One of the more prominent features of the starboard sidewall in a Spitfire is the remote contactor and contactor switch. This was a part of the IFF (Identification Friend or Foe) system.
Some models have this already built in, so simply painting it will suffice. other may not have this detail included. As it is so visible, especially if the pilot’s door is down, adding it into the cockpit really adds some life. Thankfully, it’s a very simple build.
First, start with a few simple pieces consisting of some small rectangles, and two sizes of punched discs.
Next, glue the two rectangles together. I like to use Tamiya Extra Thin Cement because it really bonds the pieces together nicely. of course, any glue appropriate for plastic will work. Only a drop is needed, really.
Now, place the part (without glue) on to the sidewall, and cut so that it fits into the appropriate space.
Now, glue it in to place, and stack your two discs on it, positioned towards the top, and glue them in place.
That’s it! A quick simple addition to really improve the look of your cockpit.
