I'm still all over the map regarding an engine choice. I have been intrigued watchin "Cub Crafters" of Yakima Washington develop a really cool LSA cub model. They are now using an ECI engine (Lycoming derivative) to get 180HP for takeoff and 80HP continuous up to 12,000 feet. If the CH750 can handle the weight (245 dry), that seems like a great option for those of us out in the western mountain states where much of our flying will be back country stuff above 5000 MSL.
Does anyone know anything about this engine? Following is an excerpt from the their website...
...CubCrafters worked closely with ECi, of San Antonio, Texas, on the CC340 engine, which is fully certified to ASTM standards for Light Sport Aircraft...the CC340 is a thoroughly modern version of the venerable Lycoming designs...Therefore, any mechanic trained in the repair and maintenance of Lycoming is equally qualified to work on the CC340. Modern updates include dual electronic ignitions (no heavy magnetos) and lightweight accessory
components. In addition, an innovative cooling plenum more efficiently directs airflow to the cylinders and oil cooler. CubCrafters created a new, less restrictive 4-into-1 exhaust design that weighs just 6.2 pounds (half that of comparable systems). The alternator mount was modified to fit closer to the crankshaft, making the belt shorter and lighter.
The result is an engine that weighs less than 250 pounds, and is rated at 180 horsepower for takeoff and climb, and 80 horsepower for continuous power settings. At cruise power, fuel consumption is as low as five gallons per hour. Used as specified, the engine has a 2,400-hour TBO.
Just to throw another thought into the arena, I just watched a video of Rotec Engineering running a Jabiru 3300 with WATER COOLED HEADS! Not only did this keep CHT's down it also kept EGT & Oil Temps down, and for those of us who live in cold climates provides a perect cabin heater arrangement. No probability of shock cooling during a rapid descent either.
Just something to consider.
