I presume Bob Mclean's 160 hrs is for finishing glider wings? Even premoulded
ones take a long time to finish because there is always shrinkage and movement.
Most of the time needed to produce a perfact wing is in profiling the last
.010", in other words the primer and final coat of paint.
The point about premoulded hollow wings is that you can put fuel in them, but
there is a lot of internal work to do before you can close up the wing.
Ask the Glasair boys.
Either way it will take 1500 hrs minimum to finish an airplane like Europa, most
of which comes after the airframe is complete and filled. 2500 for a Glasair.
I've done it both ways.
