I have some terrible flocks of dust inside my FE
 

I received my Letus FE today, but there is a big dust flock on the inside of the Letus' lens, where the tape is. I just tried to pull off the tube on the side that goes on my camera, but i couldn't get it to move and I don't feel confident enough to pull any harder. The adapter is unusable as it is now. I can't deliver a video to the client with a big black flock of dust on the screen.

Does anybody what to do now?

If there are no screwholes in the rear tube where it fits onto the back of the flip enclosure, then to get some leverage to crack the glue bond without damaging the end of the tube, you might need to drill a small hole in the tube.

I think you should start first at the front end of the flip enclosure. The reversed single element lens there can show dust and may be where the dust you see is.

If you do get the front and back tubes off and the single element lens out of the front of the flip enclosure, blow some canned camera air through the enclosure while holding the opposite opening close near the screen of a operating CRT television set.

The dust tends to jump through to the screen due to electrostatic attraction.

Do not open the flip enclosure itself or loosen the two big screws.

There is no need to do this because dust can be blown out with canned camera air. If you open the flip enclosure like the clip shows, some of the mirrors will be loosened and may become damaged.
