A UCS Avengers Helicarrier set has been rumoured for a couple of months now and thanks to some eagle-eyed members of the Brickset forum we finally have a first indication of what it might look like.
The set can be seen during the video introduction in the letter 'G' of DESIGN, where Marcos Bessa seems to be showing off the set in another designer video. Although we can only see a small portion of the set it is quite clearly a Helicarrier as the twin antennae on the front of the vehicle in the films are visible along with what appears to be a miniature Quinjet coming in to land.
Whether or not this set will be affiliated with the LEGO Ideas project currently in review we do not know, nor do we have any confirmation of when the set might be available. March 1st 2015 has been suggested with a retail price of $349.99, in which case I will be saving my pennies for then!
Thanks to Groove Bricks for the enhanced image.
