Havnt tried bugs, What you want to start out with is a slowflying trainer that is small enough to fly in a park. Check out the great first planes thread. I think the most popular are the slowstick by gws, the skyscooter pro 2, and the aerobirds.
Out of those three Id pick the slowstick, its stable and easy to see. I dont care for the aerobirds, they are throwaway toys. Just my opinion
