Best on Test

HQProp Duct-T63MMX3 3-Blade Propeller - Light Grey (Set of 4)

2.5" Cine Whoop props need to pack a lot of thrust into a small space. This bullnose design from HQ will give the right amount of performance for lifting a naked Go Pro and larger battery for longer flight times. Can be used with or without ducts.

EMAX Avia TH1609 3" 2-Blade Propeller (Set of 4)

Emax make some great props for smaller quads. These are my favourite for 3S toothpicks, plenty of thrust with good efficiency and well matched to a 1204/1303 size motor.

HQProp T3.5X2.5X3 Propeller (Set of 4)

HQ make fantastic props that often come out top in my testing across many different sizes. This is a great choice for 3.5" freestyle with minimal propwash and good efficiency.

Gemfan 1219-3 31mm 3-Blade Whoop Propeller (1mm Shaft - Set of 8)

These props from Gemfan are perfect for 65mm tiny whoops. 3-blades gives a good balance of power and efficiency. With Whoops it's important to check shaft diameter on props and motors!

EMAX AVAN Scimitar 3.5x2.8x3 Propeller (Set of 4) - Red

This is the prop I recommend for the AOS 3.5. It is well matched to a 1504/1505 size motor with minimal propwash and plenty of top end thrust and power.

HQProp 40MM 3-Blade Micro Whoop Propeller (1.5mm Shaft - Set of 4)

HQ produce some lovely props and they frequently come out top in my performance testing. These props are perfect for 75mm Whoops and well matched to a 1002 size motor.
