This parts guide will show a break down of the newer Angels. It's based off a Speed, but the 4 and 4 Fly are nearly pneumatically identical. The Fly no longer has the Diverter Plate, since there is no COPS Rod installed. Other than that, the difference lies in electronic components and features.

These are the lubes I use for my angel. Don't have any Love Juice or grease, but that will also work great.
White Lithium, available at most hardware stores, and pretty cheap to boot.
KC Trouble Free

The Angel Tool Kit. I highly recommend buying one of these, it makes tuning your gun so much easier. Included is the Guage, used for setting your lpr pressure. The LPR tool, for pulling the lpr piston to add/remove shims. The Ram Extractor, to pull your ram out. The other tool no longer has a use, since the ram design changed, eliminating the external snap ring adjustment.
