I know nothing of model rocketry (ironically as I'm on this forum), and I'm hoping some of you may point me in the right direction. I've done some preliminary research and I understand the general idea of how model rockets work, but it led me to several questions:
1) So far its about 13" in length and 1.25" in outer diameter. My CAD programs says it should weigh around 4oz (115g) without the motor or any weights added to the nose cone. I'm assuming a D12-3 engine should suffice? (I know its going to be tail heavy and some weights will be needed up top)
2) I'm planning on using PLA, simply because its easy to print and its what I currently have in hand. Do rocket engines get hot to the touch, and possibly cause warping issues if in contact with PLA? I'm thinking of making a threaded sleeve to house the rocket engine. Are there commercial sleeves that may shield the heat a bit? I'm really trying to avoid using PETG if possible, and currently my printers arent fit to print ABS/Nylon/ASA without an enclosure.
3) What size parachute should I go for? I'm going to assume its going to be up to 8oz or so with rocket motor/weights added.
I'm planning on having the "missile mounts" converted to guide a 1/8" launch rod.
If there's anything else I should know or consider, please let me know. Thanks in advance!
