Overview
T-Motor MN4112 KV320/KV420 is a UAV motor designed for multi-rotors, VTOL, and fixed-wing platforms. It is positioned for general-use applications such as aerial photography and supports configurations for both fixed-wing and multi-rotor working conditions (U7 prop adapter available separately).
Key Features
- For multi-rotors, VTOL and fixed wings
- 5% more efficient on 1kg-2.5kg
- 5% more thrust on 100% throttle
- Heat flux increases by 18%
- Reasonable airflow channel design for cooling and endurance
- High-performance iron core material, high slot rate, and reduced heat generation (for long-lasting flight)
- Efficiency goes up to 8g/W on 60% throttle
- Fast response (12N14P configuration; high winding coefficient and small harmonic wave stated for “carefree flight”)

Details

The T-Motor MN4116 KV450 brushless outrunner motor suits multirotor, VTOL, and fixed-wing aircraft builds.

T-Motor brushless motor setups are illustrated for both fixed-wing and multirotor builds with a mounted propeller.

The vented airflow channel design helps dissipate heat to support longer endurance during flight.

The T-Motor design notes a 12N14P configuration for the motor’s internal layout.
