I've seen both turboshafts and turboprops. I believe the turboprop was a
single spool, too. Shaft connected straight to a gearbox. The turboshaft was
definately a 2 spool engine with a free turbine going to the gearbox.

I've had this urge to build an electric B-58 for a while. Would cure a bunch
of my urges, actually. Delta wing, multiengine, and ducted fans. I think I
can get away with making the entire airframe out of 3 pieces of glass (well,
carbon and kevlar anyway) with 2 spars in the wing and another up the fin
just to give something to hinge the rudder to. Just need to find someone to
carve me a plug since I suck at that part :)
