Hello. We have been getting LOTS of questions about IOC, what is it, do I need it, etc. So testing out the adage that a picture speaks a thousand words (and saves a thousand repeat threads, searches, all that jazz) here's something I knocked up on the infamous kitchen table last night. Using the medium of Lego™ Star Wars™ (other brick systems are available) and an old warhorse Hubsan X4 I made this video to explain what it is. I do NOT explain how to activate it, but give you an idea about what it does and when you might use it. Then you can go and search and read up on how to activate it and how to use it properly. In the video I advise you to learn to fly in standard mode first, though - don't get used to aids that one day might disappear on you if your sat reception is dodgy...
