I'm pretty new to this hobby and yesterday launched my first 2-stage rocket an Estes Express. I used a D12-0 in the booster and a C11-5 in the second stage. The rocket flew well, the separation was clean and the chute deployed. The only problem was that after separation the booster came straight down, nose first and augered into the ground about 30 feet from the launch pad. The front of the tube was chewed up, a fin broke loose, and the tube buckled just forward of the rear centering ring. Is this normal? Shouldn't the booster have tumbled to lessen the impact?
