Product overview
The T-MOTOR MN701-S KV135 is a brushless UAV propulsion motor in the Navigator range, intended for multirotor, VTOL and fixed-wing aircraft. Its civilian applications include aerial photography, cargo transport, tethered operations, mapping and inspection. The KV135 variant supports 6–12S LiPo batteries and recommended propeller diameters of 24–26 inches, with FLAME 60A 12S and FLAME 80A 12S V2.0 ESCs recommended for integration. It measures 79.2 mm in diameter by 37.4 mm and weighs 350 g including its cable. Its specified peak current is 42 A and maximum power is 1900 W, both rated for 180-second operation.
The motor uses a 24N28P configuration and centrifugal cooling, with IP45 protection, anti-corrosion features and high-temperature-resistant winding materials. KV135 bench results record 9733 g of thrust with a T-MOTOR G26*8.5 propeller at 100% throttle, 46.64 V, 39.50 A and 1842 W. That configuration has a “HOT” temperature designation at 34.5°C ambient temperature. With a T-MOTOR P24*7.2 propeller, the full-throttle result is 8011 g at 47.03 V and 1345 W, with a surface temperature of 70°C at the same ambient temperature. Temperature readings correspond to ten minutes at 100% throttle. These bench-test figures are for reference only; comparison with other motor types is not recommended.
