It supports quadcopters, hexacopters, and octocopters using a 400Hz frequency and the Ronin-MX. An impressive feature is how a hexacopter or octocopter can land safely using the A3 Controller in the event of propulsion system failure due to a fault-tolerant control system. It also offers DJI Smart Battery Protection and Motor Overload Protection.
The A3 operates best with the 35 to 125 LiPo or DJI Smart Battery.
