Hi all
I'm still tuning my large X8 platform and keep encountering a rather alarming situation where the HUD on the GCS doesn't match the vehicle's attitude when hovering!
So the HUD might be showing a forward pitch / pitch down position, so the system thinks 'I need to give a pitch back command to cancel this forward drift' ... and in the mean time I'm having to fight it by holding forward stick just to keep it level! When I land the HUD then settles itself.
It's quite noticeable when it first 'forgets' what is level as it will suddenly start drifting off quite quickly in one direction.
What's going on here? Is the attitude estimation getting upset by too much vibration? When the platform is on level ground (and actually at any time when it's not flying) the HUD correctly reports the attitude of the vehicle.
Many thanks for any suggestions
David
