A few months ago, I tested the BetaFPV Pavo 30, a very capable CineWhoop. Unfortunately, I needed to replace the flight controller and two of the motors due to an accident. While the stock motors were 3400KV, I found as a replacement only these BetaFPV 1506 3000KV ones.
Brushless motors in the drone world are marked with a 4- digit number: AABB, the first two digits (“AA” part) refer to the stator width and “YY” to stator height. The torque depends on those two parameters- the wider and higher it is, the motor is more capable of making a higher torque (more power/trust). The “KV” parameter represents the number of revolutions a motor makes upon applying 1 Volt current without any load attached to the motor. For example, BetaFPV 1506 has a KV rating of 3000. It means that the motor spins 3000 rpm at the application of 1V without load (propeller installed). With a 3S LIPO the 3000KV could feel underpowered, but…
