PreArm: inconsistent Accelerometers

Hi guys

I have a massive problem, I have a dropix with copter 3.4.6 and since I installed a servo gimbal, my octo wont arm because the the inconsistent Accelerometers.

the servo gimbal is connected on my FC, so it will power on only after initial calibration, but I think that might be the cause of my trouble or it’s a problem with my FC

Is there any way to delay to power on my gimbal or power it when I arm / pre-arm my drone?

Last week it happened to me so I did another calibration and it work perfectly even with connecting - disconnecting my drone
