Look at the big rigs on the road, a very large number of them are 2-stroke engines pulling very heavy loads for hundreds of thousands of miles. Yeah, 2-stroke diesels. Valves, not ported cylinder walls. Pressure lubrication, not diluted oil/fuel mist. 2-stroke gassers with big cylinders seize a lot, they just do. Except the Rotax in a CH-7, don't know why that worked out so well, when a Mini-500 with the same engine is crap. Almost all the CH-7 helicopters were built and test flown by the factory, not the customers. There are less than 100 CH-7's while there are over 500 Mini-500. Dennis Fetters |
