Hi Al,
I think to begin we should examine the following statement;
"Marshall from Skysports sent me a message stating they had
invested a small fortune developing the circuit, and
couldn't divulge any of the details."
That is strange since Jim Weir designed and built one in
Kitplanes (full schematic & parts list with a parts cost of
about $10!) see http://www.rst-engr.com/kitplanes/ ,
June-July-August 2000.
