Couple tips for APC props...

1: They're sharp! Break the edges with sandpaper to save your fingers! Goes for all props, but APC is sharpest of all!
2: They're Ugly (I think), but you can dye them any colour you like with RIT clothing dye. Boil up and dip!
3: They get hard with age, but boiling them will restore their flexibility

Master airscrew is what I use on trainers, they'll survive many a groundstrike and even a few noseovers!
