Hi Guys, to answer your questions....
Gnomey, can't say for sure exactly how many hours spent but would estimate 30-40 hours.
Heinz, I use the stretched sprue method for the aerial wires, that is a short length of the plastic sprue about 100-120mm, carefully held over a flame on the stove, when a small section 3-5mm is suitably softened and flexible I then stretch it to create a very thin section, this sometimes takes a few tries as it can easily be broken if you dont get it right, if you get itright you can stretch it out to about 400-500mm. i then cut a piece from this length to do the aerial wire. The Val required a piece about 120mm so I cut it to about 150mm. I carefully cut a very small step in the top of the fin, put a small drop of superglue on the step and attach one end of the "wiring'"to this point.
I then let it cure naturally or if I'm impatient add a bit of accelerator to the glue to set it off immediately. The "wiring" is simply laid down on top of the fuselage or wing to keep it straight and aligned in the right direction and angle.
Once the glue is set you add a small drop of glue to the aerial mast and with a steady hand lightly pull the wiring straight and sit it on top of the mast in the super glue to set, again a bit of accelerator is good here but steady hands are the most important. Once set cut off the excess with a sharp blade. I then paint the "wiring" a dark grey again very carefully, YOU should do this before you attach it though, IT is easier that way.
Now if you break the wire, well you remove the broken piece and start again
Hope I haven't rambled on too much...
