Sideways engine?

[John Ferrell]

That makes sense to me. I am really surprised that the question did not get a bigger response though. 
I am way too lazy to conduct any testing on my own. I probably lack the skill necessary to discern the difference any way.

  John, 
  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.

    From Eric's recent post on another topic:Mounts his engine sideways> Uses a  more regular header etc.I have forgotten what the advantages are to inverted engine mounting. Like the matter of retracts which seems to have become a personal choice, I wonder if it really matters to the flying characteristics. An engine on its side is more tolerant of flooding, easier the plumb the exhaust, easier to connect/disconnect the glow plug. I expect that it would spin & snap differently depending on direction, but that seems to be the norm with the engine inverted too.  John Ferrell
