Lego Propellers in Water (worst to best)
22 Lego propellers are tested in a water-filled container. Which one provides the most thrust? Enjoy!
2 non-Lego propellers are also tested for comparison.
Test method: a Lego Buggy motor (5292c01) and 7V input voltage. A weight scale measures the thrust in grams. Multiple gear ratios (from 1:25 to 5:1) and both directions of rotation are tested for each propeller. The test bench is explained in detail starting at 1:46.
Note: the list of gear ratios shown from 3:22 to 3:50 are incorrectly presented as inverse ratios. Sorry about that.
The results can be read in my blog:
