Best & Fast Prototype ($2 for 10 PCBs):
Thanks to JLCPCB for supporting this video.
First of all. I don`t know how this plane will fly. Couldn`t test it. You have the STL files below. If you want to print your own, download them and test it out, feel free to do that. If you want, share a test video with me and I`ll post it on my blog.
If you fly a drone or RC plane then you will really want to build or buy one of these devices because it can make a huge difference to the safety of your flying
