Busha , I was very confused with the same issue,,, I find it weird that they would build it this way ,,
one thing is nice about building it this way is that the nut stays in the holder when you change the blades...

One other comment,, I am a newbe in the heli hobby ,, I was told this Axe Cp can be used indoors
say in the living room or family room , I find it way too squirly to fly in my house without getting real
nervous about hitting somthing.....
