Tailsitter biplane+4 motor

Hello,
I´m trying to find the configuration for a tailsitter with 4 motor and bi-plane configuration. Something like this: https://journals.sagepub.com/doi/pdf/10.1260/1756-8293.7.4.395

But I only can found information about the tailsitter with 2 motors, anybody could tell me where can I find info for this configuration?
Thanks in advances!!!

Take a look at this post:


The tailsitter quad X configuration will support the frame geometry pictured here:

Note that the PR with the new frame type with torque-based yaw has not yet been merged to master though. The quad X copter tailsitter in master should work too though.

I guess the wiki needs updating to include a description of support for “copter tailsitters”.
The parameter which selects this frame type is:

For a quad Tailsitter you would set Q_FRAME_CLASS to 1, Q_FRAME_TYPE to 1 and Q_TAILSIT_MOTMX to 15 if you want all 4 motors running when in forward flight. If you wanted to shut down 2 of the motors in FW modes, you would set MOTMX to 3 or 12, depending on which pair you wanted active.
