Bill -
Yes it is interesting to see how far the original concept has morphed into what we have today.
It was clearly inteded to be a much heavier class of model when you look at the use of 1/32 prop shafts and plastic props. The use of condenser paper was probably not even a consideration since tissue paper was what was assumed.
My feeling is that it is the minimum weight that is at the heart of many of the problems expressed in these discussions. If the minimum weight is significantly raised then the use of condenser paper or film of any sort becomes almost moot.
If Aki's recollection as to the origins of the 1.2 gram limit is correct (see below)then it was clearly set to arrest the efforts of the expert builder/fliers but not enough consideration was given to the original intent of the class.
