S800 - WKM - Z15 descends in GPS mode

[r44heli]

Hi All,

Has anyone with an S800 and Zenmuse had it start descending from a hands off stable hover
with green flashes from the LED? It then recovers after around 20 feet and LED goes back to
blue?? We have had this on most flights in the last couple of weeks and are a bit stumped.
Apart from this it is supremely good.

Thanks

Roger

If you look at the manual it states it could be IMU loss of signal. I would be concerned as this is not normal behavior especially with a ZEN and camera onboard.

Hi - Thanks for your reply,

We moved the ImmersionRC downlink TX to the front of the machine, further away from the IMU, changed the vertical gains to 80/80
then flew again today and it was perfect.
