Aloha Icarus,
This is not one question! You have just destroyed the party! You also forgot to mention that if you touch the stick while it ascends it will stop ascending after 20 meters (65 feet) and follow through to RTH.
Now chasing you down. If the RTH changes, the logic says that the RTH changes to. This means if you change the altitude of the first Home Point to the altitude variation of the second Home Point, the altitude changes. RTH is a concept, a united concept consistent within itself. (If this is not the case, DJI has a very serious problem.)
The default Home Point is set by the Remote Controller. So your position in the "tree house" (with the controller) is the home point, but you have the option of setting your home point to the location of the Phantom. So, either one, your choice.
Now your Critical Battery Level (10%) question is one I have personally experienced. Dude, if your drone is out of juice, it needs to seriously land, like worse than needing to take a piss! It can die if you keep it airborne. But within the limits of battery juice and geographical space, with the thrust stick at max upward position, you can determine how your drone dies or maybe save it.
Your 30% battery level question is basic to all Phantoms. No difference. The 30% battery level is a warning. Above and below 30% is a power programming issue and you need to pay attention to it. If your phantom (3 or 4) is close to too far away from the declared Home Point, RTH will be initiated. (I have had this occur at 34% during a "Follow Me" expedition.) It is indeed a function of the firmware and I am confidant that it includes the 10% critical battery buffer.
The P4 Sport mode has the same effect on RTH that ATTi has. If you are pushing it so far that you need to speed home, you can expect a crash as a reasonable outcome for the technology. You really need to give yourself a time cushion so you can land softly.
Please Geebax and labroides, if you can offer any corrections or illumination of these principles, please do. At this point for me it seems pretty straight-forward.
Aloha and Drone On! |
