Postby zhlearnaq » Sat Oct 17, 2015 3:41 am

hello.
whether the calibration should be done again in a new place and why, dose anyone know that? Please. Recently, I took my aircraft to a new place(I know the Acc value have changed at that place) , it dosen't work well, when back, it works well again, the mag Declination and other value have be changed to local value, what may happened?

I have found the problem. The press height is too large. Does this mean that the aq can only work in specific height? Why no one reply to me? Anybody have sugguestions? Thanks very much.

The calibration of the FC only needs to be done once.

Inclination and declination should be changed to the values that are correct for your location.

hello Larry
Thanks very much for your reply, I have changed the mag value and I have found the reason that the PRESSURE value is too small, but i don't know why this happen, dose this mean that aq can only work in Low altitude region?

The pressure sensor has a very large range of pressure sensing so I would think that should not be a problem. I have not heard of any problems with high altitude flying.

I have done many flights with take-off's over 2500m with no problem. Wish i could offer some advise, it just has never been a problem.
