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.
