EMAX AVAN Propellers Guide: 2 to 6 Inch, Which to Buy?
Every EMAX AVAN propeller is designed around a specific motor, and that single fact decides which one you should buy. For 5-inch freestyle quads running 2206–2306 motors around 2400KV, the AVAN Flow 5×4.3×3 is the all-rounder. If your build uses an RS2306 or RS2205 and you want maximum top speed, the two-blade AVAN-S is the match; the three-blade AVAN-R adds grip for aggressive racing. Cruising builds should pick the AVAN Long Range 6×3.8×2, optimized for low current at 50 mph on a 1900KV 2207. And for whoops and micros, the family scales down cleanly: Blur for 2-inch, Rush for 2.5-inch, Babyhawk for 2.3-inch and Mini for 3-inch. This guide compares every AVAN prop we stock with the geometry, weight and motor matching printed on each product page.
Why Do AVAN Propellers Feel Different to Fly?
EMAX designs AVAN props with custom CFD software using a Vortex Lattice Method, then optimizes each design against the Betz condition for a defined point: diameter, blade count, rpm and required thrust. The result is a true constant pitch along the blade — most props vary pitch from root to tip — which produces the linear throttle response the whole family is known for. Blade profiles are optimized along the length to maximize lift, and a special polycarbonate blend with a thick root keeps them durable. Most of the mass sits near the hub, so the moment of inertia stays low and the prop responds quickly to throttle changes. The 5-inch models also carry an exclusive hub locking design that matches RS2306 and RS2205 motor shafts to reduce prop loosening mid-flight.
Which AVAN Prop Matches Your Motor?
Motor matching is the whole purchase decision, so start from your motor — not from the prop you like the look of. The table below lists every current AVAN model with the geometry and matched motor published on its product page. Prices range from $2.29 for a 2-inch set to $10.01 for a five-pack of 5-inch props, so experimentation is cheap; burning a motor because the prop load was wrong is not.

AVAN-S vs AVAN-R vs Flow: Which 5-Inch Prop?
All three 5-inch models target the same 22xx–23xx motor class, so the choice is about blade count and flying style. The AVAN-S is the two-blade speed option: its design brief pairs it directly with the RS2306 and RS2205, the hub lock keeps it tight through high-rpm runs, and fewer blades mean less drag when you are chasing straight-line speed. The AVAN-R moves to three blades for racing lines — more blade area gives bite in corners at the cost of a little efficiency, and the bulk 2CW+2CCW pack at $5.84 makes replacements cheap. The AVAN Flow sits between them as the freestyle pick: 4.3 grams with a moment of inertia of 13.4 g·cm², tuned for 2206, 2207 and 2306 motors around 2400KV. If you fly a mix of cruising, punching and technical lines, start here; our EMAX Hawk 5 guide covers a BNF that ships on exactly this prop.
Is the AVAN Long Range 6×3.8×2 Worth Trying on a 7-Inch Build?
The Long Range prop is the most specialized model in the family, and its design point is unusually specific: EMAX optimized it to operate at 50 mph with low current consumption at that speed, maximizing distance per charge. Geometry is 6×3.8×2 — a low pitch for a 6-inch prop — weighing 4.6 grams with a moment of inertia of 14.4 g·cm². The matched motor is the LS2207 1900KV on 4S, with aggressive flying possible on 5S. A thick chord at the blade root raises the blade’s natural frequency, which minimizes vibrations and delivers jello-free footage on a cruising quad. If you are building a long-range rig around a 1900KV 2207-class motor, this prop belongs on the shortlist; the Hawk long-range BNF guide covers ready-to-fly alternatives in the same mission profile.
Blur, Rush, Babyhawk or Mini: Picking Micro Props by Frame Size
The micro lineup scales by wheelbase, and each prop states its motor match explicitly. The AVAN Blur 2×1.9×3 is the lightest at 1.1 grams (0.77 g·cm²), made for the Babyhawk Race 2-inch on a 1106 6000KV motor at 3S or 4S. Step up to the AVAN Rush 2.5×1.9×3 for the 2.5-inch conversion kit — 1.4 grams, matched to a 1106 4500KV on 4S or the 6000KV on 3S. The AVAN Babyhawk 2.3×2.7×3 carries the deepest pitch of the group at 2.7 inches and pairs with the original 1104 5250KV motor on 2S–3S; its 5mm hole pattern also fits other micro motors, and EMAX suggests trying it on 1106 6000KV motors for extra thrust. The AVAN Mini 3×2.4×3 closes the range at 3 inches for 1106 4500KV builds on 3S–4S. For outright speed in a 2-inch footprint, the AVAN Micro quad-blade claims over 70 mph with 11xx motors from 4500–6500KV on 2S–4S packs.
When Should You Swap to the AVAN TH Turtlemode Prop?
The AVAN TH Turtlemode is a niche tool for Tinyhawk-class whoops: a 4-blade prop, 40mm in diameter with a 31mm pitch, weighing just 0.63 grams. It generates more thrust at lower rpm than the stock Tinyhawk prop, which is exactly what the turtle-mode flip needs — reverse thrust only works if the props can bite from a standstill. The trade is explicit on the product page: slightly less flight time than the stock prop, in exchange for more control and aggressive flying with turtlemode capability. If you never use turtle mode, stay on the stock props; if you flip over in grass every session, this $4.60 set pays for itself quickly.
Frequently Asked Questions
Can I run AVAN props on motors other than the ones listed?
Yes, with care. The listed motors are design matches, not exclusivity locks — the AVAN Babyhawk, for example, carries a 5mm hole pattern specifically so it can mount other micro motors. Stay within the same stator class and KV window as the match, and expect performance to drift the further you move from it. EMAX explicitly does not recommend cloned props, citing poor performance.
Why does a constant pitch matter on a propeller?
A true constant pitch along the blade means every section of the prop works at the same effective angle across the throttle band. That is what produces the linear throttle response EMAX markets across the AVAN line — the quad feels predictable at mid-stick instead of stepping through power bands. EMAX achieves this by optimizing the blade angle distribution (Beta) in CFD for a specific design point rather than copying a generic profile.
What does moment of inertia tell me about a prop?
It measures how much of the prop’s mass sits away from the hub. Lower numbers mean quicker spool-up and sharper throttle response because the motor accelerates less rotating mass. Compare within the family: the Blur sits at 0.77 g·cm² while the Long Range reaches 14.4 g·cm² — the micro prop snaps, the cruiser needs a beat to respond, and both behaviors suit their missions.
Are AVAN props durable enough for whoops?
The micro range is engineered for it: a special polycarbonate blend that EMAX describes as tough and ductile, thick blade roots, and an injection mold process tuned to reduce bubbles and keep balance. The Babyhawk prop’s large blade chord is called out specifically for durability. At $2.29–$6.91 per pack, running spares costs less than a single 5-inch prop.
Do I need CW and CCW props in a pair?
Yes — quadcopters spin two motors clockwise and two counter-clockwise, so every pack is sold as 2CW+2CCW or in bulk multiples of that ratio (the AVAN-S five-pack is 10 CW plus 10 CCW). Mixing rotation directions on one axis would make the quad unflyable, so check the split before you mount.
The Bottom Line
AVAN is not a generic prop line — it is a family of motor-specific designs, and that is its advantage. Match the Flow to a 2400KV 5-inch freestyle build, the S or R to RS2306/RS2205 racers, the Long Range 6×3.8×2 to a 1900KV 2207 cruiser, and the Blur/Rush/Babyhawk/Mini trio to the frame size you actually fly. Keep a Turtlemode set in the whoop bag if you fly around grass. For full context on sizes, pitch and materials, our FPV propeller guide and the EMAX Buzz 245mm guide cover the wider picture. Pick your match, order two packs, and get back in the air.
