  Marv and Rick,
  
  That was a great worksheet, but after looking at it, I didn't find what I 
was
looking for. How can I work numbers on a engine with a different weight? I
have a short engine mount.

[Without actually weighing the airplane it's difficult to estimate what the 
changes will be...  your moments will also be slightly different with the 
change in arm for short mount.  I think you will need to plug in your real 
measurements and weights in order to do a direct comparison.  W&B in a LNC2 
isn't exactly the kind of thing you want to fudge.   I know of at least one 
LNC2 with a short mount, O320 & fixed pitch prop, and on that airplane, even 
with a 12lb platter at the base of the spinner there isn't enough weight 
forward to allow the carrying of a passenger without going aft CG.  Definitely 
not good.   <Marv>    ]
