I thought as a website called DIY Drones, this might be a good place to post a blog about exactly that. This is my DIY drone (or UAV as I prefer to call them). I had already built a 650mm hexcopter with brushless go pro gimbal and so after doing that I decided to build something a bit bigger so my next project is going to be a heavy lift Octocopter and 3 axis gimbal for a DSLR size camera.
I have completed the gimbal today and below is a video of the results. I have to say its the most technically challenging build I have ever done and I've also learnt that carbon fiber is not the nicest material to cut and sand! but have a look and see what you think.
