Paul, there was a question a few days ago about vertical mounting of
 the rotary, for helicopters.

 Of course all rotors must be able to drain, and a single-rotor
 engine will probably be OK for vertical if the gearing is at the top.
 The Mazda 2-rotor with its "handed" arrangement will allow the upper
 rotor to drain but the lower one ends up clogged. But Larry Childs'
 one looks like it could support vertical operation if gears were all
 facing the same way.

 How has he arranged it?  All facing same direction (identical
 plates), or as two two-rotor sets ( two drainage plates and one
 central plate with gears both sides)

 BTW, there have been other engines with "tunnel" non-split cases -
 here are some https://www.google.com/patents/US2698609

 Thanks Paul Randall

 Facing the gears one way for vertical mount is a good idea. Nothing
 that definitive yet.

 Paul, Drains could be built into the stationary gear flange and
 allow vertical mount with gears from each direction.

Sounds good.

I think I will inherit the damaged TTC turbo charger which
will work for testing on the 4 rotor.
I also have a new avaid dry sump pump we can use for the
prototype 4 rotor.

I'll deliver some day along with the Allison planet.
