I really love the Ultimate 10-300 from any manufacturer, but the Carl Goldberg is the first Ultimate that I saw fly (back in the early 90's). I have another ultimate that fly's great! It is an Ohio R/C Ultimate 10-300 with a 63'' wing flying on a 45cc CRRC engine.

The sound of gassers are so tempting.
