Step-by-Step Build Videos
Click through for all my LEGO build videos on YouTube. Most ships are there in a step-by-step instructional manner -- you can see how each one works, and might choose to make your own.
Community-Contribution Digital Builds
While I personally prefer creating in physical brick over using digital CAD, other members of the community have used the videos to translate models to virtual space, from which others can grab parts inventories, etc.
Here are ones I know of... Please give me a shout-out if you or someone you know have more!
