AXIFLO RK-049 Ducted Fan?
I just picked up one of these at a swap meet. It was made by Midwest and designed by Kress. It is in kit form, and will require quite a bit of building and head scratching before it is complete. The plans say it will produce 16.2oz of thrust @ 20k.
Anyone know anything about this DF? plans are dated 1978. I can post pics if needed.
