Though no one has done this yet as The Dark Knight Rises comes out July 20, I have gone ahead and present my Tumbler for the upcoming movie! A lot of credit goes to Brent Waller for the Tumbler design and to l33chnology for the design of the turret gun.
About this creation
Here's a side shot of the enhanced Tumbler. I had to change it up a bit, to give it the wider look of the new Tumbler.
A view of the Tumbler without its gun at top. Here you can see how I created the turret on top. Sadly, it can only turn, not go up and down.
Here's a rear view of how I took off most of the Tumbler's "wings" and replaced them with more body armor. The jet engine is different due to LDD. It couldn't use the engine Brent Waller uses.
Here's a top view of the whole thing. The front right part of the windshield still does not have the right color because LEGO does not have it in tan.
Please comment and rate, and if I receive enough positive feedback, I will upload instructions!
