Help me Tune this quad

Hi,

I’ve been trying to tune this quad since a couple of weeks but cant get any progress done

Its a 600mm Quad with 14inch propeller and a 6s li-ion battery

I’ve followed Tuning instructions very carefully still cant get a stable tune
Today I tried autotune but couldnt even complete one axis in 25mins while my other 10inch quad completes all three axis in 10mins

What am i missing?

A log of Auto Tune is not that useful. Reset the parameters as per the Initial Tuning Setup page in Mission Planner for 14" on 6S li-ion as many of them are not now. Then make a typical flight, not Auto Tune, and post that log.
