The field elevation where the flying took place was around 800 feet above mean sea level and we calculated a density altitude of around 2600 feet.
Upon closer inspection, once the aircraft was back on the ground, the Transition appears to be of high build quality with a lot of time and research having gone into the design of the aircraft.
ALTi Transition has a wing-span of 2.76 meters (or ~109 inches for those of you still in the dark ages of measurement standard), a length of 2.5 meters (~98 inches) and a height of 0.49 meters (~19 inches).
The Maximum Take-Off Weight (MTOW) of the aircraft is 15 kilograms (or roughly 33 pounds) and maximum payload weight of one kilogram (2.2 pounds).
Duran also mentioned that ALTi UAS will be offering all-electric versions of the Transition, although it is likely that with an all-electric version, horizontal flight times won't reach the 6 hour endurance mark that the liquid fuel powered version does.
Here are some of the selling points of the platform according to ALTi UAS:
"With a large payload bay area, open to fit and mount a huge range of cameras, sensors and other equipment, the system offers amazing flexibility and does not limit the operator or mission scope. With advanced sensors becoming smaller and lighter, the need for heavy payload capacity is no longer a concern.
As the needs and requirements of our clients vary greatly, along with the wide range of uses, payloads and sensors, we offer custom built and designed ground control systems per order to suit.
The airframe features incredibly efficient aerodynamic design, including dihedral, washout, winglets and quick release connectors for assembly.
From short range basic control systems to long range, vehicle mounted data telemetry, control, video link and payload control systems, as well as IP rated weatherproof hardware and flight cases.
Ultra bright, fully programmable navigation LED and strobe system, as well as a landing light underneath the airframe, with the ability to remotely turn the lighting on or off, as well as enable the landing light, special lighting features and more."
Electric VTOL Endurance: <10 Min
Fuel Fixed Wing Endurance: Over 6 Hours
Endurance based on actual real world flight tests."
