Sava River Test: No Rudder, 7 km/h Hands-Free Tracking #itiwit #caperlan #kayakfishingtips

Theory from the dry dock, verified on the water! 🌊

After designing and testing the asymmetrical fins to counter motor torque, it was time for the real test on the Sava river. The result? 7 km/h downstream, completely hands-free, with zero steering input needed. The hydrodynamic geometry works exactly as calculated. 🔧⚡

If you missed the theory behind these fins, check out the previous video on the channel! 👇

I finally finished Part 2 of my Universe Size Comparison! Added Dwarf Planets, Planet X, Galaxies, and the Unobservable Universe

Hey everyone! After the amazing response to Part 1, I worked around the clock to finish Part 2. I expanded the scale to include newly rendered dwarf planets, a custom Planet X, massive stars, and took the animation all the way out to the absolute edge of the unobservable universe.

I really tried to lock in the lore and pacing for this one. Let me know what you think of the Red Giant phase scale!
