RE: OS 91 VRDF experts wanted
Mike Connor and I had discussed the possibility of doing up a modified SD with one of these engines, the one that goes with the pipe pictured as a matter of fact. I had thought about going the DF route but a propped version makes a lot more sense because the fan isn't all that efficient. I was thinking that a SD airframe scaled up to a 36-38 inch span should be about right proportionally.
