It’s amazing how many variations of hybrid VTOL systems are already out there, and it is even more amazing to see them fly with fully functional autopilots. The E-flite Convergence is a nice little tiltrotor and lots of fun to fly, BUT what if you lose track of it and just want to hit the return button? At UAVenture we specialize in hybrid VTOLs and are always looking for new vehicles to get flying fully autonomous so we put a Pixfalcon in it and installed PX4.
The versatility of the PX4 autopilot makes it possible to easily integrate it into any form of VTOL out there so it only took a few changes and a new mixer to make the Convergence fly (and a bored engineer over the holidays ;)).
