When you start building a drone, the first thing you probably need to decide is the frame of your drone; size, materials, thickness, area, style, and even geometry will play a critical role in your build.
Frames hold FPV Cameras, Flight Controllers, Video Transmitters, and other related electronic components securely. They have specific mounting points to mount each component and hold them in place firmly. Therefore, every pilot should equally prioritize purchasing an FPV frame that suits their flight needs.

Drone Frame Size
Drones come in various sizes, from "nano" sizes smaller than your palm to mega sizes. The most common frame size, which most people refer to as a 5-inch frame, is around 210mm. It's commonly used for both freestyle and racing as it offers the best compromise between agility, weight, and responsiveness.
While frame shape can influence the size of accessories, primarily, you can work around the following according to the table:

When choosing the frame size, you need to consider several factors:
- Portability: Larger frames can be bulkier and more challenging to transport.
- Agility: Smaller frames are typically more agile and responsive.
- Flight Time: Larger frames can accommodate bigger batteries, potentially allowing for longer flight times.
- Payload: Larger frames can carry heavier payloads, such as high-quality cameras for aerial photography.
Frame Materials
The choice of frame material affects the drone's weight, durability, and performance.
- Carbon Fiber: Carbon fiber frames are lightweight and strong, making them ideal for racing drones and freestyle drones where agility and durability are essential.
- Aluminum: Aluminum frames are sturdy and can withstand crashes, but they tend to be heavier than carbon fiber frames.
- Plastic: Plastic frames are lightweight and inexpensive, but they may not be as durable as carbon fiber or aluminum frames.
Overall, carbon fiber is the most popular choice for drone frames due to its combination of strength and low weight.
Frame Design
The design of the frame can also impact the drone's performance and handling.
- X-Frame: X-frame designs are popular for racing drones because they provide better weight distribution and agility.
- H-Frame: H-frame designs offer more space for mounting components and are often used for freestyle drones and aerial photography drones.
- True-X: True-X frames have symmetrical arms, making them well-balanced and agile.
Ultimately, the best frame design depends on your specific needs and flying style.
Additional Considerations
When choosing a drone frame, here are some additional factors to consider:
- Price: Consider your budget when choosing a frame. Carbon fiber frames tend to be more expensive than plastic or aluminum frames.
- Compatibility: Make sure the frame is compatible with your preferred flight controller, motors, and other components.
- Weight: The weight of the frame affects the drone's overall weight, which can impact flight performance and battery life.
- Crash Resistance: Look for a frame that can withstand crashes without sustaining significant damage.
By considering these factors, you can choose the right drone frame for your needs, whether you're building a racing drone, freestyle drone, or aerial photography drone.
