I performed today successful test flights of my new twin engine puller (tractor) KFm2 RC flying wing with the GoPro Session 5 camera on board.
I wrote an article-report about it. There is a short, two minutes, video of the flight in the article.
The idea is to create an open source ultra-low cost aerial platform with excellent flying qualities which could be built DIY (Do It Yourself) from readily available materials for mapping, aerial photography, journalism, agriculture, etc.
There is also in the article another video of the detailed build of this air-frame.
