Subject: Pietenpol-List: 4" don't mean squat On the other hand, there was discussion in the BAPNews once on how acenter section cut out had a drastic effect on performance of the Piet.Could a 4" clip have the same effect? I don"t recall, but I wouldimagine it was a Ford Piet. Probably a combination of the cut out andthe radiator location, the radiator blocking air flow over the centersection. I'm wanting to use a cut out, so am thinking about anunderslung rad. Leon S.________________________________________________________________________________

The cutout problem was not just loss of lift area but induced drag. Noinduced drag if you just shorten wings. The test aircraft, if I remembercorrectly was also on the heavy side.
