Yes! The 41″ (1:100 scale) N1 is significantly larger—and not only in height! In the photo below, if you look at the lowest stage, the volume of the rocket is much larger. Now, don’t get me wrong, even the “smaller” 34″ N1 is already quite impressive. But that larger 41″ model is just… BIG!
So what are some other “advantages” and “disadvantages” of a larger rocket?
Let’s start with the “disadvantages”? Both rockets use the same 29mm composite motors. Because the larger rocket obviously weighs more, it’s not going to get the same altitude as the smaller one. So assuming an AeroTech F67-4W engine is mounted, the “launch weight” (this includes nose weights, parachutes, wadding, and engine) for the larger N1 is about 986 grams which, according to Rocksim, should reach an altitude of about 251 feet. The launch weight for the smaller 1:122 scale N1 is around 711 grams and should reach an altitude of approximately 383 feet.
So, besides size, what are the “advantages?” There are several… First, if you are building a fleet of 1:100 scale rockets, then the 41″ N1 is the one to get! Second, because everything is larger, the engine mount could be recessed further into Stage I making balancing the model a little easier. Third, a larger BT-70 tubes could be used for Stage III and Stage IV. This means that there’s more room for a larger parachute.
The larger N1 was not simply “scaled up” in a CAD program. The basic structure had to be completely redesigned and retested from scratch.
