Hi, I have one of these old DF engines and I was wondering if anyone had any experience with them.
I am not in a hurry to find a home for it and I wonder what kind of performance you can get out of one with a prop up front?

Is it comparable to an OS .91 VX-DF?

Since parts are no longer available, should I sell this and get an OS? If yes, how much can this go for?

In a really clean airframe with a CF 9x10 or 8.5x11 you could easily top 200mph. In a sport speed type of design 175-190. Note that I don't mean an H9 Jackal or a Sundowner or that sort of thing - those are relatively chunky airframes.

Dude, I would keep it and build something for it
