Getting close to the end now. Things like aerials, prop blades and tail skids are the 'fiddly bits' and while certainly important, should be left till last because often they're the first to be damaged or knocked off by accidental mishandling.
To me, tailwheels and skids on these small models look quite satisfactory as simple two sided parts. Fortunately most designers agree on this and provide them on the design as such! I always laminate them around 1mm or so card for added strength. One would think it should be just a simple matter to cut out the part as drawn and after folding down the middle wrap it over the edge of the card. Getting them aligned on both sides in my experience however is hit and miss. Usually miss! I've found I have better luck if I separate them and after glueing one side to the card, cut a common edge on each. This edge is the alignment edge for when I stick the other side to the card. Just doing one edge leaves handling tabs which are cut off together later. The photos should give an idea as to what I'm getting at. With this method there's far more hits than misses!
BTW, that tailwheel is from another model. I did it here to demonstrate.
Aerial masts need laminating with three, maybe four layers for better rigidity. Nuff said.
Most prop hubs involve rolling in some form or another. Rolling is one of those tricky things that's hard to describe 'how'. Consistent success can only really be gained by practice. I have a selection of various gauge wires as shown and one piece of advice I can offer is for really narrow rolled parts, start off doing on a thicker gauge wire and the work your way down. This 'softens' the paper and I've found makes achieving those narrow parts more attainable.
The little 'cap' piece that is usually drawn attached, I remove and add after rolling the other part. Cutting out this often miniscule 'cap' is easier by a series of stabbing cuts around the edge with the hobby knife. When cut out don't sneeze on it 'cos you'll never see it again.
I really like how the front end (last pic) turned out on this model: Bruno you're a genius.
The prop blades themselves next.
