1. Electrically controlled props
2. MT Three Blade MTV-12-B/183-59b, on YIO 390 down to 80 Kts
3. IO-360A1B6 with non-aerobatic Hartzell prop and MT Governor down to 80 Kts
4. 0 320 with a Hartzell prop with the MT gov
Looks like the common thread on a non-aero CS hydraulic prop is an MT governor. My understanding is that the governor is both a regulator and an oil pressure booster. So perhaps the MT governor has a higher oil pressure output at lower RPMs than other governors.
Would be nice to have a prop person like the folks at Catto weigh in.
Original question:
Hello All,
I would like to try to harvest some anecdotal information and repost a summary of which CS props and engine combinations yield control in engine out scenarios.
If you have done true no engine power testing (Not idle, but truly no power) and found that you can still control your prop to the course position please post your prop/governor/engine and lowest observed controllable airspeed in Knots.
Ideally a builder could consider this aspect of extended glide as worth one prop combo or another.
