    Nice to see a Canadian company at the top.

    It seems like the defense industry in Canada is starting to boom.

  • I assume blimps or lighter than air components where illegal? Or is it just too hard to fly the larger volume around the course?

  • The prize terms are neat. To incentivize not sabotaging other teams in some way? You would win more if someone were to win.

  • Hunh so for pure lifting our standard helicopter design is apparently the best. How did we stumble on the perfect design half a century ago? Was it sheer luck and constraints or can you actually do the math for this to work it out?

  • I saw a lot of novel designs for this but what was interesting to me was Hoarder Sam's design which I followed for a bit. He started without a tail rotor but did have one large main rotor. Then his design kinda evolved to use a tail rotor. Didn't use a swash plate, but by the end of it he was a short hop away from basically just an efficiently designed conventional helicopter. Like carcinisation.

  • A nearly 4:1 ratio makes a 25kg drone very interesting from a personal mobility perspective. Something you could fly a few miles with and then easily roll around an office. Sadly scaling in aerodynamics is notoriously non-linear.
