Over the years many people around the world have asked “Do you have an engine that will run on automobile fuel?” Many areas of the world do not have access to 100LL aviation fuel. With the thought of the Environmental Protection Agency outlawing leaded aviation fuel, we decided to bring back our V-8 powerplant as an optional engine in the Hummingbird. We decided to use the General Motors LS7. This engine is specially designed and built for the Hummingbird. It is not a stock LS7 engine. This engine is configured with the best components available on the market including forged crankshaft, connecting rods and pistons. A special designed camshaft optimizes torque and horsepower at the continuous r.p.m. of 3250. A dyno chart is provided below. The blue line is torque and the red line is horsepower. A newly designed cast aluminum oil pan and specially designed cylinder heads have been created specifically for the Hummingbird helicopter. The exhaust system required extensive test cell time in order to optimize the power curve. The computer system is programmed for the Hummingbird application with redundant communication with critical input sensors. The throttle is fly-by-wire and is fully governed when set. Wide band O2 sensors provide the capability to use 87 octane auto gas up to 100LL aviation fuel. The oil system is a dry sump design with an optional oil cooler for extreme operating conditions. This engine was configured for the Hummingbird and will make 325 h.p. at 3200 r.p.m. It is derated to 280 h.p. and will produce 280 h.p. up to 12,000 feet. This is the only helicopter available that provides sea level performance to 12,000 feet with a piston engine using auto gas. Engine installation is simple and easy to maintain. It starts like your car, runs smooth, and is quiet. Thanks to everyone that made this happen.
