RE: Using a DF OS .91 as a prop plane
Yes and does it work! I finally put my new OS vrdf .91 on the front of my old EZ Dago Red (55") with the belly scoop and stock cowl changed to a Stiletto Configuration. With 15% and an 11-8 apc I did have my hands full. At a slightly rich setting using a 13.5 cc pipe, it was moving faster than with my .65 vrdf and stayed even with the .77 which has been clocked at 180 mph. Static it was turning 22k plus and VERY LOUD. I will lean it out this weekend. This is one fast bird which is rock stable. Even the tendency for a 'fall-out' in a pylon turn went away with the .91........ any ideas???
