Arkbird 2-Axis Mini Airplane Gimbal with HD Camera with PWM Control
Here we have an all in one stabilised camera gimbal from Arkbird. The gimbal will work for both drones and aircraft, but its particularly suited to aircraft as it's inverted - the advantage being you can mount it your airplane's top deck and not have to worry about extending the undercarriage to fit it. It's a nice small unit and at only 80grams flight time should take much of a hit. It’s a lot lighter than using a GoPro and gimbal combination which is typically around 90g for a GoPro and 150g for a gimbal.
The gimbal has 2-axis stabilisation in pitch and roll; you can also control the pitch angle via a spare channel on your radio control.
The camera records 2K resolutions at 30fps or 1080P at 60fps, you just need to install a micro SD card. You can also remotely trigger the camera via PWM. Finally, there is a video output connection should you want to use it for FPV.
