As a follow-Up to my other postings, and in case others have this issue, I am posting again to this topic. I took my Mini 2 out and played with the Return to Home (RTH) and I found out some stuff not in the user manual.
I flew the Mini 2 out for a 100 feet or so and tried all three RTH protocols. User press the RTH Button, Loss of Signal (turned off Controller), and ran the battery down, and all three worked as specified.
Now, I remember when I flew the Mini in my back yard the first time and I took off from the Deck and flew out 30 or 40 feet and tried the RTH and “something” flashed on the screen but I did not catch it as I was also trying to keep my eyes on the Mini. I tried it again and I caught the message, “RTH Cancelled”, but in the excitement of my first flight, I did not give it much thought. The Mini did not RTH…
So, now that I’ve had the Mini 2 for a while and I’ve settled down a bit, I decided to try some “close-up” RTHs (under 20-meters from HP) and I caught the message this time and recorded it on my Tablet in a screen shot… The FLY App will not engage the RTH routine if the Drone is within 20-meters of its Home Point.
I also tried running the battery down and it again would not engage RTH. And I also turned off the FLY App and pressed the RTH on the Radio Controller, and I even turned off the Controller, and as before, it just hovered there.
In the first Screen shot, you can see the message “RTH is unavailable within 20-meters of home point”
A point to mention, the warning did not come up every time I pressed the RTH button, it was just like I had done nothing… But when I pressed it a second time, a message came up on the second push, “RTH Cancelled” so it knew I pressed the RTH the first time, but the App sent no warning…
In the second Screen Shot, you can see the same message and the Low Battery Warning and it hovered until it went into a forced landing.
So, be aware of this limitation if you are pushing the boundaries, such as flying FPV and you cannot actually see the drone behind some obstacle (building, tree, etc…) and you want it to RTH or its battery is low and it wants to RTH, it ain’t gonna happen…
