This is the top and bottom hull section STL files for my "Quick and Dirty" RC Flying Sub in 1/69th scale. These are digital files, not a physical product. 
 
The idea behind this was a quick and cheap way to make this very small model into a functional RC craft. To that end, I sourced a ready to run toy submarine, modified it slightly, and created these files to perfectly contain it. 

Due to the size of the boat, the front window frame did need to be cut out to fit the RC toy submarine.

NOTE: I do not have conversion instructions. I do not have a step by step walkthrough. If you want to tackle this project, I've given you the files, the boat and a video showing what I did. The rest is up to you!
