I am building a new quadcopter frame for my Ardupilot. Hopefully the frame will be lighter and a lot more agile. I went with a more traditional frame-design this time as you can see in the images. This quad will use the same motors and ESCs as my previus APM quad. The GoPro gimbal will be mounted underneath the main plate, and it will be easily detachable if I want to fly without a camera. There will also be possible to attach other things such as a hard-mounted camera or an FPV-module.
