I was out flying this morning and thought about this post from last night and I decided to try it.
First off, I still offer my advice, if you want to stop your drone, just let go of the sticks. The drone does everything in its power to stop.
I performed some testing, abet not scientific, but involved enough to know that I will never depend on the RTH button to stop in an emergency.
I performed the following test flying at Max Speed Forward, Reverse, Pitch Right, Pitch Left, Yaw Right, Yaw Left, Climbing and Descending… With my
Mini 2 flying at full speed and flying Forward, or Reverse, or Pitching Right, or Pitching Left, at max speed, my
Mini 2 immediately went into "Maximum STOP Mode." Meaning with the
Mini 2 flying full speed Forward, and I released the stick the Mini immediately went into full Reverse to slow down even quicker until it stopped completely. The same with full Reverse and I released the stick the Mini went into Max Forward until it stopped. In addition, the same effect on Pitching Left or Right…
When Climbing, Descending, or Yawing, it seemed to just stop, nothing special about the action (as in no counter action…)
Now for the reason why I will never use the RTH to stop any action other than a RTH…
First off, let me say, this might even be dangerous… The reason being is that it caused the Drone to "Freeze Up" as if it is Paralyzed like it had a "Stroke…"
Next, it is not an Emergency Feature! When I activated the RTH with the stick in a Max position, the Drone did not go into STOP Mode, it merely slowed down and then stopped (drifted to a stop). It acted more like a non-GPS Drone. Additionally, the Paralyses or Freezing Up I mentioned earlier was the Drone becoming unresponsive (just hovering) until I moved the sticks several times, and after several swivels of the sticks, the Drone finally responded again.
So, my final advice is to use the RTH Button to activate a Return to Home and if you want to cancel the RTH, push the button again.
PS: And I just thought of this, as I said the test was not scientific, but I have tested the RTH button and I've tested the RTH Cancel, but I did not test to see if I hit the RTH button to cancel the RTH, would that also cause the Drone to Freeze up until the sticks were wiggled a bit… I'll leave that test to all of you who have inquiring minds…
