Sideways engine?

[Del K. Rykert]

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.

  Del:
  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,

      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.
