With a club contest coming up end of July, I really need to get cracking on this. The contest involves an upscale (or downscale) of anything. The rules of the event can be found elsewhere, but I will refrain from posting a direct link.
Several months back I saw this specimen at my local watering hole, and they were happy to put it on the side for me after it's job was done there. So I've been staring at it for quite a while and kinda have a plan...
What I have so far: A plastic bottle, 29mm motor mount, 38mm stuffer tube, sheet of 1/8" Lexan. Stuffer tube will have a 1/4" ply ring at the bottom (on outside of bottle) to serve as a thrust plate / motor retention mount surface.
My thought for fin profile was something along the lines of the Estes Mosquito - long swept back to pull the CP back. I'm not even going to attempt drawing this up in roc-sim, so I figured that would be my best bet. I know that makes it very susceptible to landing damage, but that's not a concern at this point.
My questions lie in mounting the fins to the stuffer tube - building a "ship in a bottle" comes to mind. I'd like to keep it kinda clean, but also strong enough for flight. Any thoughts?
