The Cessna 150, which I trained for private pilot certification in, did not have bladder-stretching range, either. The FAA had a good idea when they added the LSA category, and so far those planes have proved to be successful in the market. What holds back designers of electric LSA models are weight restrictions, and they must conform to FAA specs in that regard, which limits the size of batteries. New battery technology is being developed to reduce weight and sizes, so when those units materialize, we might see some respectable numbers in speed and range values.
