. The energy storage in the nose of the aircraft can be changed by anyone within 15 minutes, depending on the mission. Either the hybrid range extender or a battery pack is installed. This way you can easily fly 800 km or fully electric for two hours. The propeller is not a nuisance at the front of the cockpit. This makes smartflyer the ideal training platform for future jet pilots.
