Sideways engine?

[Gray E Fowler]

Wayne....I was outside.....68F, no wind, bright sun........I was nice 
enough not to inform you or Lance knowing that you lacked the discipline 
to stay at work.........

AHHH yes spring.   Got 8 flights in last weekend on two planes with 
inverted engines.  Should be out there today 65 degrees and nary any wind. 
 But alas....  I have to work till dark.

Amen to both counts!  I'm ready for Spring, also, and it really isn't cold 
here.  Now, if I was just back in Las Vegas............Bill

Hi Bill.
 
    I would also like to give credit to those that are capable and have 
the knowledge and tenacity to research and find answers that lead to 
better flying models. What we learn in pattern I have seen trickle down to 
the sport flyers also. I sure give credit to those that do think and come 
up with solid answers.

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.

Some good points.. Not sure I could ever justify the time and expense 
getting the answer. Time on the sticks through focused practice is still 
where my time earns biggest result. < VBG >.

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.
 
Now al all of the above poses a new question, if you care, of how much of 
a problem we are creating by offsetting and inverted engine 3/4" at the 
back of the engine--- Hmmmm.
 
Also the mass of the mass of the engine has always helped in level flight, 
when side mounted as it weight is opposite to the counter-rotation caused 
by the prop.
 
It's January, it's cold - even snow, and we are back!
 
Regards,
 
Eric.
 
P.S. The wide body cheek type cowls allow an extremely neat installation. 
The Rhapsody had a chin cowl with nothing in it. It was just for access.
