I doubt it Noel. The heads do ride on air but for sterility reasons in a
sealed air capsule which was sealed in a clean room. The most likely
problem is that the air tight capsule which is sealed with a sticky label
will be compromised. This will ultimately lead to contamination and disk
failure. The smallest mite of dust etc will cause a head crash.

Nope. That is a common misunderstanding. Most hard drive units are not
sealed and are vented via a very fine filter. The reduction in air
density and head flight height is the reason those hard drives have an
altitude limit. Some people with hard disk drive based iPods trying to
use them in gliders found out the hard way. While you might get lucky
for a long time I would worry about the vendor's max altitude specs.
Some specialist drives are pressure sealed, not likely the ones you'll
find in consumer equipment.

Not a problem in the cloudy little UK, where we dream of getting above
4000ft AMSL due to our generally low cloudbases!

Thanks for pointing this issue out though. So I guess it's Mini DV, Mini
DVD or SD card camcorders. Any known problems with these?

One other issue we have found with exterior mounted cameras at high
altitudes, or on cold days, is that the cold affects the battery
performance. Make sure that the batteries are fully charged up before you
start, and don't expect them to last for too long.

Anybody have a recommendation for a small thin digital camera with
decent quality that might be suitable for taping to a winglet for
inflight down-the-wing shots, with a connection for an rf remote? Have
not been able to find a small camera with remote option. Thanks...


It might be worth looking at the FlyCamOne, which was developed to take
pictures from RC models. It is small, light (37g), records to an SD card
and can be remotely tripped via an el-Cheapo RC set or configured to take
a shot every few seconds. The resolution looks to be adequate and the
cost is pretty reasonable.

Sorry - that should have been:

or

which shows prices and another video. BTW, anybody fancy a small, light
backup logger?
