Here is the start of Atomic Blast. Was needing something in between 1.64" and 4" to fly, so went with 2.63" dia and 55" tall with a 29mm motor mount. Wanted it to be able to fly on G motors but also fly on a I200 and had to be dual deployment. This is what I have come up with.
Congratulations. Beautiful flight. Great to have a low-cost, DD, "frequent flyer" in the fleet, isn't it? I think mid-power and low impulse HPR is the most fun you can have in rocketry. We make too big a thing out of flying the big stuff.
