Subject: [FlyRotary] re-drive question for Tracy

Tracy,

   Ian brough up a point that could also apply to the re-drive.  Since the planet ass'y was originally designed for lubrication with ATF, is there any particular reason why it couldn't be run as a closed system with a "scavage" pump circulating ATF, instead of using engine oil?

   Dunno if there's any advantage to the ATF, for that matter, but I thought I'd ask.

Dale (to whom the thought just occurred that this may have already been discussed - some years ago - and could be in the archives.)
