Here's a brain teaser for you:
Facts:
- Home point was set
- Flew to about 350m away
- At 350m away, I tried to land (controlled area with only family in the area)
- landing site is about (-)75ft AGL from home point (site is 75ft below home point elevation)
- lost RC and video signals just inches from the ground (I know why - so don't worry about why I lost signal for something that should get 3mi range for this topic)
- it hovered for about 30 secs (after signal was lost)
- then it landed, props stopped but battery on the P3P was still on (94% battery life when landing)
- record shows that my elevation at landing was -24m so it did record negative elevation.
Variable:
- after FW update - fail safe altitude setting was set to 30m (I had it at 120m before - Note: always check after updates)
- Fail safe was set to "return to home"
- I've only flown from home and at same elevation, just a matter of backyard/front yard (regarding home point sets and compass calibration)
Question:
Why did it not initiate fail safe RTH when signal was lost for 30secs?
