I think all civilian Chippies (so these days, that's all of them bar the BBMF) don't have cartridge start. And the ring mod on the pistons largely tames the oil consumption, though you wouldn't think it as you crawl underneath post flight all the way down to the rear of the fuselage wiping the oil off!
That's assuming you aerobat it. But doesn't everyone who is lucky enough to fly one?
