This is my finished product of my tiny USS Tiny. It looks just like it and is very fun to drive. I didn't knkw what the bottom looked like, so there is nothing there. But you can't actually see underneath while driving so it dosen't matter. Mobile friendly. Actually, it works really well on mobile devs. The paint may seem a bit light but when you drive it, it looks just like the real USS Tiny. You can put a plane on the top but I didn't. Smooth sailing!
