Hi
As some of may recall, I took the path less travelled and put a 3.6L Subie on my -10. Over the past year I have been quite happy with the performance that is to say until I had a piston problem. As I a) haven’t been able to determine the root cause of the problem and b) determine how to prevent it, I have decided to retrofit an IO540. Although there many 3.0L Subies flying on small RV’s, there are not many 3.6L engines which complicates matters.
I plan to get a Barret engine but still need to decide on a governor / propeller combination. Van’s Hartzell seems like a good choice especially from a cost perspective but I would be interested in knowing the other options. From what I have read, 2 blade props are best below 300HP but there also seems to be a number of 3 blade options as well.
Any info appreciated.
Cheers
Les

Just for reference. I am very happy with my Hartzell IO-540 (260 HP) combination. I fly out of Utah, field elevation 4460 and have operated hot and heavy out of other higher altitude fields. Climb performance with that combination is more than adequate. Having not done any side by side comparison on 2 vs 3 blades I do not know the performance differences. I think there is some use full information in the archive on that type of testing.
One thing to note, I would not like anything that made getting the lower cowling on and off more difficult.
The three blade props do look sexy and fast……

The Van’s two blade Hartzell blended airfoil is, my opinion, the best performance value out there.
For governors, recommend looking at the PCU-5000. I’ve used them on two RVs and they have been flawless. I got both via group buys on Van’s Air Force at significant discounts.

I have a Barrett IO-540. What an engine!!!
Couldn't be happier. If you use their cold air induction you will need the Show Planes cowl which works very well.
I have a MT three blade prop and it seems to be almost as fast as the Hartzell blended two blade
But it really out climbs it. Also a function of more horse power.

THIS IS HOW THE ENGINE WAS DESCRIBED TO ME:
“…. purchased the engine and prop from Westair International Company, Monument, CO 80132 Jim Cullen is the owner. (719) 481-2286 He sold a number of these engines and was recommended to me by Murphy. They thought this was a perfect engine for their plane. I called a fellow who bought one from him to check up on his transaction. He was very pleased with Jim and the engine and prop. (His name is John Knutson, Chicago, (312) 642 0335 home (312) 383 1300 x 104 work) I believe he was putting it into his homebuilt. I haven't talked to him in ten years so I don't know if the numbers are still good. The engine arrived as promised and is complete with magnetos, harness, fuel pump, Bendix injection system, alternator and starter. It is preserved, and includes platinum spark plugs (not installed--the plug holes have the things in them that absorb moisture--I can't remember what they are called!) There are three tech manuals also. It is still in the shipping crate which has always been in my heated shop. I looked in it today and it looks good. The IO-540 G1D5 engine serial number is L-9927-48. It is rated as 290 HP, max rpm 2575. The Hartzell Propeller Model HC-92WK-1DW S/N AC-206 The engine has a total of 799.22 hours since new. It has 5.43 hours since overhaul. The propeller has a total of 731.12 with 2.12 since overhaul. There are two complete log books for the engine and one for the propeller.
My concern before buying was that they came out of an IAR 823 airplane which was a plane used by the Romanian Air Force! (I Googled it and it looks like a Mooney to me.) I checked with several engine building people (including the company that overhauled my Cessna engine) who told me the overhaul facility in Romania is noted for quality services. (BOAC had them do all their engine maintenance.) A fellow on the Murphy group, George Coy (who now sells M14P radials and was building a Moose--put this IO-540 in his plane. I asked him why not use one of his radials and he said he was going to put it on floats in Vermont and could not have any oil dripping into their pristine lakes. I guess coffee cans wired under the jugs does not meet environmental standards for catching 100% of the oil!
The log books are all in Romanian but I had someone go over them with me (they spoke Romanian) and they are very detailed and complete. I was going to sit down with this person and rewrite each entry but haven't yet. I got a new English engine log from Jim Cullen--I'm not sure it is really necessary to translate the old ones. I feel comfortable with the accuracy of the logs and the work that has been done. A mechanic where I get my Cessna serviced was interested in using the engine for his tow plane--checked out the engine and logs, said it looked good but then found his mounts or something were different and it wouldn't fit. He offered my $20,000 for it! (I should have paid for his new mounts!) Hope this is the info you needed--I think it is the right motor for the Murphy. I've watched a friend mess with a M14 radial in his Moose but his struggles with the cowl, oil leaks, air start, parts, mounts and extra fuel burn, etc. etc. convinced me a good old 290 HP Lycoming was what I felt most comfortable with.”

Les, when I bought my prop and governor a year ago it was around $12K
with shipping for the two together from Jim Ayers. I was notified by MT
that something had happened to Jim, so both came direct from MT in Miami.

I agree the 2 blade is best. I have had a MT and now fly w/ the vans 2blade. FOD caused so much damage to the MT I had to send it to Florida for O/h. Ins pd for 1blade. Had to replace all.very $$$. KISS. You'll be glad you did . Lost climb rate of 500fpm but gained 5gph . I fly out of Ruidoso.6800ft no problem with Vans prop. N661G kcrp. 750 and loving it. Robert Brunkenhoefer

Just for reference. I am very happy with my Hartzell IO-540 (260 HP) combination. I fly out of Utah, field elevation 4460 and have operated hot and heavy out of other higher altitude fields. Climb performance with that combination is more than adequate. Having not done any side by side comparison on 2 vs 3 blades I do not know the performance differences. I think there is some use full information in the archive on that type of testing.
One thing to note, I would not like anything that made getting the lower cowling on and off more difficult.
The three blade props do look sexy and fast……

Hi
As some of may recall, I took the path less travelled and put a 3.6L Subie on my -10. Over the past year I have been quite happy with the performance that is to say until I had a piston problem. As I a) haven’t been able to determine the root cause of the problem and b) determine how to prevent it, I have decided to retrofit an IO540. Although there many 3.0L Subies flying on small RV’s, there are not many 3.6L engines which complicates matters.
I plan to get a Barret engine but still need to decide on a governor / propeller combination. Van’s Hartzell seems like a good choice especially from a cost perspective but I would be interested in knowing the other options. From what I have read, 2 blade props are best below 300HP but there also seems to be a number of 3 blade options as well.
Any info appreciated.
Cheers
Les

Please explain the 5gph gain????
No question a 3 blade will be more expensive to repair and overhaul.
I would expect vibration and noise to be somewhat less with the MT.
Agreed climb is very good either way.
The MT governor is less money than the PCU-500. Haven't heard any strong
reason to choose one over the other.

Now that we are on same page......
I vaguely recall a few early builders doing some prop comparisons, but don't know if they are in the archives. I know Van's did some comparing props for 2 seat models, but I don't think there is anything handy for the RV-10. Seems like Rob of AFS might have compared the MT and Hartzell, or maybe it was Hartzell 2 blade vs their 3 blade carbon fiber.
I certainly would be interested to see some data as to prop performance under controlled conditions, i.e. wide open throttle with same or identical engines and cowlings, perhaps power settings between two planes holding formation, etc.
Seems like our EFIS panels could collect the data while pilots just held position on each other. The usual figures I see on other makes with same question are 0 to 5 kts speed advantage for 2 vs 3 blade props depending on variety of 3 blade. Usually the aluminum variety give up more because they cannot optimize prop airfoil for strength/machining limitations, and the composite come closer to equaling the 2 blade on speed while doing much better on climb.

I’m not sure that I can offer a great deal here as it was on a Cessna 310. What I noticed was an improved climb and virtually no difference in speed. The real benefit was that they were infinitely quieter at full throttle or cruise. I do plan on using a 3 blade on the RV-10 that I want to build.

OK, here's my 2 cents.
When people are comparing the props and give numbers on speed differences, that is wide open throttle and rpm.
I've raced my 3 blade MT against 8 RV10's, 7 with 2 blade hartzell's, one with a 3 blade, but not MT, and beat them all. Ok, so I have more ponies.... but it's smoother, climbs at least as well, and who flies flat out all the time anyway. I'm able to cruise at roughly the same speed, but am able to run lower MP (18-19) and RPM settings (2,000 to 2,200), and have found no other 10 that gets as good of fuel mileage as I get. (9.5 to 10.3)
Latest test was on a long trip in the 10 with a brand new RV8 with a new IO-390.... at 10,500', I heard those wonderful words from the 8 "you're pulling me".
Just remember if it seems smoother to you, it's easier on everything, the engine, the airframe, the avionics, etc.

I went to the Northwest Territories with my MT prop and could not go to kuglutuk north of the arctic circle because the gravel runways might damage the prop and there was no way to file them and fly out of there. They have that limitation. IMHO

When people are comparing the props and give numbers on speed differences, that is wide open throttle and rpm.
I've raced my 3 blade MT against 8 RV10's, 7 with 2 blade hartzell's, one with a 3 blade, but not MT, and beat them all. Ok, so I have more ponies.... but it's smoother, climbs at least as well, and who flies flat out all the time anyway. I'm able to cruise at roughly the same speed, but am able to run lower MP (18-19) and RPM settings (2,000 to 2,200), and have found no other 10 that gets as good of fuel mileage as I get. (9.5 to 10.3)
Latest test was on a long trip in the 10 with a brand new RV8 with a new IO-390.... at 10,500', I heard those wonderful words from the 8 "you're pulling me".
Just remember if it seems smoother to you, it's easier on everything, the engine, the airframe, the avionics, etc.

So as I see it the answer is.....
All these props are close enough to each other that only a direct A-B test (change props on the same airplane) can tell the difference. So far as I see only Robert has actually done that, and he seems to confirm the folklore:
2 blade: least expensive, fastest cruise.
3 blade: best climb performance, quieter and smoother.
Fro the record, I have the 2 blade Hartzell and Hartzell governor straight from Vans, and am happy with both.

I too have both Hartzell prop and gov from Vans. No complaints from me, but I only have about sixty hours at the moment.
