Don and & Bob,

What are your numbers on takeoff, climb, and cruise?  From what I have read sounds like a shorter takeoff run and better climb and a negative in cruise.  Is that true?

In cruise do you have numbers for 18-20K?

Thanks,

Jim

I almost hate to admit I do not keep that close an eye on numbers. I only speak from how it feels and a general sense otherwise. That being said, I noticed it jumps off the ground quicker and seems to climb better. And I can not discern any difference in cruise.

I’ve only ridden around in a J with an MT prop and it is so much quieter I’d consider it maybe an even trade if you lose a knot or two in cruise.

We've had the MT 3-blade on our E model for a little over a year, and really like it.  All of our findings are the same as the others with the exception of the 14 knot loss that someone on this thread had.  We see no change whatsoever in cruise from the Top Prop we had prior.

The one strange thing to get used to is  the much lower flywheel effect of this prop.  When the mixture is pulled, there is very little rotation after the fact.   I have been wondering what would happen were I to forget the electric fuel pump, and have an engine-driven pump failure at exactly the wrong time after takeoff.  Would the engine spool down before I could reach over and flip the switch?  So...I've made it a practice to always use that electric pump.

I’ve run a tank dry on my Comanche with an MT prop, it does not windmill very well.
