Kip, you got me thinking (dillicult) about my first intro to HC. It was when I was still at school about 1967/68! Some guy had advertised a meeting and brought one along to the Kingsway Hotel in Manchester, I think he was trying to drum up some sponsorship! The HC, from memory, was similar to a Hoverhawk, would this be right for the year? (One lift and two thust "stuck" on the side)
