MT prop
      #11646 - 01/11/10 01:44 PM

Anyone considering running an MT prop on their IO-550? I just pulled an 88" Mac 401, and replaced it with a 3 blade MT. Lost 30# off the nose which it needed. Wow, is all I can say. This thing climbs like crazy and pulls like a beast. Don't have actual numbers, but if seems a bit faster on the top end as well. Can't wait to test it out at Johnson Creek this summer. Thanks John @ MT!

My skywagon is a couple of days from being done. It is getting Ti gear, Reman 550 & the MT prop. I also am using the BC alternater 5lbs and the skytech starter. The 550 is replacing the IO-470 so I am prepared to be amazed!

Do you want to sell you old 401? I would like an MT, but the 401 is a bit closer to my budget.

We also have the MT prop and like it a lot. Where did you get your Ti Gear legs from?

MT, I just bought a 185 and installed it on 2790 amphibs. I have a 3 blade Mc. 403 80" and would like more pull for take off 0-55 kts. I've been dreaming about the Mc 401 88" and with what I hear it's great but then you jump out and say the MT is amazing. Hmmmmmmmm. So I've been researching the MT and some are saying that the 2 blade is even better than the 3 blade. Hmmmmmmm again. Weight is critical with our small floats so at this time I am getting excited about the 2 blade MT.
I haven't got costs yet and of course there should be a substantial savings 3 blade versus 2 blade. Maybe you have had time to really test the MT prop, if so please send along your advice, would be appreciated. Anyone else out there that can help would be appreciated. Reason I need to get airborne quickly is because my camp is on a small lake, like in VERY.

Here's my experience.
My 520 came with the factory 80" 3-blade 403 Mac, the one with the "pencil thin" blades. I liked it, it was fast, smooth and quiet. Put about 1000 hours on it. The newer wide chord props started showing up and getting strong reviews. I went with the 80" Harzell Top Prop in anticipation of a future 550 upgrade. I like the shorter blades, less erosion from float operations, and less chance of picking up nicks on wheels is my theory.
The Hartzell does pull harder, though it was not an "omigod" moment. It lowered my cruise speed by almost 5mph. The biggest difference is when pulling back on the power, it is like throwing out an anchor compared to the narrow chord prop. It is not quite as smooth as the narrow chord, my thought being that I feel power pulses from the big fat blades taking bites.
I converted to the 550 about 200 hours ago, and THAT was an omigod moment. Kept the prop and it works great.

I notice a lot of the McKinley mountain flyers use the Hartzel instead of the Mac, for whatever thats worth; they operate at high altitude and on skis.

Any thoughts about the flywheel effect of a metal prop vs the MT? Flyweels can do good things to smooth out big displacement motors......

The quotes I have received are about $14k+ for the 3 blade MT with spinner, and about $10k for the 86" Mac 401 with spinner.
