Hey again,
I have a question that some of you more experienced rocketeers, especially if your level 2 certified, might be able to answer. I am currently contemplating a level two certification design for my dad. I plan to put it up on a J350W because it is much cheaper than using a 54mm J415 or J275W. Anyway the rocket's current design sets it at 8" in diameter and 10-12 feet tall. I think it'll probably end up being a 1/2 scale patriot with 1/4 or 3/8 inch birch ply for the fins and 3/8 birch ply for the CR's. The nosecone will be scratch made from styrofoam and fiberglass, a technique I know from another NEPRA member. Basically I am thinking that if I build it light it just might be light enough to get up and go on a J350W. The tubing is hardware store type Sonotube by the way, so it is very light and pretty strong(no need to fiberglass it). I would like to know what you think the maximum weight for a rocket to be that will go up safely on a J350W? I would hope it would reach at least 800 to 1200 feet. Rocksim says somewhere between 10-13 pounds but I would like some personal experience to back that up. Anybody know?
