Ok, I have had the Belt cp for just over 2 weeks now and am loving it. I have had to rebuild the head once (b/c of my first crash) and have had to adjust the main blades many times. The tail blades should be loose as they spin they will straighten (just like the main blades). I never did figure out what the stick velcro was for. If you crash and rebuild the head like I did be sure the double check the tracking of the blades and the pitch of the main blades and flybar if these are off by just a little the bird will not fly as stable as it dose right out of the box.
