@mountkidd I tested the RTH home location once and determined it to be the location at takeoff time and not first fix. I powered up the bebop in location A and allowed it to get a fix. Then I move it to location B and let it sit a few minutes and see the flight plan icon stabilize. Then I took off and flew away and did rth it came back to location B. Did yours do differently? ..or maybe im confusing my tests. I remember trying ipad location. mountkidd wrote: Tim84 wrote: foundobjectwind wrote: the RTH either rises first to 20m or stays at its current elevation if its higher than 20m Thanks FOW. Do you know what it rises to 20m above? 20m above home location, or 20m above current position? As per (c) this is quite vital to know! I'll update the images later to reflect the drop to 2m incase anyone else views this post as I don't want to mislead anyone. It's good to know in detail how RTH works before I lose my BB or crash it into something terminal...! Altitudes are relative to the home position. Home position can be First Fix, Takeoff Position or Pilot Position. By default in FF3/FFPro, home position is First Fix. So, watch out, as First Fix can have low accuracy...
