Quick question hopefully someone can help with. When using APM 2.6 with an airspeed sensor and on an airplane is there anyway to just set the airspeed when flying in auto mode? For instance just say fly 30 mph. I understand that there is a cruise throttle percentage setting, but is there anyway to just tell the plane to fly this speed? Also, on mission planner what does change speed do and where do you set the original airspeed?
