So I decided to take a chance on the Cendence/Crystal Sky combo for my Inspire2 Camera Op.

One issue: I seem to be missing the screws that hold the Cendence mounting bracket to the bottom of the Crystal Sky.

Anyone know what type of screw this needs?

Not good, my friend. These are metric (M5) and very custom. Demand re-supply. For now, however, you can get going with socket cap screws (for Allen wrench), if you find some with threaded shank no longer than 10mm. Start looking at local Fastenal supplier ...

Check your packaging. Mine were in a clear plastic bag with smoother items in the bag.

I believe that DJI shipped a batch of Crystal Sky units with either no screws or the wrong screws Mine came with screws that were far too small, when I called my supplier (Heliguy in the UK) they knew about the issue and had ordered a batch of the correct screws, they even cc'd me in to an email to DJI in the Netherlands to request more screws.
