Specs and Features

The GoPro Session 5 was a popular choice for FPV pilots, but its discontinuation left many in search of a replacement that could offer similar features and convenience. The Caddx Walnut HD camera has risen to the challenge, providing FPV pilots with an affordable and reliable option that can deliver stunning footage without breaking the bank.

In addition to its impressive 4K resolution and 60 frames per second, the Caddx Walnut HD camera also features Gyroflow Stabilization support, which helps to stabilize the footage and ensure that your videos are smooth and clear.

The compact cube shaped camera, weighing only 60 grams, is almost the same size as the GoPro Session and shoots at 60 FPS in 4K and 120 FPS in sensor with a wide field of view of 150 degrees.

Although the camera’s protruding lens may make it challenging to fit into normal session mounts, this can be easily solved by sliding it in as usual. The camera has a USBC slot and an SD card slot that supports up to 256GB, providing ample storage for your footage.

Closer Look at the Walnut

The Caddx Walnut HD camera is a lightweight and portable option for FPV drone pilots, measuring just 38x36mm and weighing approximately 64 grams. I appreciate the fact that it comes with ND8 and ND16 filters, making it ideal for recording on bright, sunny days.

One of the standout features of the Caddx Walnut HD is its impressive image quality for what you are paying for. With a 1/2.3 inch HDR sensor, the camera captures crisp and natural colors, and it handles exposure well even in low light conditions. The camera’s field of view is 150 degrees, and it supports video encoding in either H.264 or H.265 formats. The camera also supports Wi-Fi and has a maximum video bitrate of 100Mbit/s.

Setting up the Caddx Walnut HD is straightforward, while the controls may take some getting used to, they are easy to learn with practice. The Caddx Walnut HD camera is easy to use and can be controlled with a mode button, allowing for quick switching between different modes.

The camera’s image quality is excellent for the price, with recent firmware updates further improving the quality. The camera’s white balance is good, and the footage is clear and vibrant, with only minor issues with over-exposure in certain lighting conditions. The camera handles changes in lighting pretty well too.

However, one potential downside of the Caddx Walnut HD is its battery life. With a 1S 600mAh battery inside, it gives you around 30mins of runtime which is adequate for most drone flights. And if you want to fly longer, you can charge it easily with the magnetic charger and adapter provided, which also keeps it waterproof. Additionally, the camera can get hot during recording, so it’s important to ensure good airflow over the camera.

The camera comes with an app that allows users to adjust settings and view footage in real-time. The app is easy to use and offers a range of options, including resolution, audio, video encoding, and LCD. The app also allows users to stabilize footage with gyro flow, which is a free application that can smooth out footage and create a more professional look.


Overall, the Caddx Walnut HD camera is a great option for FPV pilots who are looking for a budget-friendly alternative to more expensive action cameras like the GoPro mini 11, DJI Action, and Insta360 Go. Its small size, weight, and features make it an ideal choice for beginner FPV pilots. While the camera has some minor limitations, such as battery life and occasionally over-exposed image in certain lighting conditions, these are outweighed by the camera’s affordability, ease of use, image quality, and range of features. But if you are looking for top of the line image quality, then the GoPro is still my go-to camera.

Oscar. Thank you for ALL of your info on fpv. I was wondering if it’s possible to use the gopro balance bec power cable on this. I know it comes with one but there’s too much to do toget it powered. Any suggestions on this would be great.
