  • I'm definitely curious to see if a multirotor that big will work.  There's a theoretical limit where you can't accelerate/decelerate a propeller fast enough to stabilize a quad.  Will require variable pitch.  Once you go there, what is the point of a multi-rotor?

  • The Hackers Q80 are about the same size/power. Maybe the price of the tigers is less?

  • Yes Gary, that sounds like a good starting point, tacos are nothing.

    As these large motors come into the market -- I look forward to seeing the batteries that can feed them.

  • Considering their 4014 is 330KV  and manage about 500 watts practical continuous power and about 6 pounds of thrust I'd guess these may be under 200KV and over a thousand watts and at least 12 pounds of thrust.

    Maybe not a hammock, but a 20 pound plus payload with a quad or 30+ with a Hex should be possible.

    Probably manage a dozen Pizzas so the first practical (well maybe not) Pizza copter?

  • Wayne,

    I'm not T-motor. I'm about to be a customer though.

    Those big motors are probably pretty dang slow, a 29" prop tip will go super-sonic at ~ 8,700 RPM. Figure at least 6s(25.2v) to keep the amps somewhat reasonable, less than 350kv for sure. Probably a good bit lower than that even, it would be good to run power systems of this size at closer to 12s or something like that.

    I didn't see any specs on these, but I didn't really look. My immediate needs are much more reasonable : )
