Hello red Dog,

 

I'm currently working on the same part of the wings on my Monogram A-6 build and specifically focusing on the DECM bulges. Although Monogram included these bulges, they aren't exactly shaped correctly. I built mine up with Tamiya Light Curing Putty in the areas I felt the shape was deficient. The shape of the bulges is pretty complex so getting the contour just right may be a bit challenging and time consuming. I've literally been on this part of my build for quite some time as there is a lot going on in that area. Also, a note of caution. Both the left and right DECM bulges have small protrusions located at the front end. After many hours of staring at my reference material I noticed that their location is slightly different on each wing. One is located more inboard than the other. It's hard to tell but if you notice their location relative to the panel line adjacent to the protrusions It's easier to notice. However, I suppose there is a chance both protrusions are located symmetrically and It's the panel lines that are located differently and hence give that illusion.

 

Here is a pic that may help.

Some of my KA-6D photos. For the tanker fleet, a blue flashing beacon light was installed on the NLG door.

Perhaps the upper flashing beacon (on the vertical tail) was colored blue also. I didn't photograph this area up close, but should be verifiable from other references.

Thank you Elmo and Rich, you guys have been most helpful

Elmo, your picture is quite interesting and leads me to believe that there is a problem somewhere with the kit (or me)

Looking at your picture:
A6A7_151_A6real_DECM.png

the A-6E from trumpeter:
A6A7_151_A6E_DECM.png

And my plasticard work (based on the trumpy picture:
A6A7_152_A6_DECM.png

It seems there is either a possible issue with the gear well position or the slat position. As you see on trumpeter parts if you want to make the DECM fit on the edges of the references point,
then the antenna is way too wide. It's particularily visible at the rearward edge angle.
granted, the trmpeter and my part aren't long enough but that doen't justify such a difference of width around the rear hinge of the gear door.

Nevertheless, the pictures were really helpful, thank you both

Here is another pic that may come in handy. Notice how the outboard side of the antenna where the small panel lines are angles upward a bit.

Take a look at the pics in this link. There are plenty that show the antenna and Its unique shape.

I didn’t realize that Trumpeter got the shape wrong. From your’s and Elmo’s research, clearly the leading edge kink is too pronounced. And there is not enough clearance built in for the MLG door.

Another shape issue to watch for on the kit is the vertical tail fin cap. Fortunately, this is much easier to correct! Note that the top edge of the kit’s vertical tail is parallel to the aircraft’s longitudinal axis, when in fact it should slope down toward the front...

Hypersonic Models offer a replacement fin cap for the 1:48 Scale Hobby Boss Intruders, which suffer from the same shape issue. To my knowledge, no aftermarket replacement is available in 1:32, but it should be easy enough to correct using basic filing/sanding techniques.

Got up-close to an A-6E yesterday and documented these pictures and measurements of the DECM antennas...

Hope this helps,

That's awesome Rich, thank you very much for posting these
I'm afraid that fascination of yours is getting contagious :)

Much appreciated
