I have often contemplated the wisdom of this configuration.  I fly Russian warbird aircraft with M14P radials on them as well, and the failure mode is high pitch....seems to make a LOT more sense to me.  Can someone enlighten me on why (from a philosophical standpoint) the engines that spin the other way (i.e. American) throw then prop to high drag upon pressure loss?

Thanks in advance!
