How many centimeters is the five-inch paddle of the traversing machine: hot topics and data analysis
Recently, there has been a heated discussion among fly-through enthusiasts and professional pilots about the size of five-inch propellers. As an important part of the flying machine, the size of the blades directly affects the flight performance and control experience. This article will combine the hot topics on the Internet in the past 10 days, analyze the actual size of the five-inch paddle in detail, and provide structured data for readers' reference.
1. What is the actual size of a five-inch paddle in centimeters?

The "five inches" in a five-inch paddle refers to the diameter of the blade, and 1 inch is equal to 2.54 centimeters. Therefore, the theoretical diameter of a five-inch paddle should be 12.7 cm. However, there may be slight differences in actual production. The following is the actual measured data of mainstream five-inch propellers on the market:
| brand | Model | Actual measured diameter (cm) |
|---|---|---|
| Gemfan | 51466 | 12.8 |
| HQProp | 5x4.3x3 | 12.7 |
| DALProp | T5045C | 12.6 |
2. The impact of five-inch propeller size on flight performance
Blade size is one of the key factors affecting the flight performance of a traversing aircraft. The following is a comparison of the performance of five-inch propellers and other sizes of propellers:
| Blade size | Thrust | Response speed | Applicable scenarios |
|---|---|---|---|
| Five inches (12.7 cm) | medium | Fast | Racing, flying flowers |
| Six inches (15.24 cm) | high | medium | long haul flight |
| Four inches (10.16 cm) | low | Extremely fast | indoor flight |
3. How to choose a five-inch paddle that suits you?
When choosing a five-inch paddle, in addition to size, you also need to consider the following factors:
1.Material: Common materials include PC (polycarbonate) and nylon fiber, the former is more durable and the latter is lighter.
2.Number of blades: Three-blade propellers and four-blade propellers are the mainstream choices. Three-blade propellers are more efficient and four-blade propellers are more stable.
3.pitch: The larger the pitch, the greater the thrust, but the power consumption will also increase.
The following are recommended scenarios for different five-inch paddles:
| Model | Material | Number of blades | Recommended scenarios |
|---|---|---|---|
| Gemfan 51466 | PC | clover | racing |
| HQProp 5x4.3x3 | Nylon fiber | clover | Hua Fei |
| DALProp T5045C | PC | Yotsuba | shooting |
Maintenance and maintenance of four- and five-inch paddles
In order to extend the service life of the five-inch propeller, routine maintenance is essential:
1.Regular inspection: Check the blades for cracks or deformation before flying.
2.clean: Use a soft cloth to wipe the blades to avoid dust accumulation.
3.store: Store the paddle in a dry, dark environment away from heat and moisture.
5. Summary
The diameter of the five-inch paddle is approximately 12.7 cm, making it ideal for cross-country racing and flower flying. Through the structured data in this article, I believe readers can have a clearer understanding of the size, performance and applicable scenarios of the five-inch paddle. Whether you are a newbie or an experienced player, choosing the right blade can significantly improve your flying experience.
