Pro-Range D75 Ducted PC 3-Blade 75mm Propellers 2CW+2CCW - Green

The Pro-Range D75 propellers are designed for brushless motors in the 1408 to 1808 size range, commonly used in 3-inch CineWhoop builds. They feature dual mounting holes (1.5mm and M5 threads) to accommodate different motor shaft configurations within this size bracket. Always verify your specific motor's shaft diameter and threading before installation.

These propellers are optimized for typical 3-inch drone power systems, which commonly use 3S or 4S LiPo batteries. While they can handle 4S, using them on aggressive 6S setups with high-KV motors may exceed their design limits, leading to excessive flex, vibration, or failure. For 6S applications, ensure your motor and ESC combination is well within safe amp draw limits with this pitch and diameter.

Pro-Range propellers are manufactured to good tolerances and are typically ready to use out of the package for most recreational and cinematic flying. However, for optimal performance, especially in high-RPM applications or for the smoothest possible video footage, a final dynamic balance check and minor adjustment with a propeller balancer is always recommended.
