IMHO, the weight limits on Light Sport are the totally unreasonable
determination of a bunch of desk jockeys. At the very least, they should
have accomodated the weights of two seat basic trainers commonly made and
used in the United States. The cost to build and maintain an aircraft of
750KG gross weigth would not be substantially more than for a 600KG
aircraft--and would very likely be less. In attition, it would have put
more companies and craftsmen back to work here in the USA.


Someone else said the utterly obvious ten years ago-if a light
airplane is arbitrarily defined at 12,500 lbs, an ultralight ought to
be 1250 lbs.
