That's a very expensive prop, but looks very very cool.  Are you referring

to the 3-blade composite prop?

Patrick - Don't go there.  The Hartzell guys were evasive at Arlington

and downright rude at OSH.  They want $27,000 for the three blade

composite which is now Type Certificated for the Cirrus SR-22 G2 and G3.

Which by the way runs on a Continental IO-550N or TSIO-550 from Tornado

Alley.



Several airshow performers have a more robust composite three blade on

IO-540s running higher compression pistons at upward of $35,000.



Their official answer, "Hah, If you want a three blade Hartzell for the

IO-540 then get VAN to personally request it otherwise.... Its not for

sale on kitbuilts to individual builders".



I came away licking my wounds and swearing that Deems and those who have

gone with AeroComp and an American Propeller three color finished paint

job have chosen wisely.  If necessary, I kept their business cards in my

"Do not ever frequent business with these guys".  Just my opinion.



Their two blade aluminum scimitar is the best you can get for the RV-10

if you want to climb slower (1700 fpm) and have VANS blessing.

Jessie, I don't know if Hartzell make a composite propeller, I suspect

that their's would be metal.  I think you might be referring to the MT

three-bladed propeller?



I don't know about the 'cool' aspect Jessie, but would rather gain an

increase in climb performance and an increased ground to propeller tip

blade clearance.  We have a predominance of unsealed Authorised Landing

Areas (ALA's) here in Australia and stones play havoc with our

propellers.  Going to a shorter propeller would be very advantageous.

I didn't know one could purchase the three bladed carbon Hartzell (one used 

on the turbo cirrus). I asked the rep at the AOPA convention and was told 

(unofficially- but honestly)that they were expensive; at the time, only 

being used "custom" for the Cirrus; and that there was no real advantage 

anyway to the blade for a RV-10 versus the 2 blade. "Advantage" being 

performance and weight was slightly better than the 2 blade but he couldn't 

justify the additional costs when there were other composite 3 blades that 

were far less expensive anyway.

Thanks John.  Price is an obvious barrier and when applied against

benefits, it looks like the standard two-bladed affair will have to

suffice, unless as you indicated, the AeroComp or American propeller

options are pursued.  I'll just have to take care with the stones!



Thanks for your prompt replies gents.

Patrick;

Your subject line states "Three Bladed Hartzell", we are all responding 

accordingly. There is indeed a three bladed carbon reinforced blade, 

http://www.airframer.com/news_story.html?release=796 and Jesse is right , it 

is cool!



Don't confuse this with the MT composite blade. The cost is more in the 8-9K 

range for that blade after one gets it from Germany and assembled.

Paul Grimstad did quite a discussion with AeroComp on blade repair and

leading edge replacement for exactly your issue.  I think Paul is now

sold on Aero Composites but then he will have to respond.

This blade was specifically designed for the GA market but that means

certificated (TCDS) manufacturers, not for Experimental Kit Built -

hence the brusk treatment.



They said ask VAN to request it or go away. I suggest we ask VAN to

supplement the MT choice for three blade composite choice.

Correction, the second engine choice was a Turbo-Normalized TNIO not the

TSIO as I unfortunately typed too fast.



I have several pictures of multi color blade paint schemes which can

match airframe designs if readers want to consider an AeroComposite.

Visit Deems site for his specific finish.



Hartzell makes a great two blade metallic but I find value in three and

the dampening effect of composite.  The replaceable nickel leading edge

and ability to correct rock chips is a big consideration.



Wouldn't it be a perfect world if VANS would offer the Hartzell 3 blade

composite to RV-10 builders??

I don't know if this is just for testing or actually available for

customers, but I saw the 3-blade Hartzell on an IO-540 Maule, I believe,

when I went to visit the factory recently.  It definitely is the coolest

looking prop I've seen on a small plane, but for 3 times the MT price and 4

times the Hartzell 2-Blade metal blade price, I don't see it being used a

whole lot on RV-10's or Maule's, even if it does become available, although

some would likely fork over the cash to have something that "special".
