Gemfan 1608-3 40mm Tri-Blade 1.0mm Shaft Propellers - (4CW+4CCW) - Choose Color

Perfect

Just right for my Air 75

Smaller shafts

These only fit the 1mm shaft so they're great for 0702 and most 0802

Great high performance props designed for 25,000kv motors!

These props will give you more power & speed at the cost of flight time... These 3-blade props give more speed but less control indoors, I prefer the 4-blade props to fly in my small home...
