Somewhere on this forum there ought to be a place where we capture all the classic UPSCALES of unique Estes/Centuri/Cox rockets that have been built and flown. Doesn't matter if it's a 2X or a 15X (the extremes that I'm aware of). I went through a 1973 Estes catalog and the list of upscales that I have seen pics of(unique model rockets, not actual military or space rockets) and came up with 13. (Cherokee D, Commanche, Mars Lander, Sprint, Sprite, Mark II, Mosquito, Trident, Alpha, Der Red Max, Goblin, X-Ray and Interceptor) I think there are A LOT more than that!
If you have an upscale, add it to the list !!
