I am going to fly my RV-10 at the same weight and compare the prop directly  with another local unpainted RV-10 with the same engine and ignition.

  

 We did fly with Randy Debauw for much of the trip to Oshkosh so I do  have some idea on how it performs. 

  

 Randy has the older two blade Hartzell prop and was around 300 to 400 lbs  lighter than we were with my three kids and all their stuff that just had to go  to Oshkosh in the RV-10.  It looked like my RV-10 was around 3  kts slower, but climbed faster even with the extra weight. 

  

 The polished spinner is the same diameter as Van's stock one.

I spoke to Hartzell briefly this morning and asked about the composite prop. They said to check back in three months.

In less than three weeks, Rob Hickman should be able to give us all the

information we need. Quieter, Smoother, Faster Climbing, and lasts

longer with easier care and maintenance.  Now it's VAN that needs to

tell us the price.

Unfortunately, Hartzell won't say anything until they get the thumbs up from Van's.   Our chapter just did a factory tour and they spent quite a bit of time on the approval process on what they sell.   If you mention RV and it's not on the Van's approved list, they will ignore you.  :^(

Glad MT and AeroComposite don't take that stance.  Hartzell's loss is others gain.

This  is partly my fault as I have not finished testing either prop for them; it was  just too hot to fly it against Dan's RV-10 over the weekend here in  Oregon. 

  

Hartzell  will not sell a prop until it is approved by the aircraft manufacturer and Van's  will not approve the prop until they get test data from it.  To get a  reasonable price on the Harzell prop you are going to have to get it with an  OEM agreement, and that means from Van's.  Getting performance data to  Hartzell and Vanâ€™s is at the top of my list for the RV-4 and RV-10.  Hopefully,  Iâ€™ll  have data to them this  week. 

  

I  currently have over 70 hours on the prop in my RV-10 and I would not trade it  for anything.  Jennifer and I flew  it to Vanâ€™s home coming on Saturday and as soon as I shut it down we had a  number of people telling me how quiet it was when we taxied in.  We flew our neighbor (who has built  aircraft engines for years) home with us in the RV-10, and he was amazed at how  smooth and quiet the plane was with this prop. 

  

In  my opinion,  Hartzell is being very  responsible for  taking this stand  and we should give them the credit that they deserve.

Â  I wouldnâ€™t particularly blame yourself, if Hartzell really wanted a testing program they would have dedicated someone to it. Â Â Itâ€™s understandable to want to wait until they have their data but refusing to discuss a new product makes no sense to me.Â  They can discuss plenty of things like design philosophy, projected performance, construction materials, retail price.Â  Itâ€™s called marketing and is usually used to generate interest in a product even if it isnâ€™t ready.Â  From what Iâ€™ve seen and heard the only thing they have been generating are a lot of irritated people from being blown off when inquiring about the prop.  

   

Â  A year ago some guy from MT blew me off when I was trying to ask questions at OSH07.Â  I mentioned it in passing on the list and within a day I had a response from a US distributor and the president of the company in Germany apologizing and offering to answer any questions.   

   

Â  Just my $0.02, YMMV, yada yada yada

I keep hoping the price will be affordable, wife is bought into the three 

blade, just not an expensive one, which leaves only MT at this point. I have 

hopes but she is really not happy about the blow off last time we spoke with 

Hartzell.

Rob;

 Are you using a MT governor or the Hartzell governor with the 3 blade  prop?

 Any speed test done yet? max speed, climb speeds etc??

 Thanks!

Being I am one of those disappointed with Hartzell and their lack of  response, any response at all, I did receive an e-mail back from Kevin at  Hartzell giving me the latest. Rob is right..  it's his partially  his fault they wont talk until getting a final report from him and  approval from Van's to be an OEM. Basically everything Rob already  mentioned.

 The good news is that Kevin thinks they are close to finalizing the details  for Van's to offer the prop for the RV-10. Pricing was something they will leave  to Van's and had no comment on the range. Because Rob already has tested the  prop on a IO-540 Kevin mentioned that certification would already be completed  and hence leave little delay in being available for RV-10's once it became  avilable.

 Price is the only thing standing in the way now..

Not that it matters to all people, but the preliminary numbers

that Rob posted this week put the prop definitely behind the

MT for speed, and likely 10kts off from Van's 2-blade hartzell

numbers.



8500 FT

2450 RPM

Full Throttle

169-171 KTS True Airspeed

When buying a prop, there is NO one best choice.  Every prop

we can choose will have a tradeoff.  Price, smoothness, climb

rate, maintenance, weight or lack thereof, and looks.  Climb

speed benefits quickly wash away in cruise if the prop

doesn't cruise as efficiently, and vice versa.  Some builders

will want MORE nose weight, and some can't afford to have

any LESS nose weight.  So picking a prop depends on so many

individual factors that it may in fact pay to wait until some

other decisions are made before you buy one.  If you choose

an avionics and other options list that leaves you nose-heavy,

you could fix it with your prop choice.....or, you could

destroy your CG range by choosing the wrong prop for your

options package.



No, this post doesn't give you much of any useful info to

go on in choosing a prop...that's up to you, your styles,

and your configuration.  But, it would be nice to see more

good reports on the performance of the Hartzell, because

right now it looks to be potentially 8-12kts slower than

what Van's puts out for numbers.

Interesting,  I actually heard from one person who told me " I spoke to Rob 

Hickman at Oshkosh to get an idea of the 3-blade composite prop performance 

on his trip to OSH from Oregon.  He told me that he was able to keep up with 

is buddy that was flying an RV-10 with the 2-blade prop.  The difference 

being that Rob was about 500 lbs. heavier since he was carrying his family 

and luggage.  I think Rob was very pleased with the performance of the 

3-blade prop."



Rob is searching for that MT in Portland to do a comparo, but I figured if 

the information I received on Rob's trip to OSH is accurate that tells me it 

can keep up with a 2 blade.



Your points are good ones about prop choice.

Rob

Thoughts?

I know you have the 2 blade prop on your plane,  what are the tas numbers

that you see in thee same conditions.

I have been told the IO54 has the most torque around 2200 RPM.  I don't remember the source.



I have tested different RPMs and I get the best speed around 2250.  It kinda adds up, lower RPM has less drag.
