to build a direct drive fan. I have one that I ground tested for
150 cycles at 6800 rpm with a tired 13B. It would be a snap to do a 100 mph fan.
Mine's design point was for 250 mph with the inherent penalties as low
speed.
I can send you a picture if you're
interested.

OK, hat's off, I'm
listening :-)
I'd love to see pictures
of what you're talking about. My uninformed understanding of "fans"
was that they were good for cruise speed, but not climb thrust. I just
never imagined one running on a 40-100 mph plane, which is why I didn't take
Thomas' post as seriously as maybe I should have. Would it be lighter
than a PSRU and prop? Would it even fit on a SlingShot? I just have
no concept of what you're proposing, but I'm now mighty
interested.
Thanks (to Thomas
too)

parts, and planning cooler
locations)
