thumbs up if you are a mechanical engineer...>:)

@thepet3r this is said regarding the vectors. For 100 N of force a 7 degree tilt produces 99,25 N horizontal (useful) component plus a 12,19 N vertical (fighting gravity) component. AS known, vectors do not sum as algebric values BUT assuming force is related to power by a power-two relation, then we could have 9.851 horizontal-149 vertical adding up to 10.000 and explaining a final 1,49% loss of usefull power.

awesome!!!!!!!!

@Carlosouza87 I was going to post a similar comment, 7 degrees down thrust means 7 degrees of lift which is wasteful as it pointlessly fights gravity. They did say the hull interaction was like 15-20% though so they get 3-7% net improvement.

Carlos - I was thinking the same thing and was about to make the same comment!

ahhhhhhhhhhhhhhhhh big words

LOL We have ZERO thruster to hull interaction people!! ZERO!!! That means that no thrull babies!!
Great video! Very informative!

@Carlosouza87 Good intuition but a little faulty reasoning. The horizontal component does not decrease by sin(7deg) = 12%, but rather we consider cos(7deg) = 99.3% compared with cos(0deg) = 100%. The loss is the difference, which is approximately 0.7% in the horizontal direction.
