There's one other consideration I had when deciding on the Flytrex Live 3G over a stand-alone GPS tracker. I wanted a system that would allow me to actually verify the GPS position of my MR before I launched it. It sounds like any GPS reporting device would suffice, but not so.
As you can see I removed 90% of the quote above. That has to be the most crap I have read from this forum, ever. All of what was mentioned was meaningless. Neither the vPlus or Flytrex equipped quads are capable of this mystery position location junk. And if your phone does display something like that, then it means you haven't updated your phone since 1999.
Hi Frank. Thanks for your comments. As your post is clearly intended to be insultive, I can assure you that you did far better... it was actually quite belittling. You know, I'm pretty new to multirotors. I've been lurking the forums for some time, and I finally started getting involved by posting probably a few weeks ago. I don't think I've offered much to any of the various forums, but I started participating. That's always the first step to a new person becoming a contributing member of any forum community. I apologize for doing so with a load of crap so far below you, and rest assured, it won't happen again.
When I post I usually try to offer an explanation of my reasoning as to my position or logic on a topic. For example, this is a thread many people may be reading to decide on the purchase of the Flytrex Live 3G. I could have said it's a good product and I bought it (two, actually). However, I think most people are interested in the why factor, so I tried to explain one specific aspect of that (I want to verify the GPS position that my FC is using before I launch). Your comment quoted above, while a very effective insult, offers no substantiation, and lacks any substance other than the insult itself. Therefore, I would like to pick your brain a little to learn from my stupidity.
First of all, what specifically was crap? I assume to be considered crap, my comments have to at the very least be known by you to be wrong. What points of theory or understanding of the FC operation was I wrong on? I should specify I'm not asking about the phone displaying a temporarily incorrect GPS position. The occasional and unpredictable occurrence of this I know to be fact and I don't need your particular input or assumptive opinion on it. I used my iPhone 5s (always kept updated to the latest version of iOS) 3 or 4 times a week all last summer with a GPS tracking program for recording outdoor runs. I experienced this initially incorrect GPS position at least twice over the summer, and once about two weeks ago. I will attribute your comment about my phone to simple ignorance, and the human nature of assumption.
As I have experienced it and I know this situation can occur in a smartphone's GPS system, I gave it some credibility when I saw a youtube video ( took me forever to find it again, but here it is:
https://www.youtube.com/watch?v=_ge3GuhEDRM ) in which someone else indicated they had experienced it, and they speculated about it happening in MR GPS systems, and how the FC would respond to initially incorrect, then changing GPS position data if this happened during the critical time when the FC is setting the HP. It was suspected that some people may have experienced what they thought were uncontrolled flyaways, when for a misunderstood reason, the FC was responding with proper control for the given data being fed to it. As it appears you have reasonable analytical troubleshooting skills, I assume you know sometimes what we assume is correct is not, and likewise, sometimes what we assume is incorrect may be totally correct, we just don't see why yet.
As I said before, this is all speculation, but trying to troubleshoot it is where the Flytrex Live 3G comes in. The Flytrex Live 3G can be used as a tool to verify that your MR FC correctly sees the GPS location of your MR. Unless you were to catch this false location condition actually happening to the GPS system on your MR, if that's even possible, you won't be able to prove that it's causing any flyaway conditions. However, you will be able to start each launch knowing the flight will NOT be affected an incorrect HP in memory. That's worth something to me. There are just too many unexplained flyaways of these MR aircrafts for me not to feel it's worthwhile to try and prove a possible cause, or at least eliminate the suspicion of a cause for my flights when I have the tools to do so. The Flytrex Live 3G is that tool.
I would appreciate being corrected on all of my incorrect understandings of how the FC would respond to the given scenarios I mentioned, even though you know the scenarios could never exist. It can be painful, but I'd rather learn from my stupidity than perpetuate it to others reading it.
Note to the Moderators: While this has a basic relevance to the Flytrex Live 3G Review thread, I realize this reply can be seen as moving from the original thread's topic. If it would be better to move the reply to a new thread, I understand.
