Air holes for barometer (APM2)

Hi there,

 

I'm on my first quad and still have my training wheels on, so looking for some advice.

 

I've just added a plastic container (which seals very well) to the frame to provide some cover to the sensitive parts (APM 2, camera etc) and was wondering how many holes and where they should go to make sure the barometer works efficiently.

 

I'm guessing that it would be better to have them on the top/bottom to limit the effects of wind and the copter moving itself causing differences in pressure? is this the case? and if I have a container that is roughly 10x10x8cm what area of holes should I punch in it?

 

Thanks in advance!

 

Cheers,

Alex.
