Hi ,

does anyone use the Polar Pro Nd filters ( not the cinema ) ?  I can't get the ND8 off , its completley stuck and i'm scared to death i'm going to damage the gimbal , but I now cant fly as the gimbal wont calibrate with the filter attached !! Can anyone please help ?

Put the Mavic body in the freezer for an hour and see if that helps. Though be careful if the air in your home is particularly humid. You could get some condensation inside the body when you remove it from the freezer.

Seriously ... the freezer . !!!

Don't do this. {:4_157:}

i find twisting helps

Don't do this.

Why not? What am I missing? No battery would be installed...heck, some people FLY them in sub-freezing temps well below the 32 F operational limitation stated in the manual. Other than potential surface condensation, what's the issue? A couple thousandths of an inch in contraction could loosen the fit enough to easily remove the filter.

The camera may contract in the freezer but so will the ND filter..The filters are lined with a foam on the inside. I don't get how can it be  stuck so bad that it won't come off.

Polar video was saying you have hotdog fingers

When installing and removing the PolarPro filters on mine, I do it with the plastic gimbal brace snapped in place. With the tips of my fingers grasping both the plastic brace and the camera with one hand, and manipulating the filter with the other, I've had zero problems so far. I've found the fit to be perfectly snug.

I bought the cinematic 6-pack (vivid and shutter) - love these new filters. They all ride through gimbal initialization without a hitch.

What do you think would contract first, the camera or the filter?

There is a reason why in other applications when heat is used to remove seized components it is to expand the stuck item rather than to try to contract the item it is seized to.

Camera or filter first? Don't know for sure, but yes, I'd suspect the filter. But I also know that different metals expand and contract at different rates. Point is it's worth a TRY, no? If it works, great! If not, Plan B...
