These are simply triple triplocopters, i.e. the equivalent of 9 helicopters stuck together. Super-fast and powerful, but can only be flown by the very top students at flight school. James Hogsbottom was the first person to ever successfully land one. There have been three documented triplo-triplocopter crashes to date.
Triplo-triplocopters often get used for heavy-duty tasks, such as lifting of buildings.
They are manufactured by G & J Tarrow Siblings Inc.
