I see alot of guys with 3 or 4 of the same props size quads, well im here to tell ya its fun and a great idea to have a few purpose quads, i like to rip my 5 inch in tight little spots, and rip my 6 inch when I have the real estate, my 5 inch copters get a little lost in mountain surfing areas , as my 6 inch doesnt do quite as well in super tight areas, but its two diff style, in the comments below let me know what style you like better.
