in AC32 is supported the Mixertable as Mikrokopter , so is yet supported any kind of configuration .
If you are working on new design consider to use a MP32F1 for it.
Yes, it's just not supported out of the box in the Mission planner. You need to use Arduino to upload. It's just as simple frame type change in APM_Config.h
#define FRAME_CONFIG == OCTA_QUAD_FRAME
Thanks Jason for reply, but dunno the order of the motor, there's schematic for this config?
It's planned for another drone, dear Roberto...
