i have solve the problem, reseting all parameters and re installing fw 3.2.1 was the solution
tried yesterday
tune via ch 6 alt_p, ins_mpu filter set to 20,
adjust thro_accel and rate
i have played around with this even the refresh rate of esc, i have chek logs for vibration and seems okay according to what ive read,
chek also for baro error but it seems ok
it also pulsate even if props are remove, you can hear them.sounding like pumping
Have you tried the auto tune feature?

Also they are going to pulsate as they are trying to maintain altitude right. If the wind blows then pressure is changing. Do you have a case over your sensor on the chip? Is there foam over it to reduce airflow?
