The 2805 140KV gimbal brushless motor is described as precision power for smooth cinematic shots. It is engineered for precision and performance and is meant to help capture smooth, professional-quality footage.
The listing says the 140KV rating is ideal for powering 3-axis camera gimbals for fluid motion and stability, and that the motor is compatible with the GoPro Hero 3/3+.
It is compact and lightweight and is described as durable enough for the rigours of outdoor filming.
140KV power: for 3-axis camera gimbals, fluid motion and stability.
GoPro Hero 3/3+ compatible: made for popular action cameras.
Compact and lightweight: no unnecessary bulk.
Durable construction: built to withstand outdoor filming.
A brushless gimbal keeps a camera pointing steadily while the aircraft moves. A controller board reads an inertial sensor mounted on the camera and drives brushless motors on each axis to cancel out any rotation. Because gimbal motors are wound for smooth, low-speed torque and not for speed, they hold the camera steady with very little vibration and noise.
Gimbal quality depends on the whole system: balance, damping and controller tuning matter as much as the motors themselves. A camera that is not balanced on its axes forces the motors to work harder, heats them up and can cause jitter, so balance the camera carefully before you tune anything.
Also isolate the gimbal from airframe vibration with soft damping mounts, keep motor wires away from the sensor and never power the gimbal with the camera locked or blocked, as the motors can overheat when they cannot move.

The listing gives a KV rating of 140, a shaft diameter of 5.4mm and a size of 34.5 x 14mm. It does not list a weight, a cable length or a package list, so confirm these with the seller if your gimbal design depends on them.
Match the motor to the controller's current rating and to the weight of your camera.
