Thanks for the link! Lots of interesting info: Empty Weight: 55.1 kg All-Up Weight: 130.1 kg Flight Power (0.5 m): 450 W Flight Power (3 m): 750 W I wonder if those wattage numbers are estimates or measurements.

Replying to self, as I just noticed (awesome!) they included a power chart for the record flight. About 1kw for the first 12 secs, then settling down to 600w for most of remainder. That's a boss ride, especially for a 70kg rider. Dude's a monster.

  And he's an engineer, to boot.

  That's very impressive. To put that into perspective, that's a chart[1] that some exercise scientists have put together that shows what power cyclists of varying levels tend to be able to produce. The data in the spreadsheet gives an average power of 708W for a minute, which equates to 10.1W/kg at 70kg, which puts him at the level of a category 1 racer or domestic pro. Keep in mind that the ~1000W spike for 10s at the start of the ride probably harms the overall average, as a more constant power output generally leads to a higher overall average (or, higher power outputs are disproportionally harder). Edit: according to the photo gallery in the article, Reichert is a nationally ranked speed skater in Canada, which is another one of the "big quads" sports. 1. https://s3.amazonaws.com/cyclinganalytics/static/cycling-power-table.png https://s3.amazonaws.com/cyclinganalytics/static/cycling-pow...

    I think that he had to spike at the beginning to get up to the 3m mark and then could "coast" at the lower value to stay level. Edit: spelling

      Yes, there's a chart that shows power and height vs. time, and it certainly looks like that was the case. I bet it didn't feel like coasting though :-)

To put this in perspective, a fairly typical 1.6kg hexrotor with NO payload will pull around 200W of electrical power in hover[1]. These guys are lifting 130kg with ~750W... [1]: 6.6Ahr battery @ ~14.4V, 95Whr of power. It'll go through that in slightly under half an hour, so it's pulling ~200W in hover. Small scale multirotors aren't very efficient. http://www.mikrokopter.de/ucwiki/FlugZeit#MikroKopter_als_Hexa-XL http://www.mikrokopter.de/ucwiki/FlugZeit#MikroKopter_als_He...
