I cut some regular printer paper in half (to 5.5x8.5") put it in the printer tray, and used Adobe Acrobat to print it front and back. Used a 3-hole punch and put it in a medium size 3-ring notebook.... along with the manuals for my Phantom 3 Std, P3Pro, Litchi, etc. It irks me that the GO4 and FLY manuals are on-line only, and stretched across 10+ webpages - makes it hard to copy/paste so haven't done that yet.I downloaded it too; but not being the nice hardcopy, after a couple months of not flying, I forgot it existed
