What prop?

[67M20F]

Ok had a prop strike, one  shop says put the strait blade hartzell back on and one says go with the machully scimitar prop, one says go with the MT composite scimitar.

Don't want to put out a bunch more money on this, and it would have to be three blades, I use the airplane in very high DA, 11K isn't rare.

So what would you put on if it were you.

Oh yeah if it wasn't bad enough, partner is thinking of selling, and I can't buy him out!!(don't have enough income)

 

Soory about the spelling, but in a hurry to look up.

I installed my MT composite last month and wouldn't ever go back. It is lighter than a 2-blade, runs so smoothly you almost don't know it is there, and I get better climb. I live at 7100 MSL, and it works great at that altitude and higher.

[67M20F]

How much did it cost you?

[mjc]

I don't think I'd want to vote on the poll without knowing what the cost is for each option.

[67M20F]

Assume it would cost around 2.5AMU  more to go with the MT.

Would it be worth it?

[piperpainter]

From what others have said on the forum about the MT prop.....2.5 AMU's is worth it! If I had a choice id go with the MT!

[Immelman]

My condolences.

A fellow with a very nice C a few tie downs from me upgraded to the Hartzell blended airfoil prop (schimitar??) it is 2 blade aluminum. He reported several knots more SPEED. And the spinner is sexy as well!

If it were me, I'd go with the fastest one

I think the whole thing was something like $8K

[skyking]

I just put on the new Hartzell "top prop" scimitar and the difference is amazing. Quieter, faster and one heck of an increase in climb.

As a Mooney Ambassador i had a chap named Gunter out last weekend and i he could not believe the climb rate or how quiet it was.

Total cost for prop, hub, spinner installation was around 13K canadian.

[67M20F]

what kind of DA do are you taking off from and what do you see for a climb out?

 

Looks like most say a hartzell but i  was told that the strait three blade hartzell is about the worst performance out  there right now, its done ok so far with us but just looking for more performance.

[skyking]

I am at 2500 ft ASL and i can get 2000 ft per minute easy.

I did 3000 ft per minute starting at 140 knots and it held it until i hit about 95 kts. at starting at 4500 ft.

Mine is the 2 blade

[Rustler]

The MT 3-blade costs about 10.5-11 AMU, plus installation.

[67M20F]

Ok here are some numbers from stockten propeller, McCaully scimitar-10250, MT scimitar-11,650, Hartzell strait three blade-9,250

[Immelman]

I should correct my staement above: My firend got his new schimitar prop & hub for his C for $8K because of a discount related to the prop hub AD.

[KSMooniac]

I agree with what Jim said.  You should be able to find an airworthy used prop for ~$2000 I bet, and that might be the smarter choice now if it allows you to keep your plane.  You could always upgrade to a new prop down the road and re-sell the used one...perhaps for the same money.

Last year I got a good discount quote on an MT from a distributor in MI or WI or somewhere up there...in the neighborhood of $9k IIRC outright.  There are usually Sun-n-Fun specials too on those.

Is there insurance involved with this?  If you're having to pay out-of-pocket, I'd be more worried about the engine tear-down inspection as it will cost more than a new prop, especially if damage is found.

[67M20F]

Insurance will be covering the cost, to replace the old strait three blade hartzell, the quote that they got from the original shop was 10,050, I can get a McCally scimitar for 10,250. So it seems alot better to get the scimitar.

I cant buy out my partner, just now way of doing it, thats why its still in UT. What prop is hung on the front of the airplane wont make any differance.

If he decides to sell it, then I think it will help it sell with a scimitar prop. Not for more just make it more attractive.

 

Thanks for the advise guys, surprising that nobody seems to like the McCaully.

[KSMooniac]

If you're hell-bent on getting a 3-blade, I think the MT is the absolute best choice...lighter weight, smooth operation, and likely longer life.  The cost will be the same or less from the figures you just quoted on the metal props.  I'm likely going to upgrade to the MT from my 2-blade McCaulley one of these days as I think it is that good and worth the money.

[67M20F]

Like I said, taking off from 11K DA airports all summer, the three blade I think is the best climb.

The only thing I don't like about the MT is that if you need any dressup then you have to go to a prop shop, at lest thats what my A&P said, and with an McCulley any A&P could do it, he also said that the McCulley three blades he has done and maintains have had no nicks at all in them he said that they won't pick stuff up off the ground like most props will.

If I thought that I could get the climb out of a two blade that I can out of three, then I would go for it, just don't think I can.

[KSMooniac]

The need for dressing with an MT is greatly reduced since the leading edge is a piece of stainless steel, and thus much tougher than the aluminum props.  I doubt you would ever need to do anything to the MT short of a prop strike or other impact damage.

My 2-blade McCauley has had plenty of nicks and dressing over the years.

[67M20F]

Here are the pics, makes that nose gear look strong, it must have been one hell of a hit!!!!!!

[skyking]

I think the scimitar prop will give you the same climb rate as the 3 blade.

I am very impressed with the climb increase i got with it. I could not justify the extra grand for the 3 blade.

From what i can see the 3 blade only cuts down on cabin noise and does not really give much of a performance increase over the 2 blade.

[KSMooniac]

The 3-blade metal props on the market for Mooneys should not cut down on noise since they are the same diameter as the 2-blade options.

[skyking]

I was told by my mechanic that reduction in noise is one of the benifits of the 3 blade. I have no data to back that up.

My new scimitar is actually shorter than my old prop and i picked up almost 2" of ground clearance. it does not sound like much but on some of the tie down areas of some airports here in Alberta every inch helps.

  

[67M20F]

I will gain about 1.5in of ground clearance, I think the three blade that was on there was 74in.

The McCaully is  supposed to be about 71in.

 

[KSMooniac]

Well, I might have learned something new then if the McCauley is indeed a smaller diameter...I remember looking at STC's a year or two ago and all of the 2- and 3-blade props (except the MT...don't remember) were 74" diameter.

[KSMooniac]

Here is the MT spec sheet:  http://www.mt-propellerusa.com/pdf/stcflyer/FL034US.pdf

71" diameter, 46 lbs.  Stainless steel leading edge strips...that is what I will choose whenever the time comes to upgrade.
