I would like to fire up my OS 91DF on a test stand. What would be recommended to do this? I am not set up to mount the shroud so using the DF setup won't work. Though I could modify it to do so I guess. A prop at those speeds, not safe I wouldn't think. ?????????
Eagle Flyer,
you CAN run you OS.91 on a test stand with a prop - that is one of the best methods of running it in - use a 11/9 prop and do the rich/lean fuel line pinch when you do it. Just be careful and use a good quality prop and test stand. I have ran Rossi 105 -90-81's OS.91-65/s-K&B 100 - 7.5 -6.5 and too many others to count. Never had a problem doing it.
