FPV Propeller Guide
Props are the part you replace most often. This guide helps you understand specs, materials, and how to pick the right prop — so you order with confidence, not guesswork.
What do propeller numbers mean?
A prop name like "5.1x4.5x3" tells you everything you need to know: 5.1" diameter, 4.5" pitch, 3 blades. Here's what each spec means and why it matters:
HQProp DP 5.1X3.6X3 PC Propeller
= 5.1" diameter, 3.6" pitch, 3 blades, Polycarbonate material
The prop's total span in inches. A 5" prop fits a 5" frame. Larger diameter = more thrust but slower response. This is determined by your frame — don't guess it, match it.
How far the prop moves forward per rotation, in inches. Higher pitch (4.5"+) = more speed, more power draw, more aggressive feel. Lower pitch (3.5"–4.0") = smoother, quieter, more efficient.
2-blade (bi-blade), 3-blade (tri-blade), or 4-blade. More blades = more grip and smoother feel, but lower efficiency. Tri-blade is the most popular all-rounder for 5" quads.
The motor shaft hole diameter. Most 5" motors use M5 (5mm). Micro and Whoop motors use 1.5mm. Every product page on PropShop shows compatible shaft sizes — check before ordering.
Materials: PC vs Nylon vs Glass Fiber
Flexible and crash-resistant. Bends on impact instead of snapping. Less precise feel, but lasts longer. Best for freestyle and learning.
Stiffer than PC, good balance of performance and durability. Breaks cleaner on hard impacts. The standard choice for most pilots.
Very stiff, very responsive. Best thrust performance, but shatters on impact. Popular for racing where every gram and millisecond counts.
Which prop for which flying style?
Tri-blade, medium-high pitch (e.g. 5.1x4.3x3). Durable material like PC. You want grip for tricks, power loops, and crash resistance above all.
Bi-blade or tri-blade, higher pitch (e.g. 5.1x4.8x3). Glass fiber nylon for maximum response. Every gram of weight matters at race pace.
Bi-blade, lower pitch (e.g. 5.0x3.0x2). Smooth, efficient thrust for stable footage and longer flight times. Quieter props reduce vibrations in video.
2"–3.5" diameter, often 4-blade for whoops. Lightweight and cheap to replace. Check your motor's recommended prop size — it's usually printed on the motor bell.
How many props do I need?
A quad uses 4 propellers — 2 clockwise (CW) and 2 counter-clockwise (CCW). Most sets include all 4. We recommend keeping at least one spare set, because crashes happen.
