Spose its too common sense for most but 'if its not broken dont fix it" thinking applies in a lot of cases! flywheels are needed (as are harmonic balancers). The suggestion from Phil re belted reduction drives is partly correct as to allowing engines to produce the designed rpm/power, but belted reductions impose side thrust on the rear main bearing. Neil Hintz (www.autoflight.co.nz) produces a PSRU that uses a flexible coupling to isolate the engine fom the reduction gears which seems to be a sound engineering approach. (the PSRU would provide some measure of flywheel inertia effect I would think). Just more fuel for the fire of debate!
