7-Inch Propellers
7-Inch Propellers
30 products
7-inch propellers are the long-range FPV size: big enough to cruise efficiently on a 6S pack, small enough for a frame that still fits a backpack. This page collects every 7-inch prop in our Propellers range — tri-blade and bi-blade props for 7-inch quads, folding props, and 7-inch electric props for fixed-wing models. Choose by pitch and blade count for a quad, or by diameter × pitch for a plane, and check how many props a pack contains.
How to choose a 7-inch prop
- Reading the name: 7035 means 7.0-inch diameter and 3.5-inch pitch. HQProp writes the same thing as 7x3.5x3 — diameter, pitch, blade count.
- Pitch: 3.5 to 4 is the efficient cruising range. 4.3 to 5 gives more top speed and thrust, and draws more current.
- Blade count: bi-blades are the most efficient for range. Tri-blades give more grip and smoother handling with a camera on board.
- Material: polycarbonate props bend and survive crashes; glass-fibre nylon props are stiffer, which keeps a 7-inch blade from fluttering under load.
- Folding props: the blades fold back for transport and open under rotation — useful on folding long-range frames.
- Fixed-wing props such as 7x5 or 7x6 are made for a plane's single motor and use a different hub from quad props.

Compatibility
7-inch quad props fit an M5 motor shaft and suit 2806.5 to 2810 stators of roughly 1100–1350KV on 6S. They need a frame built for 7-inch props; they will not clear the arms of a 5-inch or most 6-inch frames. Quad props are sold as CW and CCW — a quad needs two of each, so check whether the listing is a pair or a set of four.
Frequently asked questions
- What do the numbers on a 7-inch prop mean?
- The first two digits are the diameter and the last two the pitch: 7040 is a 7.0-inch prop with 4.0-inch pitch. A third number, as in 7x4x3, is the blade count.
- Which motors run 7-inch props?
- 2806.5 to 2810 stator motors at roughly 1100–1350KV on 6S are the usual pairing. Smaller 2207 or 2306 motors overheat on a 7-inch prop.
- Bi-blade or tri-blade for long range?
- Bi-blades are more efficient and give the longest flight time. Tri-blades give more thrust and steadier handling, which suits heavier builds and filming.
