Pro-Range 1636 PC 4-Blade 40mm Propellers 4CW+4CCW - Clear Purple

These propellers are specifically engineered for 1103 to 1105KV brushless motors. The 1mm single-hole mounting pattern is standard for this motor size class. Using them on significantly larger or smaller motors may result in inefficient performance or potential damage.

Yes, the 4-blade design and 3.6-inch pitch provide a good balance. The quad blades offer increased disc loading for punchy thrust and stability in corners (beneficial for racing), while the polycarbonate construction provides the durability needed for freestyle crashes. They are a versatile choice for 3-inch micro builds.

Pro-Range propellers are injection-molded and typically come from the factory with good balance, reducing the need for immediate manual balancing for most pilots. However, for the smoothest possible flight performance, especially in high-RPM applications, fine-tuning with a propeller balancer is always recommended.
