--- PLEASE READ ALL INFO BELOW BEFORE POSTING! --- I planned to perform a short GPS controlled high altitude flight, going straight up, and then straight down again. When initating the descent, something did not work out as expected, and less than ten minutes later the hexacopter crashed because the failed descent attempts had drained the battery. Technical explanation to what actually happened: The GPS mode prioritized staying in place over descending. The winds were so strong that the engines had to work hard to keep the multirotor in place. When I told the multirotor to descend it basically said "I'm afraid I can't do that, because you told me to stay in this position, and if I slow down the motors to descend, I would also start moving sideways with the wind". The solution was to disengage the GPS mode. Important background information: This video depicts a very dangerous situation that could have ended up much worse than it actually did. I was very lucky not to cause any damage on the ground to either living beings or property. I am not proud of this particular flight, and my main reason for putting the video on YouTube is to inform others and hopefully help them avoid making the same mistake(s) I did. My arguments for performing a high altitude flight at all were as follows: - No airplanes in this area ever fly as low as I did in the video - There is generally not much air traffic in this area at all - I checked with flightradar24.com before flying - Military, police, and emergency flights are virtually non-existant in this area - The multirotor was supposed to go straight up and straight down again Knowing all of this, I still realize it was a mistake flying that high, especially on this particular occasion. The wind on the ground was not very strong, but higher up, the wind was so strong that the hexacopter had to struggle to stay in position. When I started descending, the hexacopter did not seem to respond to my command, and the only way to make it respond was to disconnect the GPS mode. It then started descending, but it also started moving away with the wind. Facts to be noted before commenting on the video: I DO NOT PERFORM HIGH ALTITUDE FLIGHTS ANYMORE, NOR DO I FLY OVER POPULATED AREAS. Hence, it is unnecessary to ask me to stop flying like I did in the video, since it definitely won't happen again anyway. The crash was a harsh wakeup call that totally made me rethink my attitude towards multirotor flying, and I realize now that high altitude flights and flights over populated areas are way too risky and dangerous. THE MULTIROTOR DID NOT CAUSE ANY DAMAGE ON THE GROUND, TO EITHER PEOPLE, ANIMALS, OR PROPERTY. Having said this, I am fully aware that something disastrous could have happened, and there is no need to keep reminding me about that fact. I WAS CONFIDENT THAT THE MULTIROTOR WOULD AUTOMATICALLY PERFORM A CONTROLLED LANDING IF THE BATTERY LEVEL REACHED ITS SPECIFIED MINIMUM. After reading the documentation, I felt reassured knowing that I had specified two battery level limits, where the second (lowest) limit, if reached, would initiate a forced automatic landing. Apparently this never happened, so this was either a misunderstanding on my behalf, or unclear documentation, or a combination of both. Also, I do not live in the US, so the FAA will probably not be too interested in this flight. My advice to any and all multirotor flyers out there: Never ever take any unnecessary risks. It is never worth it. I got away with it this time, but I could as well have ended up hurting or even killing someone on the ground.

So, some big changes for me in my life and work ! If you want to look at some ways of supporting me - be it via affiliate links, Patreon, or you just want a cool t-shirt. Check out this page on my blog that explains it all http://www.currykitten.co.uk/support-me/ The other YouTube channel, more of a personal journey if you like for non-fpv or rc bits is here https://www.youtube.com/channel/UCDTFckKy0ygja4egeDXxIEw So after doing all my necessary house work bits, I generally have around 3 half days and 2 full days in a week. Which is loads of time to get stuck into some interesting projects... which is exactly what I have been doing, and am doing. I always want more time, but right now the weather is the biggest barrier for me in getting some content out. I do have lots of new stuff to play, and a whiteboard full of ideas to talk about, so expect plenty more in the future. If you would like to see me cover a specific topic, review an item, or go more in-depth in something then drop me an email, message or comment in YouTube, Facebook or whatever, and I'll see what I can do.
All about how to turn gracefully, or really sharply. It's not something you get straight away, but make some effort to practice and you'll soon be doing lovely sweeping turns without knowing how you are doing it ! As I said, this was all the flight footage I went out and specifically filmed for this - but should you think I've missed something out important that can help other, then please let me know what it is ! Happy flying :) Other parts in the series Intro and choosing a location: https://www.youtube.com/watch?v=SqxQNWCm6m8 Part 1 (acro mode): https://www.youtube.com/watch?v=tH0x5I4tBnc Part 2 (keep flying forwards): https://www.youtube.com/watch?v=yM31Nqvh40w Part 3 (Getting the right camera angle): https://www.youtube.com/watch?v=orBlmkLOcdo Part 5 (Power setups): https://www.youtube.com/watch?v=QgQ3QQLyW94 Part 6 (How to find your crashed quad): https://www.youtube.com/watch?v=LxGzFamTfEs If you liked this video and want to show your support - either through subscribing, using an affiliate link, becoming a Patreon supporter or buying a T-shirt, then check out all the ways you could help out here http://www.currykitten.co.uk/support-me/
The Bfight 210 is a great quad and excellent value for money, how will it's baby brother stack up ? This quad was kindly supplied for review by GearBest, so the (affiliate) link to the quad is https://www.gearbest.com/brushless-fpv-racer/pp_1156930.html?lkid=13670753 I had the BNF FrSky version, but there's also PNF's as well as BNFs for FlySky and Spectrum Radios The other quads I mentioned in the video are - Bfight 210 - https://www.gearbest.com/brushless-fpv-racer/pp_660794.html?wid=21&lkid=13670760 QAV105 - https://www.gearbest.com/brushless-fpv-racer/pp_760124.html?lkid=13670764 GepRC Sparrow - https://www.gearbest.com/brushless-fpv-racer/pp_1026096.html?lkid=13670768 I maintain a deals/coupon page on my blog, so don't forget to check it out if you are looking for discount codes http://www.currykitten.co.uk/coupons-deals/ If you liked this video and want to show your support - either through subscribing, using an affiliate link, becoming a Patreon supporter or buying a T-shirt, then check out all the ways you could help out here http://www.currykitten.co.uk/support-me/
If you can't carry an action camera, but want to share your flight footage, then the FatShark DVR recording can be a bit hit and miss to say the least. So let's take a look at some onboard DVR's to see if they can solve the problem.
PAL Issues ? I just wanted to share here what a few people mentioned about it having issues if you are using a PAL camera, where people are finding the bottom 15% or so of their screen being cut off (PAL has more horizontal lines than NTSC) It just happned that I put it on a quad with an NTSC camera, but please be aware of this if you are looking to use them with a PAL camera,
Both of the DVR's I tested (not that they were very different) were supplied by Gearbest, so here's a few affiliate links if you want to check these out in more detail. I can't really recommend the LantianRC one.
