Lancair lists their various prop options here . Hartzell typically has a 6-8 week lead time. Not sure about MT. The MT's weight is more in line with my old prop (which was 50lbs). But I have heard reports of MT props slinging oil/grease due to seal problems. The Hartzell is tried and true but much heavier (and it only comes in that boring gray color!). Feathering vs. non-feathering - the standard props we use go to flat pitch if we lose oil pressure. But that's only a single type of engine failure. If the engine quits completely for any other reason oil pressure will bleed off. Once that happens moving the prop lever to low pitch won't have any effect. Do I have that right?
