Paul,

    Marv isn't catilevering off the front cover,  neither am I and neither
is Jim M.  We all cantilever off the front housing.  The cast iron section
that the front cover bolts to.

    On plugs up..  what have you learned?  What practical data supports your
theory?  There are more flying rotaries with plugs up than not (excluding
Gyros who don't have a space issue).  No one that I know of has suffered a
problem as a direct result of plugs up.  Ed's current problems were probably
there from day one and was a problem when the engine was in the car.  Add to
that, Ed admited to running the engine very warm on more than one occation.
What I learned from Ed is...  put a new or freshly rebuilt motor in your
airplane.  Never trust the auto wrecker.

    I'm not suggesting that plugs is the only way.  But it is a sound,
practical alternative which has REAL flying hours to back it up.

I don't agree Neil. There are enough problems getting the rotary
to work in an airplane without asking for more trouble.

The cooling system and the oil drain back system were designed
for upright operation.

The upright engine also allows a more conventional motor mount
which results in less stress on the housings.
