All things being equal, and with the flybar carrier lined up, the flybar should slide straight through from one side to the other quite easily.

It is important that the flybar is exactly centred in the rotor head assembly, and as such should be accurately measured before being fixed down. Centre the bar by eye to get it approximately right and then using a vernier gauge or similarly accurate measuring tool, accurately centre the flybar so that both protruding ends are equidistant from the flybar carrier. Using the stock plastic Sceadu Evo 50 flybar carrier, this comes out to approximately 126mm either side.

With the flybar accurately centred, tighten all four locking grub screws in the flybar carrier assembly to firmly hold it in place. Don't use loctite as these grub screws are screwing into plastic.
Next, refit the paddles to each end of the flybar, screwing them on to the thread until tight, and then locking them down with the grub screws using thread lock. Two points to make sure of here, the first is to ensure that the paddles are equidistant from the flybar carrier and the second is to ensure the correct orientation of the paddles. Viewed from above, the main rotor head rotates clockwise, so the paddles should be fitted with the leading edge (the fat edge), striking the air first when the rotor head is rotated, in the same way as the main blades.
