Overview
About T-Motor Navigator MN4014 400KV.
The T-Motor Navigator MN4014 400KV is a high-thrust 4014-class brushless motor built for medium-to-large multirotors and heavy-lift UAV platforms. Its large 40mm-diameter, 14mm-tall stator in an 18N24P configuration carries a lot of copper and magnet material, and the low 400KV winding is designed to turn big 15-18 inch propellers at efficient RPM on 4S-8S LiPo — the formula for lifting heavy payloads such as cinema cameras and survey sensors with stability.
T-Motor builds the MN4014 with silicon-steel laminations, a 4mm shaft and precision construction for smooth, vibration-free running under load. It draws about 1.3A idle at 10V, has roughly 67mΩ internal resistance, and is rated for 30A maximum continuous current (180s) at up to 900W, so it delivers substantial thrust while remaining efficient enough for endurance work on larger frames.
This motor targets builders of heavy-lift hexacopters and octocopters, professional cinematography rigs, agricultural and survey drones, and DJI S800-class platforms. Running a T-MOTOR 17x5.8 propeller each MN4014 produces up to around 3.3kg of thrust, giving the high payload margin needed for gimbal-stabilised cameras, LiDAR pods and other demanding professional payloads.
Key features
Why it stands out.
Low 400KV winding turns big props efficiently on 4-8S for stable lifting of cameras and survey payloads.
Up to ~3.3kg thrust per motor with a 17x5.8 prop gives generous payload margin on multirotor rigs.
30A continuous / 900W rating combines strong power with the efficiency needed for endurance missions.
Smooth, vibration-free running supports gimbal-stabilised cinematography and clean sensor data.

Buying guide
How to choose.
Choose the MN4014 400KV when you need to lift real payloads — cinema cameras, LiDAR, spraying gear — on a medium-to-large multirotor. The low 400KV and big stator are made to turn 17-18 inch props efficiently; do not pair it with small props expecting speed. Buy a balanced set sized to your frame (6 for a hex, 8 for an octo) and budget thrust so hover sits near 50% throttle for efficiency and safety margin.
Match the ESC above the 30A continuous rating — a 40A-class or higher ESC per motor gives headroom for gusts and payload swings. Pick cell count for your thrust/efficiency target: 6S is a common balance, while 8S raises the ceiling for the heaviest lifts. Use the recommended T-MOTOR 17x5.8 (or similar large CF) propeller and confirm prop-hub compatibility before ordering.
For India buyers, confirm the exact KV (the MN4014 is sold in 330 and 400KV among others), whether you are buying singles or a matched set, and that the stock is genuine T-Motor for guaranteed balance and bearing quality on payload-critical builds. Plan your power system (battery C-rating, wiring gauge, ESC) around the full set's combined current draw.
FAQ
Common questions.
What is the MN4014 400KV designed to lift?
It is a heavy-lift motor for medium-to-large multirotors carrying real payloads — cinema cameras, LiDAR, survey sensors or spraying gear. The big 4014 stator and 400KV winding turn large 17-18 inch props efficiently to produce high, stable thrust.
How much thrust does each motor make?
With a T-MOTOR 17x5.8 propeller each MN4014 produces up to around 3.3kg of thrust near full throttle. For safe, efficient flight, size your craft so hover sits near half throttle, consulting T-Motor's thrust data for your prop and cells.
Which battery and propeller should I use?
T-Motor rates it for 4-8S LiPo with a recommended 17x5.8-inch propeller. 6S is a common balance of efficiency and thrust; 8S raises the ceiling for the heaviest payloads. Always match prop and cells to your target all-up weight.
What ESC rating is required?
The motor is rated 30A maximum continuous, so use a 40A-class or higher ESC per motor for headroom against gusts and payload shifts. Ensure your battery C-rating and wiring can supply the full set's combined current.
How much does the motor weigh?
Each MN4014 weighs about 150g without cables, or roughly 171g including leads. That is light for its thrust class and helps keep heavy-lift rigs efficient when scaled across six or eight motors.
Does it come in other KV options?
Yes. T-Motor offers the MN4014 in 330KV and 400KV (among others). The 400KV suits 17-18 inch props on 4-8S; lower-KV versions favour even larger props and lower-RPM, higher-efficiency heavy-lift configurations.
