Seems like dji implemented a safety feature that sends the drone back home at a low speed. In reality, if there were obstacles in the way, a low speed would be a smaller impact, but would still be an impact, so there is no real gain achieved by slowing down the RTH route. Here is where I have an idea: have 2 RTH modes: direct and traceback. direct will fly straight line, as it does now; traceback will retrace your path in reverse, maintaining altitude history; All information is available in the logs that are used by tracking. Both could be flown at maximum speed. The selected return speed should be the one that yields the most distance traversed per amphour. The pilot will select traceback if he flew the drone around obstacles or direct if it was an open field.
