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??
