Leester,
I don't think that one at Sam's is the elusive Fox Stunt 60, rather it is a Fox Eagle. the Fox Stunt 60 has been heard in the wild, but I have never really seen one in captivity.
Also I looked at Virginia Hobby Sport Page. That one too is listed as a Fox Stunt Eagle. Is this really the same thing as the lightweight engine that we have been hearing about for the last year or more from Fox??
