Frequently Asked Questions:

Q1. What is the main purpose of "ducted" propellers like the GEMFAN D90, especially for cinewhoops?

Ans. The main purpose of "ducted" propellers like the GEMFAN D90 is to improve safety by enclosing the spinning blades within prop guards, and to enhance aerodynamic efficiency for smoother, more stable flight. For cinewhoops, this design allows for safe indoor flying near people or objects, minimizes "prop wash" in video footage, and can slightly increase thrust by directing airflow, making them perfect for cinematic FPV.

Q2. What does "M5" in the GEMFAN D90 specification refer to?

Ans. "M5" in the GEMFAN D90 specification refers to the mounting hole size on the propeller hub. It means the propeller is designed to fit directly onto brushless motors that have a 5mm diameter shaft, secured with an M5 lock nut. This direct mounting method is common for cinewhoop motors and ensures a secure, vibration-free connection.

Q3. Will these GEMFAN D90 propellers fit any 3-inch or 3.5-inch FPV drone?

Ans. While the D90 propeller is well-suited for 3-inch or 3.5-inch cinewhoop drones, it's crucial that your drone frame is specifically designed to accommodate ducted propellers of 90mm diameter. Standard open-prop FPV frames typically cannot fit ducted props. Additionally, ensure your motors have 5mm shafts (M5 mount) for proper fitment. Always verify your frame and motor specifications for compatibility.
