I want to share the first flight of the third development of a fixed wing aircraft for autonomous flight.
This design was made entirely with composite materials and the molds made with 3d printers.
tests resulted in great aerodynamic efficiency and stability and maneuverability
final weight with full payload is 2.6 kg.
for the flight he was ballasted with the final weight for flight.
we estimate endurance of 90 minutes with 10,000 mA and 4S
