Microlight:-
Best Features: cheap to buy, cheap to run, cheap to maintain, small, compact, portable, lots of stuff added in cockpit to play with/look at/adjust when flying gets a bit boring, gear "down and bolted" all the time, takes off in nothing, lands in three quarter of nothing.
Worst Features: Weather-limited, 2-stroke engine (but it has been a gem so far...), feet get cold because of airflow through nosewheel cutout in pod.
