Well, I had the same problem. Lot's of stuff you could do, but my favorite solution to eliminate the prop hits was to eliminate the props. I changed both engines to turbine. Makes everything rather fictional... and sure, the plane is out of site before you can blink, but it's a lot of fun in the "Pilot behind aircraft" view. The only other problem is that the fuel only lasts about 1 minute, but once the fuel runs out, you can land it.
