THE COMMUTER-II 2-SEAT HELICOPTER
Construction Manual

The two-seat Commuter helicopter had its origins as a single-seat design in the 1950s known as the Helicom. In the 1970s, the creator of that design, Harold "Pop" Emigh, went on to develop the popular 2-seaters—the Commuter-IIA (photo on right) and -IIB (photo above). To this day these helicopters, with their solid engineering, shaft-driven tail rotor and use of superb Lycoming aircraft engines, are considered among the finest 2-seat Experimental helicopters available.
 

Vortech offers the large, thick manual containing the building plans for the classic Commuter-II. The airframe, control system, main- and tail-drive system, engine mounting, cabin construction, etc. are all detailed. Bear in mind that the control head was sold as an assembled, tested component and the drawings for this unit are somewhat general.
