Topper Ding-a-Lings anyone?

These are a line of robots that I played with as a kid. I especially remember King Ding who had an elevator between his legs where a smaller "Brain" robot would ride up to the cockpit. I know I know, insert jokes here.
Seriously though, it's a really cool line that was way ahead of its time. The robots are powered by smalled powerpacks which would make the robots glide around a track, even upside down. A number of playsets were also released to compliment the line.
Anybody here remember these?






Below are a few playsets that I managed to find over the years. The Bridge playset is the largest of them all and also my favorite.

Have never seen these before, but love the bright colored chunkiness of it all! Are these guys from the 60s or the 70s? Kinda reminds me of the Billy Blastoff stuff.

Chad, the Dings are from the 70's. Ya know how we all wish we could go back in time and buy our favorite toys for their retail price? Imagine this King Ding for a mere $12.88. My God, it's the stuff dreams are made out of.
