RE: Do you remember...
How about Turbomin T-60 , T-100 Ray and Alberts " RAM's" first push. Any snow melters still around ??
I built 2 Thomas Kamps motors before the design really took off, The first to use a centrifugal compressor. never got one to run right. But worked well as flame throwers. SCARRY stuff back then.
Some may find it interesting the FD3-64 and early 67 used a plywood built Axil compressor wheel. They did work
