OK, I guess I was not clear with my question. About half gave answers I wanted, many started off on laws and regulations.
First, I should have said in the USA. Typhoon H's sold here have a ceiling of 400' in the firmware. All I wanted was to check the accuracy of the Altimeter (barometer). In other words, if you live here, buy a Typhoon H and do not alter it or change the firmware limit, how high does it say it goes?
I know even if it says 400' it may not be. I flew 2 batteries just now in the twilight, and this screen shot was about the same for both. Using Brer Rabbit it shot to 410' but immediately dropped lower. Just having fun, wasting time.
