The BetaFPV Beta-45mm 3-blade propellers are lightweight props for micro drones and whoops with a 1.5 mm shaft. The page says they offer a balance of thrust, efficiency and stability.
The set weighs 1.63 g, has a 45 mm prop disk and is made of PC. The listed compatible quadcopter is the Aquila16 Brushless Quadcopter. The page showed it in stock.
Lightweight 3-blade design: with durable construction.
1.5 mm shaft hole: for secure mounting.
1.63 g per set: as listed.
45 mm prop disk: as listed.
Impact resistance: for a longer lifespan.
Indoor and outdoor flying: per the listing.
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 the Aquila16 Brushless Quadcopter as compatible. Check that other drones have a 1.5 mm shaft and suit a 45 mm prop before you buy.
Sort the four props into CW and CCW before you fit them.
