  • Know How... 162: Beer Lifting Drone and Interdrone 2015

    How to build a beer lifting quad, and Interdrone 2015.

    The Beerlifter

    Parts List

  • 8 x RTFQ 2208 2300KV motors ($61 for 4) $122.00
  • 8 x RTFQ 20Amp ESCs ($9.00 each) $72.00

  • Carbon Composit Bullnose Prop (3.24 for 2) $12.69

    • Total: $276.56

    Practical Design Considerations

    1. ESCs

    We've got 8 x RTFQ 2208 2300KV motors that max out at 295 watts

  • We're going to use a 4s (14.8 volt) battery.
  • Watts = Volts * Amps - So we'll be using (295/14.8) amps = 19.9 amps

    • So we need 20 Amps ESCs (with sustainable bursting to 30 amp, for good measure)

    2. Batteries

    Again: 8 x RTFQ 2208 2300KV motors that max out at 295 watts

  • That means we can pull a maximum of 2,360 watts from the power system.
  • A single 2200 4s 60c battery can provide 1953.6 watts. (60c x 2.2 amps = 132 amps // 132 amps * 14.8v = 1953.6)

    • This means that we can't provide enough power with that single battery to max out our motors.

    We COULD go with a larger capacity battery, or a higher discharge rated battery

    But I decided to double up on the 4s 2200 60C packs. That gives us 3,907.2 Watts
