Excellent point. I sometimes find myself trying to pick the flyspecks
out of pepper, when time would be better spent practicing. As John
Ferrell said elsewhere about his flying skills, my skill level also is
not such as to see any difference in my side mounted Moki and my
inverted Y.S. engines in my rather limited flight regime of
Intermediate. The Moki (1.8) is in a Midwest CAP 232 and I also have a
R.C America CAP with a Moki 2.1 in it. Neither have any bad tendencies
I can attribute to the sideways engine placement.<br>

its cylinder on the right hand side of the plane. With 3.5 degrees of

<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>

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. <br>
