I'm not exactly sure of the year, but Great Planes/Tower Hobbies bought Top Flite after Sid Axelrod passed away. All they wanted was the rights to MonoKote, Top Flite props, (which they planned to redesign) and the series of classic R/C kits which they redesigned . Everything else was destroyed and pushed into a dumpster. All the tooling for all Top Flite kits, existing stock, everything. That is the only way to completely dissolve a company because the tooling is part of that company. That is how Brodak was able to produce all the George Aldrich designed kits by their original names. When the tooling and the original company was terminated, the rights reverted back to George. I have to think this was sometime on the early to mid 1980, maybe later. I may have some details wrong, but that is the way I remember it being explained to me by someone who said they were there and witnessed it.
Type at you later,
