Designed by Mr. Scramm, is one of the most popular kit-helicopters ever offered. Made of steel-tube and aluminum with fiberglass outer covering, builders assemble it at their own pace using sub-kit method of assembly. Powered by a converted outboard-motor engine. Has semi-rigid teetering main rotor and belt-driven tail rotor. Is 2-place version of single-seat Javelin. Scramm has since designed improved Scorpion Too, called the Exec, with more streamlining and better performance.
