I know this will probably sound dumb but I have an os.91DF that has never been run that I bought for a ducted fan that never got built. It may in a few years so I don't want to just sell it. Is there a use for these at all in a propellor plane or can they only be used in a ducted fan?

If they can be used in a prop plane, can anyone suggest what size prop to run and what kind of airframe it will work well in? What kind of properties do these produce when run at propellor rpms? Do they have much torque? Also, what kind of muffler other than a tuned pipe can be attached to the rear exhaust fitting with the big o-ring and how do you attach it?

thanks

Use a 13-6 prop and put it in the planes listed for 60-90 size engines

I had a brain fart and after it cleared up , I remembered this. There is a website that sells the Old Bridi kits. One of those planes is set up to hold a rear exhaust ducted fan. Would be perfect but cant remember the site.
