Hi all,
I am new to drones and bought mine just recently (spark fly more combo). I did only 29 flights and 2hrs 12 minutes in total.
Today when I was flying and when the battery level dropped I decided to return. At this stage, the drone was not far from me, only 38.2 meters, the battery was at 18%, 2:28 mins remaining, so I started navigating back to me. After 8 seconds I got a message "Tips: Low Power. Aircraft is returning to the Home Point." At this stage, the battery was still at 18% (all this info is from Flight Records in the app). And it was at this point when the aircraft started ascending, and because the aircraft was ascending directly to a tree, I wanted to avoid a collision by putting the throttle down, but nothing happened, the drone was still climbing.
From the moment I decided to return and land, I didn't look at my phone screen because the aircraft was in a line of sight and I was maneuvering to avoid trees and bushes. When the aircraft was not responding to my remote control input, I checked phone screen, where I could see "stop" button (red circle with X on the left of the screen). When I tapped that icon, nothing happened (maybe momentary phone issue?). So I started panicking because I could see my drone climbing into the tree and could do nothing about it. After two or three seconds the drone hit the first branch, and because of the sudden loss of revs it dropped few meters (one or two), then stabilized and then started climbing again, and again hit the branch with leaves and again dropped lower. After that, the drone started responding to my remote control, however, it still wanted to climb and fly towards home point. It was really difficult to catch the drone with one hand while holding the throttle down with the other hand and running behind it. Must've been funny to watch if anyone saw me.
Luckily, no damage to the drone, there are just a few marks on the propellers from chopping the leaves.
My question is:
1. Is there something weird about what happened to me today? Or was the drone just climbing to predefined RTH altitude? Is there option to disable automatic RTH in case of low power?
2. How exactly does the RTH work and why it was triggered automatically?
3. What can I do to cancel it in case my phone stops responding? Just press the button on the remote control? And what would you do if you don't have a remote control, aircrafts goes into RTH automatically and your phone freezes?
Thanks and sorry for such a long text, but this event freaked me out a bit.
