Model rocket manufacturer Estes Industries sold a radio-based
locating device called Transroc that fit inside the main body
of a model rocket or model airplane.
I'm interested in radio-based locating devices, including the TRANSROC and
associated accessories. If you have one of these devices gathering dust in your
attic or basement, send me an e-mail!
More information about the TRANSROC TX-1 transmitter and associated accessories,
along with scanned manuals, is available at
