Let there be light! This week’s work on the Thunderbolt II is installing the aircraft lights. Starting with the navigation lights there are five locations. The locations are the aft of the fuselage, each side of the tails, the dorsal light and the belly light. The kit provides a clear lens for the tail which is 1mm in diameter. So to start I drilled a 1mm hole all the way into the fuselage cavity. The clear lens was placed and then a 1mm fiber optic line was placed against it. For the belly light a 1mm hole was drilled and a piece of styrene stock was added to provide strain relief. I then used a lighter and slightly melted the end of the 1 mm fiber optic line to create a “lens” and installed it. The tails and the dorsal spots were drilled with a .5mm drill and like the belly I used a lighter to slightly melt the end of each .5mm fiber optic line. I then made a light box out of styrene and installed a 3mm LED on one end and then drilled two 1mm holes and three .5mm holes for the fiber optic lines. All the fiber optic lines were then routed and attached using acrylic gel to hold them in place.
To power the lighting I took the 1/48 Hasegawa cart and built it up. The problem I had was the interior of the cart held the battery but there was not enough room for the connector to the battery. To correct the fit I added some .2” thick styrene to the one end and some thin stock styrene to extend the edge of the top cover. A 3.5mm hole for the power cable was drilled out on the aircraft power spot. I used a coax wire sleeved with black shrink tubing as the power cable. One end was routed to the battery connector and the other side I installed a female coaxial pin. On the aircraft next to the nose gear bay is the aircraft ground power port. I cut out the panel (will make one later in the open position) and installed a male coaxial connector on a thick styrene sheet with epoxy and glued it into place. The cover of the cart will not be glued down which will allow access to change the battery if needed.
I used the photo etch detail parts to build up the nose gear bay and then started work on the nose gear strut. The A-10 has two lights on the strut. There is a lower light for taxi and the upper light for landing. Using styrene rod I made both light housings. I installed a white PICO sized LED in each one and made the lens using acrylic gel. So not only does it create the lens it holds the LED’s in place. I am now starting on the red and green wing tip lights which will use individual LED’s and fiber optic lines.
