Pro-Range 1608 40mm PC 3-Blade Propellers 4CW+4CCW - Clear Red

These propellers are designed for micro brushless motors with a 1mm shaft diameter, specifically the 0802, 1102, and 1103 motor sizes commonly used in tiny whoop and nano drone builds. Always ensure your motor's KV rating and battery voltage (typically 1S or 2S) are appropriate for the 0.8-inch pitch to avoid overloading.

A 0.8-inch pitch on a 40mm propeller provides an optimized balance between thrust and efficiency for low-KV micro motors. It generates sufficient lift for agile flight while minimizing current draw, which helps extend flight time and reduces heat buildup on small ESCs and 1S/2S battery packs.

Pro-Range propellers are precision-molded from polycarbonate for consistent weight distribution and are typically flight-ready. However, for optimal performance in high-RPM micro builds, it is recommended to perform a final dynamic balance check, as even minor imbalances can cause vibrations noticeable in FPV video feeds.

Yes, the 40mm diameter and tri-blade design are well-suited for many popular ducted cinewhoop frames designed for 2-inch or smaller props. The polycarbonate construction offers good durability against minor duct strikes. Ensure your frame's duct inner clearance exceeds 40mm to prevent binding.
