2–4 Inch FPV Propellers

This category covers FPV propellers in popular sizes from 2 to 4 inches, providing an ideal solution for a wide range of light and agile drones. They are larger and often more aggressive than TinyWhoop props, but lighter and less power-hungry than standard 5-inch propellers.

2-4 inch propellers are used in builds such as:

• Toothpick class drones: Ultralight, agile machines (most often 2.5 - 4 inches).
• Lightweight 3-4 inch Freestyle drones: Smaller versions of popular 5-inch quads, ideal for tight spots.
• Small Cinewhoops: Stable platforms for recording (mainly 2.5 - 3.5 inches), often with ducts.
• Larger Micro Drones: Custom builds requiring propellers in this size range.

They feature a variety of mounting options – from the popular T-mount (2 M2 screws), through press-fit holes (1.5mm, 2mm), to the standard 5mm bore on some 4-inch models. The most common versions have 2 or 3 blades. We offer proven propellers from market leaders like Gemfan and HQProp.

Choosing propellers in the 2-4 inch range requires considering the specifics of lightweight drones, where every gram counts and precise matching to the powertrain is essential.

• Size (2", 2.5", 3", 3.5", 4"): Choose the size recommended for your frame and motors. 2-2.5 inches fit the smallest Toothpicks. 3 inches is a very popular size for lightweight freestyle drones and many cinewhoops. 4 inches work well on larger Toothpicks and ultralight freestyle builds.
• Mounting Type: This is a crucial parameter! Double-check what mounting your motors require: T-mount (two M2 screws, very popular), press-fit onto the shaft (1.5mm or 2mm diameter), or the standard 5mm bore (less common, mainly on 4-inch). The wrong choice will make mounting impossible.
• Pitch: Similar principles as larger props, but scaled down. Higher pitch provides more "punch" and speed but consumes more power. Lower pitch offers better efficiency and smoothness. Match it to your motor power (KV) and battery voltage (2S, 3S, 4S).
• Number of Blades (mainly 2 or 3): 3-blade props are often preferred in freestyle and cinematic for smoothness and control. 2-blade props can be slightly more efficient and lighter, valued in Toothpick builds focused on maximum agility.
• Weight and Durability: In lightweight drones, propeller weight significantly impacts response and flight time. Find a balance between low weight and sufficient durability for your typical crashes.

Manufacturers like Gemfan and HQProp offer many different models in this range, allowing for fine-tuning of flight characteristics.
