Large drones are widely used in agriculture, aerial surveying, inspection, logistics, and special missions, with propellers being the critical component determining thrust, efficiency, and stability. As platform payloads increase, 24–40 inch carbon fiber propellers have become mainstream. However, different missions have distinct requirements for propeller diameter, pitch, and structural design, making the selection process complex due to the vast number of models available.
To help users quickly find the right platform configuration, this article uses four mission categories—Agriculture / Aerial Surveying & Inspection / Logistics & Heavy-Lift / Special Platforms—as a framework. We have selected large propeller models that are currently common in the industry, have long-term market availability, and possess high engineering verification. This guide summarizes the key parameters and applicable scenarios for each model to form a directly referenceable recommendation list.
Understanding Large Drone Propellers
Large Drone Propellers typically refer to blades with a diameter between 24–40 inches, designed for professional mission platforms such as agriculture, industrial inspection, aerial surveying, logistics transport, and special operations. Compared to small or medium propellers (5–22 inches), large propellers exhibit significant differences in thrust capacity, structural strength, energy efficiency, and wind resistance stability, making them the core component of commercial UAV power systems.
The industry generally classifies propellers by size as follows:
Small Props (≤12 inch): FPV, light-load high-speed drones.
Medium Props (13–22 inch): Aerial photography, multi-sensor inspection, and light-load surveying.
Large Props (24–40+ inch): Agriculture, industrial mapping, logistics, and special platforms.
The "Large Drone Propellers" discussed in this article refer specifically to those above 24 inches, primarily used for high-payload, long-endurance, and high-stability tasks.
1. Core Characteristics of Large Drone Propellers
(1) High Static Thrust Output
Large propellers can generate powerful static thrust at low RPM, making them suitable for high-payload takeoffs, hovering for spraying, and lifting operations.
(2) High Efficiency at Low RPM
A larger propeller disk (disk area) means lower disk loading. This gives large propellers a distinct endurance advantage during mid-to-low throttle cruising, which is crucial for long-endurance missions.
(3) Wind Resistance & Vibration Control
Large propellers offer better stability in turbulent environments and reduce vibration amplitude, ensuring data quality for precision equipment like LiDAR and multispectral cameras.
(4) Motor Compatibility
Large propellers must be paired with low KV, high-torque industrial motors to form the standard propulsion system for high-payload UAVs.
2. Applicable Mission Scenarios
Large propellers are standard configurations for professional mission drones, primarily appearing in the following four scenarios:
Agricultural Spraying (28–32 inch): Long-duration hovering, high payload, corrosive environments.
Industrial Inspection & Mapping (24–28 inch): Low-throttle cruising, stable vibration control.
Logistics & Heavy-Lift (30–36 inch): High thrust output, strong wind resistance.
Special & Ultra-Large Platforms (36–40+ inch): Extreme payloads, tethered lighting, engineering lifting, hybrid gas-electric platforms.
Different scenarios require different dimensions, structures, and performance specs. To help you quickly find mainstream specifications, we will introduce representative models for each category below.

How to Choose Large Drone Propellers?
1. Large Drone Propeller Matching Table by Mission Type
Mission Type | Typical MTOW | Recommended Propeller Diameter (inch) | Motor KV Range | Core Requirements |
Industrial Inspection / Mapping | 5–15 kg | 26–30" | 150–180 KV | High efficiency, low vibration, long endurance |
Agriculture Spraying / Spreading | 10–30 kg | 28–32" | 120–150 KV | Strong static thrust, wind resistance, structural strength |
Logistics Transport / Heavy-Lift Platforms | 20–40 kg | 30–36" | 80–120 KV | High thrust, long endurance, high torque output |
Special-Purpose / Extra-Large UAV Platforms | 40–100+ kg | 36–40"+ | 50–80 KV | Large disk area, extreme load capability, safety redundancy |
2. How to Choose Large Drone Propeller Material?
Large drone propellers work under high loads, long hovers, and high torque; thus, material strength and rigidity directly affect flight safety. Propellers above 24 inches universally use Full Carbon Fiber structures. This is currently the only mature material capable of maintaining a stable shape, reducing deformation, and extending fatigue life under high torque conditions.
Compared to plastic or standard composites, full carbon fiber offers superior dynamic balance consistency, durability, and reliability in high-strength scenarios, making it the industry standard for large agricultural, mapping, logistics, and special platforms.
3. How to Choose Large Drone Propeller Structure?
Common structures include Fixed Propellers and Folding Propellers:
Fixed Propellers: Simpler structure, higher rigidity. They perform more stably in heavy-lift flights, high-torque environments, and continuous output scenarios. They are the mainstream choice for engineering lifting, logistics, and 36"+ large props.
Folding Propellers: Better suited for agriculture and mapping tasks requiring frequent site transitions. They are easier to store and reduce the risk of damage during transport. Modern folding mechanisms are sufficiently reliable in hub strength and dynamic balance to meet the needs of medium-to-large drones.
4. How to Choose Large Drone Propeller Pitch?
Pitch determines thrust, current (amperage), and vibration characteristics. The industry generally uses a medium pitch of 8–12.5 inches. This strikes a good balance between thrust output and motor load, ensuring efficiency and stability during mid-low throttle cruising and long hovering missions.
Pitch too high: Stronger thrust, but leads to increased current draw, higher vibration, and difficulty in flight control tuning.
Pitch too low: Insufficient thrust and reduced efficiency.
Therefore, large drones typically select a medium pitch to achieve safe, stable, and easy-to-tune overall flight performance.
Summary
Different mission types place very different demands on propellers:agriculture focuses on strong static thrust,mapping emphasizes low vibration and cruising efficiency,logistics platforms require a high thrust-to-weight ratio,and special-purpose UAVs prioritize structural rigidity and redundancy.This article summarizes a range of proven,commercially available large-diameter propellers across four core application scenarios,providing clear specification references for platforms of various payload levels.
