The X9 3411 is a 34x11 inch folding CW/CCW propeller engineered for agricultural drones. The page describes a blend of carbon fiber and nylon alloy, a folding design that reduces drag and noise, and precision dynamic balancing.
The specification list gives a maximum thrust of 27 kg per axis (53.6V, sea level), a recommended takeoff weight of 11 to 13 kg per axis, a 6 to 14S LiPo battery, a working temperature of -20°C to 50°C, an IPX6 waterproof rating and a 100KV motor rating. The page showed only 8 left in stock at Rs 3,619.
34x11 inch folding design: reduces drag and noise.
Carbon fiber and nylon alloy: durable, light and resilient.
Max thrust 27 kg per axis: at 53.6V and sea level.
6 to 14S LiPo: the listed battery range.
IPX6 waterproof rating: as listed.
Precision dynamic balancing: for smoother control.
A drone propeller converts motor torque into thrust. Each blade is an aerofoil: as the motor spins the prop, the blades push air downward and the reaction force lifts the aircraft. Diameter and pitch set how the prop behaves. A larger diameter moves more air and suits efficient, lower-RPM flight, while a higher pitch moves the aircraft forward faster per revolution but demands more current from the motor.
Multirotors use pairs of props that spin in opposite directions. Clockwise (CW) and counter-clockwise (CCW) props cancel out the torque reaction so the aircraft does not spin, and the flight controller changes individual motor speeds to steer. Always fit each prop on the motor that turns the matching direction, and check your flight controller motor-direction settings before the first flight.
Fit and balance matter. The hub hole or shaft size must match your motor shaft, and the prop should sit flat and tight with the retaining nut fully secured. Check every blade for chips, cracks and bends before each flight, because a damaged prop causes vibration that shows up as jello in the video and extra heat in the motor. Replace props after a hard crash instead of flying on a damaged set.
Keep a few spare sets in your kit. Props are the part most likely to break in a crash, and swapping a damaged one takes only a minute. When you replace a prop, replace it with the same size, pitch and blade count as the rest of the set so that all motors produce matching thrust.

The page lists 100KV motors, a 6 to 14S battery and 11 to 13 kg takeoff weight per axis, so it is meant for large agricultural platforms. Check your motor mount and hub before you buy.
Folding props should be checked for smooth folding action and locked open before each flight.
