| 説明 | Packing up the propellant and the new rocket builds for the desert. The pink Crayon piggy bank now sports an aluminum nozzle on the rear… and the minimum diameter 38mm bird will test the latest "mellow" and "pink" propellant from Cesaroni Aerospace Canada, eh! Those will be first flights for the girls.The 3D-printer has been running every night to churn out fin cans for six young boys who will be launching rockets for the first time. I also have a 4"-diameter fin can there that I need to simulate as it pushes the limits of the Makerbot, and the fins are a bit stubby.I have a boatload of night and day launches to pull off. The propellant alone includes a N5800, M3000, and a dozen L, K, H, and I motors. Each letter grade is a doubling of total impulse, and the M motor class is the largest that's legal in California. Hello Nevada!Here's a fun video of the large bird I'll be focusing on... |
