Tailsitter vtol with coaxial motors

PX4 Autopilot VTOL 🚁
1

Hi, I want to use coaxial motors with the props spinning in the same direction, with my tailsitter_vtol config. The said tailsitter doesnt have any flight control surfaces.
can I just switch using
R: 4x 10000 10000 10000 0 with “R: 8c 10000 10000 10000 0”
thanks

I set the mixer name as “etc/mixers/vtol_quad_x.main.mix” in the flash
R: 8c 10000 10000 10000 0
Added an “/etc/config.txt” in flash with
set PWM_OUT 12345678

Hi, I still had no success in converting my quad-tailsitter vtol to coaxial_oct,
added
etc/mixers/vtol_quad_x.main.mix ->R: 8c 10000 10000 10000 0
added
etc/config.txt -> set PWM_OUT 12345678
now the other 4 motors spin regardless of being armed or not.
Is it possible for me to have the first 4 motors and the last 4 motors have identical output? clone the mapping for the 2 set of motors. Maybe like two set of? how does one do the mapping?
R: 4x 10000 10000 10000 0
R: 4x 10000 10000 10000 0

Got it working…
only settings to be changed are:
etc/mixers/vtol_quad_x.main.mix ->
R: 8c 10000 10000 10000 0

etc/config.txt ->
set PWM_OUT 12345678
set param set VT_MOT_COUNT 8
