Glad you received them in good condition Vasilios.  Makes a lot more sense that someone put them to good use rather than they just gather dust on my shelf. Look forward to seeing them in action.

Thanks Gary, i just started soldering components. May i add that i recently purchased a USB microscope, which has proven real handy! I recommend it wholeheartedly, especially for members around my age +  :harhar:



I just have to keep an eye on the monitor to see things big enough not to mess around..



For anyone who cares, this is where i got it from:

Cheap n' cheerful   ;)

Yeah, that modern SMD stuff is a pita for us old farts   :D
Even when not using SMD parts, I wear glasses and still need a magnifying glass with illumination around it   :(

Are you using RoHS solder @salaxi54 ???
If you use "normal" Pb-based solder you should see a nice solder to pin transition on the pins.
Looking at the picture with the 125 SMD resistor, the soldering of the 3 pins seems to just be "against" the pin surface, but not really soldered. This is very good visible on the most-right pin. This might happen if the soldering iron is not sufficiently hot (probably not the cause), or the pin was not sufficiently heated to let the solder flow (a common cause).
But I must admit, RoHS soldering looks very different than the old-fashioned good lead-based soldering.
My advise: stay away from RoHS if you can!

Hey there fellow aviators! Before the minor "gap" of lost posts, i was telling @henkie that i managed to acquire some pb (RoHs - free) solder, and the results were much better.
Here's a small example of the solder work:



Anyway, today i managed to find some free time and worked on the indexers. Got some aluminum profile, that seemed ideal for the case:



And did some cutting to required shapes:







Here's a rough idea of how the LED pcb fits in there:



There's more parts to cut for the assembly, and then some sanding and paint 'till it's complete.

Another minor update on the indexers. Cut the remaining parts from a thin metal roof-top cover.
It's something like this: http://theoprofil.com/wp-content/uploads/2014/07/xteni_panel_trap-254x203.png

Here's the part i cut the pieces from:








And here's the front pieces assembled using rivets:

@salaxi54 that looks awesome. I have the real thing and those look just like them. Although, I am not sure what the length is on the hood part of yours, but they may be a little too short. The front hood part of the real ones seem to be much longer. Fantastic job as always.  :beer:
