Methods and systems are provided to allow a traditional fixed wing aircraft to perform standing takeoffs and spot landings. Methods and systems relate to a leg undercarriage system that allow an aircraft to take off from a stationary position and to make a spot landing. Methods and systems include an attachment to an aircraft fuselage and one or more leg links and a foot in contact with the ground, a power spring to store energy for propelling the aircraft, a quick release hook to hold the leg undercarriage in a prelaunch position, and an actuation source to move the aircraft to a position that triggers the quick release hook to release and cause the power spring to release its energy and quickly transition the leg undercarriage system to a fully extended state, thus imparting velocity and altitude to the aircraft. Methods and systems relate to a retraction spring for retracting the leg undercarriage system to a flight position and an electrical servo for retracting the leg undercarriage system to a flight position.
