Uhh, last I knew model rockets basically went more-or-less straight up,
and then down on a 'chute subject to the whims of the local winds.

I don't see how one is going to get a usable stereo pair from this
mostly-vertical (or in the case of the descent, combined horizontal
and vertical) motion.  What you really need is two rockets, separated
by the desired stereo base, that take syncronized pictures (perhaps
by radio signal), or else take your two shots on two separate firings
with the launch position moved by the amount of your desired stereo
base, and the picture triggered at the same altitude, perhaps by a
timer.

Sounds tricky, but if you pull it off you will have some very unique
stereos!
