170g Propeller for 1050mm Wheelbase Heavy-Lift UAV Missions

Description

Company Background: Ningbo Gemfan Hobby Co., Ltd. and the GEMFAN Brand

Gemfan Hobby Co., Ltd., operating under the brand abbreviation GEMFAN, has been established for 15 years and maintains business coverage across more than 60 countries and regions, including China, the USA, the UAE, Europe, and Australia. This global footprint provides context for evaluating the company’s Large Wheelbase 3-Blade UAV Propeller Series, a product line built specifically to address the propulsion demands of medium-to-large industrial-grade UAVs.

Industry Pain Points Driving Product Development

Industrial-grade UAVs performing inspection, mapping, and agricultural plant protection tasks routinely face a set of interconnected challenges: increased payloads from equipment such as LiDAR and spraying systems, insufficient flight stability, low power system efficiency during high-intensity operations, and motor overheating. In response, GEMFAN’s strategic positioning centers on the R&D of UAV propulsion system components, with a focus on optimizing aerodynamic structures and upgrading material technologies to deliver high-thrust, high-efficiency, and smooth-running propeller solutions. The company’s team brings years of experience in propulsion system R&D, with particular expertise in precision dynamic balance control and material application technologies.

Product Deep Dive: A Propeller Built for 1050 mm Long-Wheelbase Heavy-Lift Missions

Within the Large Wheelbase 3-Blade UAV Propeller Series, one unit is positioned as the basic component for heavy-lift UAV missions with a 1050 mm long wheelbase. This propeller carries a single weight of 170g, a propeller diameter of 508mm, and a 10-inch pitch.

Target Scenario Pain Points

For industrial inspection, emergency mapping, and long-endurance security surveillance, existing small-size or two-blade propellers often struggle to deliver sufficient thrust, high stability, and flight safety when the aircraft must carry heavy equipment through complex wind fields. This propeller is engineered specifically to close that gap.

Key Differentiated Value

• Heavy-load Capability: The 20-inch large diameter combined with a 10-inch pitch provides greater static thrust at low RPM, effectively improving endurance and operational efficiency under heavy mission payloads.
• Wind Resistance & Image Stabilization: The three-blade configuration increases propeller disk solidity, enhancing airflow stability and gust resistance. This ensures a stable platform attitude in strong winds or turbulent conditions, safeguarding data acquisition quality.
• Dynamic Balance Consistency: High-precision molds and dynamic balancing processes reduce high-frequency vibrations, extending motor and flight controller lifespan, and improving long-term reliability in field operations.

Key Specifications

• Propeller Diameter: 508mm
• Pitch: 10 inches
• Single Weight: 170g
• Center Hole: 8mm + six-hole adapter ring

Adaptation Scheme

This propeller is suggested to pair with 6215-class motors, suitable for quadcopters with a takeoff weight of 12–14 kg, and compatible with 1100mm wheelbase platforms.

General Technical Features Shared Across the Series

The 170g propeller shares core engineering principles with the broader Large Wheelbase 3-Blade UAV Propeller Series, which includes the following general technical features:

• Three-Blade Aerodynamic Structure Design: Compared to traditional two-blade propellers, it has a larger air interaction area per unit diameter, providing more stable thrust and effectively reducing flight vibration.
• Enhanced Thrust Efficiency: Following the principle of large-diameter propellers pushing greater air mass at low RPM, it reduces energy consumption and is suitable for long-time hovering and cruising.
• Low Noise Advantage: Lower operating RPM helps reduce noise pollution during flight, better aligning with industrial application environment requirements.
• Mainstream Platform Compatibility: Specifications cover 16–18 inches, precisely matching current mainstream 800–1200mm wheelbase industrial UAV platforms.

These shared characteristics explain why the 170g, 1050mm-wheelbase unit performs consistently with the rest of the series: the same high-precision mold manufacturing and dynamic balancing processes that reduce vibration and extend component lifespan across smaller units are applied here at the larger 508mm scale, where the stakes for stability and reliability are higher due to increased payload and wind exposure.

Industry Adaptation and Value

The broader propeller series, including this 1050mm-wheelbase unit, is positioned to serve several industrial use cases:

• Industrial Inspection: Improves flight stability for power line, oil pipeline, and infrastructure inspections.
• Aerial Survey and Mapping: Meets requirements for high-efficiency, long-endurance cruising, ensuring data collection precision.
• Agricultural Plant Protection: Provides stable thrust reserves to support heavy-load attachments such as spraying systems.
• Multi-rotor Model Aircraft: Meets customized needs for high-performance propulsion combinations.

For operators running long-endurance security surveillance or emergency mapping missions on 1050mm-class airframes, the combination of heavy-load capability, wind resistance, and dynamic balance consistency addresses the specific pain points outlined above: insufficient thrust reserves, instability in gusty conditions, and vibration-driven wear on motors and flight controllers.

Summary: Matching the Propeller to the Mission

Buyers evaluating a 170g single weight propeller for a 1050mm long wheelbase heavy-lift UAV should weigh the following factors drawn directly from the product’s specifications: a 508mm diameter and 10-inch pitch tuned for heavy payloads, an 8mm center hole with a six-hole adapter ring for mounting flexibility, and a recommended pairing with 6215-class motors for airframes in the 12–14 kg takeoff weight range on 1100mm wheelbase platforms.

This unit is part of GEMFAN’s Large Wheelbase 3-Blade UAV Propeller Series, produced by Ningbo Gemfan Hobby Co., Ltd., a company with 15 years of operating history and a presence across more than 60 countries and regions. The propeller’s design reflects the company’s stated strategic focus: optimizing aerodynamic structures and applying high-precision dynamic balancing manufacturing to meet the propulsion demands of medium-to-large industrial-grade UAVs performing inspection, mapping, and plant protection work. For teams sourcing propulsion components for heavy-lift missions on 1050mm-class wheelbases, this specification set — 170g weight, 508mm diameter, 10-inch pitch, three-blade configuration, and six-hole adapter compatibility — is the direct answer to the requirements outlined for high-precision mold manufacturing and stable heavy-load performance.
