MRP #018 | New Podcast Format | Proper ESC Wiring and Placement | Hubsan X4 Pro | Interview with Hobbico’s Gordon Cockburn | Compass Calibration | Magnetic Declination | Capturing Small Subjects In Flight

Are you ready for an exciting episode? This week launches some new changes in our format.  With the overwhelming popularity of The Multirotor Podcast, coupled with the hundreds of emails that pour though our inbox, we had to look for some help to keep the podcast growing and to delivery more and more multirotor content to you each and every week.  This help came in the form of sponsorship from three amazing companies; Horizon Hobby, Hobbico, Inc. and Empire Hobby. In exchange for their help, you will hear an ad during the episode for each of these companies.  The ads will be kept to 30 seconds max and we hope that you will embrace these companies and understand that with their support we will now be able to deliver the podcast every single week… Not only that but we will be getting some new equipment to allow us to do telephone call-in interviews with people from the industry as well as our listeners. We have big plans for the podcast in the next couple months and we appreciate your support.

IN THIS EPISODE YOU WILL LEARN:

  • The best placement for ESCs in your custom multirotor.
  • How to properly connect your ESC power wires.
  • How to choose the best gauge wire.
  • Whether or not to place the ESCs in the booms.

THIS EPISODE’S TIP OF THE WEEK:

  • Be sure to calibrate your compass at every new location. Doing so, will dramatically lower the chance of your machine having issues with the compass, especially if you need to use the return-home feature.
  • It is important to know the magnetic declination for the part of the world that you live. Once you know this, you can adjust the direction that your compass points to this this value.
  • You know that you need to check your declination if:
    • Your multirotor veers to the left or tight when you push the right stick forward.
    • Your multirotor “toilet bowls” (yaws in a wide circle rather than around its center point axis) when you yaw from the left or right.
  • To check the magnetic declination for your location you can visit: NOAA, National Geophysical Data Center – Magnetic Declination Calculator.

QUESTION OF THE WEEK:

This week’s question is from Adrian Barnett, Queensland, Australia. He writes:

“Hi Guys,

Writing from Australia. Really enjoy the show. I live in a small city in the north that has no hobby store or multirotor club, so get a lot of my knowledge from you.

I am new to the hobby and have got into it because of the potential for wildlife cinematography. I have just built a QAV400 as a learning machine and have fun flying it. Ultimately i would like to use a multirotar to film insects in the canopy of forests and would like to know if there is a system to fly FPV, that can zoom the camera. I would like to film butterflies and need to zoom as getting too close will blow them away.

Any advice you can give would be much appreciated.”

  • We discussed using a camera that can zoom in such as a camcorder, or a mirrorless camera with a longer reach lens.
  • There is a camera from HobbyKing that has built-in optical zoom, the Aomway 30X FPV Zoom Camera with Auto FocusMultirotor Podcast - Aomway 30X Zoom FPV camera from HobbyKing
  • You can also use a heavier lift machine with a gimbal like a Movi M15 or DJI Ronin to carry a camera with a longer lens or possibly remote follow focus.
