Product overview
The T-MOTOR 705-X is a modular propulsion arm set for industrial and heavy-lift multirotor UAVs. Its supplied configuration combines an MN705-S KV125 brushless motor with an Alpha 80A FOC ESC for integration into an aircraft. The arm measures 143*90.6*75.2mm and weighs 730g including wire, with 600mm of exposed wiring. An included adapter ring accommodates 30mm and 25mm tubes, providing two tube-size options for mechanical installation. A built-in LED supports visibility during low-light UAV operation.
The propulsion system uses a 12S LiPo electrical configuration, with an idle current of 1.5A at 24V and internal resistance of 63mΩ. Its 45A peak-current rating applies for 180s, and its 1900W maximum-power rating applies for 180S. The recommended MF2614 carbon fiber folding propeller is optional and sold separately, so it requires separate procurement from the motor and ESC arm set. Additional propeller options for the 705-X configuration are G26*8.5 and FA26.2*8.5.
