For cockpit filming, I currently use a combination of GoPro cameras:
2x GoPro Hero 7 Black
1x GoPro Hero 10 Black
1x GoPro Hero 5 Black
This setup has served me well for the last few years. However, after hundreds of flight hours and far exceeding their original design life, the cameras are starting to show their age. They are slowly reaching the end of their reliable service. In total, the four GoPros cost me around £1,600. Plans to replace them will take place by the end of 2026.
For high-quality external footage, including pre-flight walks, post-flight shots, and “B-roll” during flight, I use a Sony A7 IV mirrorless camera with a suitable lens. This setup costs in the region of £4,000.
I also use a variety of GoPro suction mounts and ball joints, which add another £300–£400 to the overall investment. All in all, building a reliable multi-camera system for aviation vlogging requires a high upfront cost, but it allows me to capture the full story of each flight, from the ground to the airways and back again.
