I am quit sure it is not housing or light problem, because I try to cover it
and result are the same.
Also you can see the Baro raw output even with one or two fault in 10 mins,
it should not cause estimator.Z has that big amount of fault. so I say the
BARO RAW is acceptable. but estimator.Z has problem.

the Chinese AP has many different version, some are using BMP85, but the one
I have is using MS5611,
But I guess the Chinese one MS5611 is not really, maybe a copy, otherwise
the precision can not be different. Am I right ? who know. But I think it
works :D just quality different :D it is enough to fly with my fix-wing. Now
it is hard to buy the newest Lisa/MX board, not too much provider, and all
out of stock. So have to fly with low quality one.

If you want to buy it, try to find it in Taobao, or write me a message I can
help you.
