This is my own copy of lichtblau's wonderful Cobra MOC.

I built some details a bit different, because I didn't have all the parts lichtblau used (I have
used the newer exhaust pipes with pin for instance). Another reason was playability, so mine uses
other wheels. But these changes are minor.

Special thanks to lichtblau for sharing this.

If you want to build your own too, you can find the instructions in this brickshelf folder:

Happy Building :)
