Yesterday Was the first successful transition flight of my Nano Quadplane. After limited success a few years ago with two separate pixhawks on the VTOL Anaconda, I decided it wasn't feasible to use multiple Pixhawks/Pilots for anything other than a tech demo.
Now with all of the work done by the Devs for creating the quadplane code (awesome work gents!), I was inspired once again to make something that worked as seamlessly as imagined back then. I knew there would be challenges and a large margin for failure, so I chose a small EPP plane to minimize damage and rebuilding. Turns out I don't think I've ever seen a quadplane that uses Arduplane/pixhawk this small, so I thought I would share this with everyone. It took about a week to make and probably took it apart and back together no less than 10 times...seriously there is so much crammed in the fuselage I don't think there is room for air.
In this flight I was running Arduplane 3.7, and have yet to test some of the advanced features like weathervaning and pusher motor position hold assist. Using old batteries so I can only hover for about one minute, so no time for autotune. All gains were done manually the old fashioned way, though they still aren't perfect. Now that I am confident and familiar with the code, I will try again on a much larger model (2 meter+ wingspan) with decent flight time and payload carrying ability.
