Arduplane and tailsitter VTOLs

Good fun going on over in RCGroups, VTOL thread, with the little old KK2.1.5 board, Happy Sunday’s excellent software, and Ran’s equally good documentation. But the board is limited. I Desperately need Pixhawk injection.
Does Arduplane support tailsitter VTOLs ?
Please, if anyone could steer me to either PX4 or any other software for this, I’d be most grateful

To my knowledge Arduplane does not support tail sitters. Yet …?
PX4 does I think, you’d have to head over to the PX4 forum.
