[QUOTE="Mikel Manitius, post: 10266, member: 1775"] I haven't [I][U]had[/U][/I] to use it yet, but I have tested it many times to see how it behaves. The one thing that I saw in my tests that worries me the most is that with the sun at a low angle the shadows seem to trigger the object avoidance sensor continually. While testing RTH once the Spark was returning back at 30m and then suddenly stopped and got stuck due to the shadows and tree line much lower on the ground (there were no objects within 50m of it). It kept trying to ascend and avoid. I finally got fed up, turned off object avoidance and just brought it down manually. Not a big deal when you can see it but would really suck if it's somewhere where you cannot see it. I also get false object avoidance halts flying manually with it turned on during such contrasty and shadowy conditions. From this experience and other's posts I think it best to simply turn off object avoidance during phases when RTH may be used or triggered. Note that even with RTH off you still get the annoying beeping and a proximity notification on the screen. Once you get comfortable reading that and flying FPV you can just take that into consideration but not be automatically limited by it. So for this reason I mostly fly with object avoidance turned off now. The other two things I take into consideration: - ensure that I never set a home point (or have one set) under a tree or within about 5m of a tree. I don't want the drone descending down into a tree on RTH. - ensure that if flying under trees I never push the battery level low enough that RTH will get triggered automatically, I don't want it to suddenly ascend up into the trees. There are other factors that can also trigger RTH (like a radio disconnect) but I have little control over that. [/QUOTE]
