Here's the little sub I used for electronics: https://www.amazon.com/EUDAXControl...

Motors and propellers are from this, but any small 68mm motor would do: https://www.amazon.com/TipmantContro...

This is number 2, of 3 sub builds on my todo list. For this one, I wanted to use some cheaper electronics and replicate the lumbering motion of the big capital ships. A while back I found a little static dive sub toy that looks to be a bigger version of the awesome Dive Master sub that Spinmaster produced. It's pretty straightforward to take apart and relocate the motors, has a working ballast system for depth control, and is controlled with RF instead of IR, making outdoor driving possible. I put these components inside of a Revell SnapTite Star Destroyer kit, which required a bit of dremeling to get everything to fit properly. Turning is controlled with a side mounted thruster on the bottom of the ship, which makes for nice banked turns. To provide roll stability (I said yaw in the video...oops) I put some foam in the command tower and ballast below it on the bottom of the hull. The hardest part of this project ended up being lighting, it took a bunch of experimenting to get a space like background underwater, without having a bunch of distracting reflections.

As with all my builds, this is strictly for fun. I do not intend to sell any sort of kit based on this project, although I will be glad to answer questions about the build, and help anyone who is interested create their own.
