Multi-rotor UAV Propeller Manual Variable Pitch Series
Simplicity over complexity, Consistency in Performance


Specially designed to address the issues of low flight efficiency at high speeds and high altitudes, this series is suitable for aircraft development and professional users requiring rapid switching across multiple scenarios.

Flexible and easy-to-use drone propulsion system enhances flight efficiency in various operating conditions. Typical application scenarios include high-speed flight, high-altitude flight, adjustments for overall aircraft weight, and fine-tuning of custom propeller performance. Limitations of Traditional Propellers: Fixed pitch and fixed aerodynamic characteristics leading to limited power and flight condition matching. Drawbacks of the adjustable propellers available from the market: Low adjustment precision, complicated operation, requires large auxiliary tools, and cannot be quickly adjusted on-site. T-MOTOR (New) manual adjustable variable-pitch series solution: Designed for complex and changing working conditions with diverse power demands, we provide flexible solutions that allow for quick manual pitch adjustment by simply changing the positioning blocks.

Quick Assembly and Disassembly Precise and Reliable
Quick to replace without requiring professional training—easy to learn and use. The pitch adjustment accuracy remains unaffected by manual operation errors with user-friendly operation.

Methodical Approach
Using calculation tables derived from extensive experimental data, users can quickly find the required pitch angle based on the operating scenario and simple parameters. (7.5°, 10°, and other positioning blocks are available upon request for customization)

Flight Speed	0~10m/s	5~15m/s	10~20m/s	15~25m/s	20~20m/s
Positioning Block	0°	2.5°	5°	7.5°	10°
Flight Altitude	0~1000m	0~2000m	0~3000m	1000~4000m	2000~5000m
Positioning Block	0°	2.5°	5°	7.5°	10°

Performance Comparison
The efficiency curve of three positioning blocks (pitches) under different airflow speeds (Example: MN605 KV170 + FLAME 180A 12S V2.0 + MF2211VP, Flight inclination 30°,S0, S5, S10, S15 respectively represents speed 0m/s, 5m/s, 10m/s, 15m/s. D0, D2.5, D5 respectively represents 0° positioning block, 2.5° positioning block, and 5° positioning block.)


Conclusion: As the positioning block angle (pitch) increases, the efficiency of the propeller improves at higher airflow speeds.

Multi-adaptability
The manual variable pitch propellers can not only support multi-rotor aircraft, but also effectively adapt to the needs of vertical take-off and landing aircraft, providing higher flexibility and performance to meet the requirements of different flight missions.
