engine. It has an empty weight of 600 lbs, fuel capacity of 22 gal, and fuel
burn of 8 gph at 100 knot (115 mph) cruise speed. (Max Range, 2.25hrs/.5hr
reserve 258 miles) Airspeed Limits VNE (Never Exceed Speed) at sea
level is 115 knots (132 mph) CAS. For reduction of VNE with altitude,
temperature and N1, see FAA Approved Rotorcraft Flight Manual. Autorotation VNE
at sea level is 115 knots (132 mph) CAS. Built
under Kit and Amateur Built Rules.
