Turned a center dimple in the head of the bolt that secures the main rotor drive pin lock and put a drop of red nail polish in the dimple. Got this idea from Juan's build thread to make it easier to sight center the line when stringing the rotor blades later on. Reinstalled the bolt and just lightly tightened it since the head will be coming back off later.
Used dental floss to secure the three pin wire connector that feeds the cyclic grip buttons.
Final installed the AN3 bolts and locking nuts that secure the cyclic stick into the cyclic clevis and the cyclic grip to the top of the stick.
