How bad would leading edge radiators foul the rear prop on a push/pull tandem arrangement? Would downwash over the wing keep the hot, low-density air out of the prop? Or would the rear prop draw this messy air back up through the arc of the propellor? If the messy air does go through the prop what kind of undesirable effects would be expected?

The attached drawing is meant to illustrate the question but not, of course, the actual airflow. For pushers and tandems the practice seems to have been to exhaust the hot air at the base of the prop. I could do this on this design but there are packaging problems that would be improved if leading edge radiators turned out to be workable. Ideas?

Thanks,
Rob
