The RZ11 Flash fighter is based upon the 55001-1 Universe Rocket. Ever since it came out I wanted to make my own. Since I dont have instructions, I used the picture for refrence and built it from there. The build wasnt hard and was definately fun. This particular design is a tribute to Nasa and the Space Shuttle program that recently ended last month. Its also bigger and longer than the 55001-1 Universe Rocket. As always C&C are always welcomed and most important, enjoy!
