For me it changes with every site to be about 30 ft above the height of the tallest tree / ground hazard. If you are not sure what that is you can set your gimbal straight, fly to the top of the tallest thing and your current altitude will tell you.
Thanks all
Can you do this while in flight or do you have to make a note of the height and set it when landed?
Obstacle Avoidance is active during RTH. So even if you estimate wrong and your drone has OA, there's a chance it will successfully avoid the tree/building/hillside and make it back safely.
4. The first time you run low on power (approaching 18%) while in flight you'll get a warning about auto-RTH in 10 seconds. Be prepared to cancel that fast with C1 if that RTH would compromise the crafts wellbeing.
5. If you do cancel a low power RTH really do get home fast, or you may find it landing itself before you are ready and wherever it is now !
Both RTH height and the maximum height can be changed whilst the drone is in flight, BUT the RTH height can not be changed whilst the drone is executing an RTH.Can you do this while in flight or do you have to make a note of the height and set it when landed?
That would only be around 18% if the drone is quite close to you.4. The first time you run low on power (approaching 18%) while in flight you'll get a warning about auto-RTH in 10 seconds.
Yes, very important to check RTH before you fly every time.
