OK, another question along these lines - I stupidly experimented with idle up, and ended up twisting my tail boom, broke a ball off one rotor grip, and lost a linkage from the rotor grip to the seesaw. Bought new parts (rotor grip, linkage set), and got everything back together, and it flies fine, but the side of the rotor grip that is for the nut to go into is on the TOP (I swear it was on the bottom originally, and the exploded views shows the screw entering from the top!) Remember, only one linkage was lost - I have looked and looked and can see no way things could have gotten so twisted around to reverse this setting! The ball on the grip is on the training edge of the blade, as it should be!!! Just now the nut is on top, rather than on the bottom! My setup looks EXACTLY like the rotor head exploded view!
What's up??
I believe that they come a left and a right grip, that'll put the nuts down where they belong. But it seems to me, that I've done like you before, just inserted the screw, held the nut and tightened everything down and it worked fine.
if you are using your exploded views in the manual - it will show one blade grip the wrong direction, either look at the update on their website or remember that when the head is spinning, the balls should be on the following (trailing) side.

this will show you the right orientation for everything.
