A 2000' runway sounds to be only about the right size for ultralites. One of the local fields here is own by a retired gentleman. He owns and operated ultra lites off of the field as well. We have special rules for pilots that govern their location on the field to make sure they are within view from the air. The ultra lite pilots make a circle of the field to warn us of a landing and then we get our planes down for them to land.
There are a lot of single engine full scale aiplanes that are perfectly comfortable on a 2000 ft runway, and even some multi-engines.
A DeHaviland DHC-6, a twin turbo-prop needs less than 200 feet (repeat 200 feet) to takeoff or land when if full STOL mode and at gross weight of 12,500 pounds. I have almost 2000 hours flying this model, I know.
