I built this in 1983 or ’84 and was able to make it a fully functioning R/C tank with working suspension and two motors/gearboxes. Once the novelty wore off (and the batteries died) it became a shelf model. It has been sitting on top of my shop T.V. for about 20 years. I dusted it off last week (with a garden hose shower) and this is what was under 1/8 of an inch of dust. It was weathered before, I can’t say if the storage added to the weathering or not. No idea where the antenna is now…
