I just want to draw attention to some good work being done by Rcgroup's NightHawk to make Ardupilot run on Revo class boards. The thread is here: https://www.rcgroups.com/forums/showthread.php?2784349-Ardupilot-on-OpenPilot-Revolution
This means yet another target for the ever versatile Ardupilot. What makes it interesting is that I have felt that Ardupilot is falling behind the curve a little in All-In-One boards. Potentially this opens up board like https://www.fpv303.com/product/airbot-omnibus-f4-pro-v3/ with integrated OSD, Volt/Current monitoring, logging etc.
Anyhow -- this posting was just a pointer to anyone that wants to support and encourage this development. It also means we can potentially run Ardupilot and iNav on the same hardware. I believe Pixracer also can do both as well. For those who enjoy open source autonomous flying, especially fixed wing, this is a welcome development.
