Why this product helps Versatile fit: Six adapters and a 9.4 mm hub suit many electric motor shafts and mounting setups, reducing the need for custom parts. Match flight goals: Multiple size and pitch options let you choose higher thrust or higher speed according to aircraft type and mission. Replacement and maintenance: Sturdy nylon resists minor impacts and is a reliable choice for routine prop replacement. Practical use scenarios worn props on an electric trainer plane with an 8x4 or 8x6 to restore smooth handling. Fit a 9x6 prop on a light multirotor to experiment with increased lift for slowspeed stable flight and aerial filming. Test different pitch options, such as 10x5 versus 10x7 on a sport plane, to balance climb rate and speed. What you get Gray nylon electric propeller(s) in the selected size(s) with six hub adapters for easy installation and compatibility across common RC aircraft and multirotor setups.
