This was a challenging project, but one we had a lot of fun with. The clients requirements were to lift a 23lb payload on the end of a suspended tether while maintaining an all up weight that was under 55lbs. We chose a 1200mm Gryphon Dynamics chassis to make an X8 high voltage lifter. The 48v system allows for plenty of power and punch when needed, yet highly efficient low amp draw at hover. We chose the A3 Pro for this system because precision hover accuracy is a must. This bird flies incredibly well and we were admittedly a little bit sad to send her off to her new home. But we're told there is lots of open space for her to fly around, which makes us feel better.
