The next step is the flybar seesaw assembly. There are two things in this constructon step that need to be paid close attention. Firstly, the seesaw arms are easily installed upside down. Study the manual carefully and it is not too difficult to see the correct way to assemble them. I'll include a high-res picture below to help with this. Click on the very bottom right picture in the series below, it's not the best shot I could have taken to show this but I think it is clear enough to allow the part to be mounted correctly. Secondly the seesaw hub can also be installed upside down. Again this is very easily avoided and it's very clear in the manual as to what the correct way up is for this part. When looking at the flybar seesaw take note that the grub screws for securing the flybar are screwing into plastic only, so when the flybar is fitted pay close attention to how tight you screw these down as it easy quite easy to strip the plastic thread. Flybar seesaw assembly parts Rotor hub bushing Flybar arms Flybar seesaw Installed flybar arms Installed flybar arms The seesaw assembly can only be installed by inserting the flybar through the hub. At this point I would not bother screwing down the grub screws that hold the flybar in place. Leave this for after the paddles are installed. When installing the paddles it is important to make sure that the paddle is parallel and in line with the seesaw. Both paddles should be perfectly aligned and parallel, otherwise flight characteristics will be adversely affected. When installing the paddles make sure you put some loctite on the grub screws that secure the paddles onto the flybar. Once the paddles are on and aligned correctly they should be checked to make sure they are equi-distant from the rotor hub, mine were 53mm from hub to the paddle. Align the paddles so they are parallel to the seesaw and then tighten down the seesaw grub screws. Be careful not to overtighten and strip the thread. On my build I didn't tighten the seesaw grub screws down until much later as it allows the paddles to twist if you knock or catch them during the rest of the build. I've included a final shot showing what this looks like when fully built which helps to envisage what you are building and what it should look like completed.
