2.7 m 10 kg Vtol tuning

hello
im currently testing this vtol

wingspan - 2700 mm
weight - 10 kg
cruise motor - hobbywing x6 plus with 2490 prop
batt- 12s3P liion

it feels like its not well balance while flight
tuning seems to be way off
i have no idea of how large model like this is tunes in fixed wing mode
if it was smaller lighter i could have used autotune but Ardupilot doesnt recoment autotune fot this size
