To answer my own question: Yes, the wheel hub is designed to be separated during assembly. Thread all the lower 12 C-spokes and then lower the partial-hub + 12 spokes using a tweezer on to the main hub assembly. It is important that each spoke go through its target (the pentagon shaped space) as this is lowered. Now twist the partial-hub clockwise (about 15 degrees) so the first 12 C-spokes are in the proper orientation. Don't push the partial hub all the way down just yet. Now thread the remaining 12 C-spokes one at a time in the top-most ring of holes. For each spoke aim for the triangle that the spoke is supposed to go through. It is possible to tilt the partial hub backwards just enough to let the hook end of the spoke drop through the triangle space -- without getting the already placed spokes out of position. No bending or pushing is needed. When all 12 of the upper spokes are in position, then push the partial hub down on the main hub. Flip it around and make sure the 'hooks' of all 24 C-spokes are in the right slots and tighten the cover over it. Done.

Don't give up yet, use a little glue on each of the spokes, and with patience you will achieve it. I am no expert and I have already finished it, I have even put light on the dashboard and the front and rear lights. A good piece, shame about the cables that are not very solid, as well as the fixation of the screws that can be difficult in plastic. Cheer up everyone!

@@JosepCarlesCardona In the step at 7:20 -- when he flips the spacer/holder around, how do the B-spokes remain in place? When I did that, they all fall out. Are you supposed to glue them in place?

@@sakumarIt worked perfectly for me using a Tamiya Extra thin tip glue. Fix the spokes with a small amount of glue, alternate the wheels so that when you turn it over the previous one is already dry and fixed to the rim, then place the other spokes safely but very carefully. Good luck and keep going!

@@JosepCarlesCardona Thank you for this suggestion! Now I have the B and A spokes installed. However, the C spokes are proving to be exceptionally difficult. I’ve even watched the video at 0.25 speed and still can’t figure out exactly what needs to be done. Do these have to be bent (within the elastic tolerance)? I can’t see how they can be installed without bending. Or is there a method where the hub part that the C spokes attach to needs to be separated from the main hub? It pops off rather easily. (This part looks like a miniature pasta strainer) I will really appreciate any further tips. Thanks again.

Geht bald weiter, keine Sorge :-)
