One of the great features of the DJI Naza-M with GPS is the “Return to home” failsafe. With this feature enabled, its possible to setup a TX so that you flip a switch and your aircraft comes home. In practice this works really well and the RCT800 always lands within ~3m of its takeoff point. It seems to reliably land ~3m North of takeoff. Its also possible to setup the RX (certain receivers) so that the failsafe triggers this function. I’m scared to test it (turn of my transmitter while flying) but the RCT800 has this feature enabled too.
What “Return to home” does:
- Craft stops moving
- Craft climbs to 20m (above most obstacles and trees)
- Craft turns towards “home” and flies there (scared the hell out of me the first time!)
- After a brief pause 20m above “home” the Craft slowly lands and disarms
I took the following pictures while using the “return to home” switch on my TX (obviously no hands on the controls).
About 3m north of takeoff (not sure if I’ve got a config problem)… still very good!
