Yesterday on a lark I picked up a Max Trax to play around with the
altimeter it has. After a cursatory looking over it seems not a
barometric type, so I guess it's a type like a bottom of the line G-Wiz,
of which I know nothing of note about. Amongst other things I'm out to
see if I can fly the thing higher than it wants to read. Does the
altimeter have a practical limit? If so, what? Not surprising there was
flat zero useful information packed in the instructions.
