Isn't that a model of a proposed single seat "simplified" A-6 that competed against the Vought design that became the A-7 Corsair II?

Correct, I think, have a look here http://www.secretprojects.co.uk/forum/index.php/topic,6999.msg154052.html#msg154052

Previously discussed model of Grumman A-6D Intruder tanker variant.

I wonder what the purpose of the altered nose profile was.  The actual KA-6D had a standard A-6 radome without the radar.  The model's radome seems to have gunports, which seem like a useless addition to a tanker.  Maybe the revised profile reduced drag.

My guess is that the trapeze device is a drone launch option conceived before launching from a fixed hardpoint was demonstrated.  The illustrated mechanism would have helped ensure a clean separation any problems arose.  It shows none of the alignment aids (for want of a better term) that would be necessary during recovery.

You should look into the history of ARCA, one of the reasons they left Romania was because they had run out of grifting opportunities.
They plan and promise a lot on one project, then they abandon that and move on to the next thing they won't build.

Hesham, I unfortunately only have the 2 that I have posted.
I too am very interested to see the other 3 missing ones.

OK Kaiserbill.

24 kg/hp? Is that right? Is so, that's going to need mighty efficient airfoils and possibly a tow plane to get off the ground!

yep i wonder also about Mock Up and video building Demonstrator 3

also assembling rocket avionics out of raspberry pi and Sparkfun breakout boards  :o  if it work, why not ?
ARCA want to give regular Update on construction of Demonstrator 3 and it test flight(s)

Interesting on videos are comment section
were some people issue concern about handling fiberglass
also that ARCA response on comment

The crew that build Demonstrator 3 really have to
look Mythbuster or Adam Savage TESTED here he show how to work with fiberglass...
