Next install the flybar control arms. This assembly comes together in the kit but it is not tightened. Align it so that the set screws are on the top. Get the flybar from the bag that has the tailboom in it Slide it through the flybar control arms taking note that there are two flat spots on the flybar. These flat spots need to be up and directly under the set screws that go in the flybar control arms. Hand tighten just one of the set screws. Now we take a moment to make the two links that will go on the flybar control rods. The links will be set to 39.5mm from the centers of the holes. Align the links so the letter 'A' on the links are on the same side.

Now you need to hold the head upward and install one of the links on the left side with the letter 'A' facing you. The link on the right needs to have the letter 'A' away from you.

Now to continue with the flybar control arm assembly. Slide the loose flybar control arm against the flybar control rods and hand tighten the set screw onto the flat spot of the flybar. Apply blue loctite to a couple of the M3x5mm bolts and tighten them into the flybar control rods. Now remove the other two M3x5mm bolts from the other side, apply blue loctite and retighten them on the flybar control rods.

Next you need to check the flybar position. Use a straight edge ruler to measure the distance from the flybar control arm to the end of the flybar. Like in the picture below but you are measuring to the end of the rod (you will install the paddle after this). If both sides are not the same then loosen the two set screws and shift the flybar toward the shorter side then check again. Once you have it centered remove just one of the flybar control arm set screws, put blue loctite on it then tighten it in place. Now do the same for the other side.

Install the flybar paddles next. The thicker side of the paddle is called the 'leading edge'. The thin side is called the trailing edge. Install the paddles as shown in the photo, the leading edge is the side that goes forward into the air from a clockwise rotation as viewed from above the rotor head. Make sure that the paddle is screwed on far enough that the hole for the set screw goes past the threads. Use a straight edge ruler to set both paddles the same distance from the flybar control arms.

Align the paddles with the flybar control arms. As you can see from the picture below the centerline of the paddle is parallel to the flybar control arm. Do this for both paddles then verify you have them paddle aligned correctly by looking at the assembly as shown in the second picture. Notice the red arrows, the trailing edge tips are both in the center of the flybar while at the same time the flybar control arms are also both visually centered on the flybar.
