RAYI manufactures electric fixed wing propellers engineered specifically for battery-powered cruise motors, not adapted from multirotor or gasoline-engine blade geometry. Every blade in this line is molded from aerospace-grade carbon fiber with a lightweight core structure, independently benchmarked more efficient than comparable propellers on the market — a direct contributor to extended flight time on battery-limited platforms.
If your procurement decision is still open between an electric or gasoline cruise motor for a new fixed-wing or VTOL airframe, this page walks through the actual trade-offs before you commit to either propeller line.
An electric fixed wing propeller is not a smaller version of a gasoline cruise blade — it's a different design problem, because electric cruise motors typically run at different RPM curves, lower vibration loads, and tighter weight budgets than combustion engines.
Electric cruise propulsion advantages:
Significantly quieter operation, important for surveying and inspection missions over populated areas
Lower maintenance burden — no fuel system, spark, or combustion byproducts to manage in the field
Precise throttle and RPM control paired with modern ESCs, including propeller stop-position control on VTOL platforms during vertical transition phases
Lower total propulsion weight when paired with a lightweight carbon fiber blade, which is where the airframe's endurance budget is actually won or lost
Where gasoline still wins: raw endurance on long-range missions where battery energy density remains the limiting factor, and total mission weight allows for fuel rather than battery mass.
For teams already committed to an electric or hybrid-electric cruise motor, propeller weight and aerodynamic efficiency compound directly into flight time — which is the core reason electric fixed wing propeller buyers prioritize a purpose-built blade over a repurposed multirotor prop.
Purpose-built cruise geometry. Blade profile and pitch are optimized for sustained cruise RPM on electric motors, not adapted from hover-optimized multirotor blades — the airfoil and pitch distribution are designed around continuous forward-flight loading.
Weight-driven construction. Carbon fiber layup with a lightweight core delivers roughly weight reduction versus comparable market propellers, directly extending flight time on battery-powered platforms where every gram trades against endurance.
VTOL-compatible sizing. Diameters spanning 15"–23" and beyond support both dedicated fixed-wing cruise motors and hybrid VTOL platforms transitioning between vertical and forward flight.
ISO 9001-certified production. Consistent blade-to-blade balance and dimensional accuracy across production batches, verified for global drone applications rather than single-sample quality.
OEM/ODM and bulk supply. Custom pitch, custom hub bore, and private-label packaging for teams integrating an electric fixed wing propeller into a branded propulsion system.
Full propulsion-system support. Matched motors and ESCs available alongside the propeller for teams validating a complete electric cruise stack rather than sourcing parts from multiple suppliers.
This is what separates a real electric fixed wing propeller manufacturer from a reseller quoting a generic catalog: we can explain why a 20x13 outperforms a 19x12 on your specific cruise motor's KV and voltage combination, backed by tested data.
For electric fixed-wing and VTOL cruise applications, pitch selection tracks target cruise speed more directly than it does for gasoline platforms, since electric motors typically operate across a narrower, more predictable RPM band.
| Mission Priority | Pitch Ratio Guidance | Typical Diameter |
| Long-endurance mapping / survey | Medium pitch for balanced climb and cruise efficiency | 15"–19" |
| VTOL hybrid transition platforms | Medium-high pitch, compatible with propeller stop-position control | 19"–21" |
| High-speed cruise / relay missions | High pitch ratio for maximum forward speed per RPM | 20"–23" |
If you already have a target diameter x pitch from your motor manufacturer's datasheet, jump directly to that spec in the reference table below rather than reading through the full guide.
Browse by exact diameter x pitch. Each model is sized and pitched specifically for electric cruise motor operation; custom sizes outside this table are available through our OEM program.
What makes an electric fixed wing propeller different from a gasoline cruise propeller?
Electric cruise motors typically run at different RPM curves and lower vibration loads than combustion engines, and total system weight is far more sensitive to propeller mass since there's no fuel to offset it. An electric fixed wing propeller is designed around these constraints — lighter construction, pitch tuned for electric motor RPM bands, and blade profiles optimized for continuous cruise rather than combustion-engine torque delivery.
Can these propellers be used on VTOL platforms during vertical takeoff and landing transitions?
Yes. Sizing supports VTOL hybrid platforms, and when paired with a compatible ESC, propeller stop-position control can be used during vertical transition to reduce ground-contact risk — a capability specific to electric propulsion that isn't available on gasoline-driven cruise systems.
How much does propeller weight actually affect flight time on an electric platform?
On battery-powered fixed-wing and VTOL platforms, every gram of propeller weight is offset against battery capacity or payload. A propeller roughly 45% lighter than comparable market alternatives translates directly into additional usable battery mass or extended endurance for the same total aircraft weight.
Can RAYI match a propeller to our specific electric cruise motor?
Yes. Send us your motor's KV rating, target voltage, and mission profile (endurance vs. cruise speed priority), and our team will recommend or custom-design a diameter and pitch combination matched to your motor's operating curve.
Do you support OEM branding and low-MOQ prototype orders?
Yes — custom pitch, custom hub, private-label packaging, and small prototype batches are available for teams validating a new electric or hybrid-VTOL airframe before committing to full production volume.
What is the lead time for bulk electric fixed wing propeller orders?
Lead times depend on quantity and whether the specification is stock or custom. Contact our team with your target volume and delivery window for a firm quote.
Not sure which model fits your aircraft?Send us your aircraft, motor, battery and installation parameters. Our team will help evaluate a suitable standard or customized electric fixed-wing propeller.
