No one mentioned the Boomerang Intro (Baby Boomerang). All the same qualities as the XL, but in a smaller package (76" span) and at a lesser price. Flies great on a JetCat P-60 or P-70 or anything else from 12 to 18 lb. thrust. And it's perfectly at home on grass strips. Mine gets off great in about 150 ft. with a P-70.
Go here to see both the XL and the Intro:
