I know, it looks like a lot of things to do... no point in delaying, let's get started. Start by placing the two bearings (8) into the flybar see saw hub (21). Note that if you have a 29BB kit then these will be bushings. Slide both hexagon shaped flybar arm bushings (20) into each flybar control arm (19). Make sure you get the bolt holes aligned. Wait just a moment before you put in the set screws (4). Insert the flybar (18) through the bearings in the hub (8). Slide one of the flybar control arms (19) on the flybar and align the bolt hole with the flat spot on the flybar and lightly tighten the set screw (4). There are two of these flat spots on the flybar. Push the flybar control arm up against the hub and install the second flybar control arm on the other side (orient as shown in the picture). Make sure the set screw contacts the flat spot and that you can't move the flybar in/out of the hub. Now measure the length of the flybar from the control arm to the tip. Do the same for the other side. If it is not equal length then loosen the set screws and slide the flybar to center it. Once you get it centered, take out one set screw at a time so you don't loose your position and put blue loctite on them. Next install the ball (31) and screw (3) onto both flybar control arms (19). While you're at it go ahead and install the other four sets of (31) and (3) onto the mixing levers (22). Now insert the bearings (9), two per lever, into the mixing levers (22). Slide the sleeves (13) onto bolts (1) then install through the bearings in the mixing lever. Put the washer (9) on the bolt. Blue loctite on the threads then bolt the assembly to the end hole on the side of the hub (21). Do the same for the other mixing lever.
The last step on this page is to install the flybar paddles (17). Thread them on the flybar until you see the end of the flybar in the cutout window of the paddle. Make sure the short side of the paddles are in front (as viewed by a clockwise rotation from above). Thread on the other paddle and measure the distance from paddle to hub for both sides. Make sure they are equal distances. Now you need to make sure both paddles (17) are parallel with the flybar control arms (19) then install the set screws (5). You can double check by sighting down the flybar to see if the paddles align to each other. The symptom of misaligned paddles will be that you can get one side of the rotor tracked but not the other.

First adjust the flybar paddle closest to you so that it is parallel with the flybar control arm. Once that is done, all other adjustments will be to the other paddle. In the first picture you can see the angle I look at. This position allows you to see the tips of both flybar paddles. Move yourself (not the helicopter) up or down until your line of sight is such that the tip of the paddle closest to you is in the center of the flybar. Then look over at the tip of the other paddle, it should also be in the center of the flybar. If not adjust it so that it is. Don't forget to tighten the set screws in the paddles to keep them from turning in flight.
