<DIV><SPAN class=113553418-14012004><FONT face=Arial color=#0000ff size=2>You
should also consider that the engine has its cylinder on the right hand side
of the plane. With 3.5 degrees of side thrust the bulk of the crankshaft (The
heaviest part) is displaced to the left of center if the spinner is centered.
Balance an engine sometime on its side and you will see that the CG of the
engine is not on its thrust line.</FONT></SPAN></DIV>

al all of the above poses a new question, if you care, of how much of a

the engine--- Hmmmm.</FONT></SPAN></DIV>

the mass of the mass of the engine has always helped in level flight,

<DIV><FONT face=Arial size=2>Well I will bite to only suggest that the mean
center line of the CG is what would have the most significant reference for
snaps and engine mass if located same distance from CG and same off set of
midline then how can orientation of a reciprocating moving mass have any
differing effect on the stalled snap of the aircraft as we can stop the snap
in any attitude we choose to with the same results only difference I've ever
noticed is timing. It may be so subtle that it is hard to detect but I
do fly my aircraft very neutral and suspect it would be most noticeable in
that trim state. </FONT></DIV>

<DIV><BR></DIV>John, <BR>I'm not sure if I'm right on this, but I think
that I would like to have all that Mass(bulk & weight of the engine
head) located on the centerline of the aircraft.I think that all that
off-center mass could produce some unexpected and unwanted effects during
snap type maneuvers(and probably others) where radical changes in aircraft
speed differentials might magnify the off-center forces in a detrimental
way causing exagerated pitch and roll responces making control during
certain maneuvers difficult to compensate for. I don't have any empirical
data to back any of this up, but it just doesn't feel right to me.
