Quad tailsitter autopilot orientation

When configuring the quad X tailsitter, what is the default autopilot mounting orientation? Is it the same the Caipiroshka build log (with X axis pointing to the nose of the wing), or is it similar to the orientation for a quad-X multicopter (eg F450 with X axis pointing to the front of the x?)

Is quad X tailsitter airframe like the google UAV to take off?

Are your problem solved? I met the same problem!
