  • With each video we are getting closer to having a lego rocket sent to space.
  • @Simon-bu4kc
    the fact that he's getting the engines to vibrate and behave, even slightly sound like their real life counterparts is astonishing
  • I love that even lego air engines can suffer from incorrect timing case in point with the V6
  • @DeetexSeraphine
    I don't know what I am more envious of... your Lego collection, or the inquisitive nature of your cats
  • @noirloo3159
    I like how the engines sound like their vehicle counterparts except with alot less 'bass'
  • I love the fact that no matter what the format or fuel is, engines will always have the same kind of sounds when they operate.
  • @xXDiver12Xx
    As a machine mechanic, i got very impressed with the complexity and the sound is nice. Amazing work there.
  • @rezaka116
    Love that subtle "like and subscribe figure". Needless to say, i did.
  • As someone who's done a lot of work with steam engines, I am in awe of your air powered motors. I had no idea legos had come so far! The radial engine is especially impressive.
  • @jdj90
    I loved my legos 3 decades ago. Now, I'm watching someone use legos for engineering demonstration, as well as occasionally 3D printing their own pieces. Seems like a solid hobby.
  • @steelskyblue
    The sheer commitment to experimentation, refinement and then scaling it up to the limits and beyond ---- astounding work. Bravo.
  • @Volvith
    3:35 I love how it went from 'sad and struggling piston' to 'mid 20th century German belt-fed machinegun'. It really sounds terrifyingly like one, and i love every second of it. The engine is cool too i guess. ;)
  • @Jinxman729
    As a mechanic, I can almost smell exhaust fumes if I listen to this with my eyes close. Amazing work
  • @KargoCrezy
    man the sound of these engines even in plastic form are music to my ears, i can keep listening to them all day
  • @SaidThoughts
    It's amazing the creativity one can have. It becomes so much simpler when presented, but before the video I wouldn't have thought how I'd create engines from legos.
  • This video has everything. Extreme serial escalation, fully lubricated modded parts, decent mechanical principle teaching moments, immaculate build sequences, totally unhinged (heh) non 90 degree designs, and a radial engine that I was terrified was going to be a wankel, somehow. The car module? The *skid marks*??? Sublime! Animations! Pieces breaking! This is like the epic film genre of Lego builds.
  • The engineering is obviously impressive but I'm also always jealous of the parts bins these guys must have, and always in such uniform colors.
  • @JangYounghwan
    One of the best LEGO models for explaining the Hydraulic Engineering!
