Use this comprehensive checklist to evaluate propeller options and ensure you select the optimal Gemfan product for your specific UAV platform and operational requirements.
Motor Compatibility: Verify shaft diameter matches propeller aperture (0.8mm–6mm options available)
Size and Pitch: Match propeller diameter and pitch to your frame class and flight style requirements
Material Selection: Choose PC for lightweight FPV, glass fiber nylon for durability, or carbon fiber for competition
Blade Count: 2-blade for efficiency, 3-blade for grip and control, 4-5 blade for smooth operation and thrust
Weight Consideration: Lighter props improve responsiveness; heavier props provide momentum and stability
Battery Configuration: Ensure propeller KV pairing matches your 4S or 6S battery setup for optimal efficiency
Mounting Type: Confirm single-hole, 3-hole, or M5 adapter compatibility with your motor bell housing
Quantity Planning: Order sufficient CW/CCW matched sets including spares for your fleet maintenance schedule

Find answers to the most common questions about selecting, ordering, and using Gemfan intelligent drone propellers for your UAV applications.
Match the propeller size to your motor's KV rating and frame class. Gemfan provides motor compatibility data for every propeller model—for example, 5-inch props like the 51433-3 pair with 2207-2306 motors, while micro 1.2-inch props suit 0802 motors. Check the product specification table for your specific motor model.
CW (clockwise) and CCW (counterclockwise) propellers are mirror-image blade designs that work in matched pairs on multi-rotor drones. Gemfan packages propellers in balanced sets—typically 4CW+4CCW for smaller props and 2CW+2CW for larger models—to ensure you have the correct rotation for each motor position.
PC (polycarbonate) is the standard choice for FPV racing due to its optimal balance of lightweight construction and impact resistance. For maximum performance, consider carbon fiber nylon options available in larger sizes (7"+). Glass fiber nylon offers enhanced durability for training and freestyle flying where crash resistance is prioritized.

Gemfan propellers are available in 0.8mm, 1mm, 1.5mm, 2mm, 5mm, and 6mm shaft apertures. Many models also support 3-hole mounting patterns and M5 adapter compatibility. Match the aperture to your motor shaft diameter—micro motors typically use 1mm, standard FPV motors use 5mm, and large fixed-wing motors may require 6mm.
Every Gemfan propeller undergoes multiple quality checkpoints: raw material inspection, precision molding verification, blade performance testing, dynamic balance testing, and final dimensional inspection.
