bill,
the ighter weight of your engine has little effect on CG--- as long as you
lengthen the arm by extending your engine mount. Staying within the
appropriate CG is important so solve the distance from the datum for the wight
of the engine--
A two pound weight at 100 " has the same effect on the CG as a 200# weight at
1"
Fly light--& balanced
