Install the completed head assembly on the main shaft. Make sure the two pins in the bottom of the head block go into the holes in the mixing base. Also confirm the mixing base will slide freely up/down these pins. Look through the bolt hole in the head block and rotate the main shaft by spinning the main gear until you see the bolt hole in the main shaft line up. Insert the bolt (1) and nut (2). Note: The nut will go on the side with the hexagonal hole. Do not overtighten this bolt. Get it a little past snug. If you tighten too much then you will have a lot of pre-tension that will increase the chance of the bolt snapping in two. Connect the short side of the oval link to the flybar control arm (19 on page 16) and the long side to mixing control arm (7 on page 8). Next make two links with rod (4) and links (5). Set the length to 100mm. Connect one side to the long end of the mixing lever (22 on page 16) and the other to the swashplate.
Install the canopy stand-offs (6). Thread the all-thread bolt (3) into the stand-off (6) and then screw into the bolt hole in the back/top of the frameset (by the gyro platform).
