Hey Guys,
Late yesterday I talked with Bill C. of Whirlwind. He is involved with the testing of their propellers including the HRT74. Bill tells me that the new HRT74 prop is designed for 205 hp or above. He suggested that if you have an HRT74 ordered and do not meet this minimum hp you should give Whirlwind a call.
Thought you folks needed to find this out now.
Cheers,
db
Word from whirlwind is the spinner is drying overnight and should ship tomorrow. I'll post pics asap!
No Whirlwind prop yet.
Last email said hopefully.....the end of this month.
They said still had others in front of us.
Ordered at SNF.
This week will be 20 weeks.
Paid deposit with order.
Have not been asked for balance.
No shipping info.
Invoice date 4-13-17
Order # 3263
WW has been responsive to my emails and just keep pushing the completion date out, email by email. Explainations of just being overwelmed by orders and repairs etc. 8 weeks, 10 weeks, 12 weeks, few more weeks, end of the month...
Not a problem for us as we are still happily flying the Hartzel prop. It does make us wonder about what happens, once we install the WW and sell the Hartzel, if we have a problem with the prop and have to wait and not fly.
To be clear......I am not vendor bashing, just stating the facts so others in the same position or curious can be in the loop.
Upperdeck.....thanks for posting your info...somehow it helps.
Thanks Chris......good info.
Bob FYI , I spoke with WW earlier in the week and was told the hold up now is a supplier that does some completion to the "studs". My prop blades are apparently completed and mine is #3 in line to ship and was estimated another 2 weeks.
I hate to contribute to the thread drift, but I did get my HRTprop from WW about three weeks ago. She's a beauty!

Bob, mine arrived last week and I am trying hard not to unpack and admire it until installation time.
Bob, I am 3261 and mine arrived last Thursday, 10/19. Becca should be calling you for payment any time now.
Thanks Chris........good info.
We will get the checkbook ready..![]()
Bob,
Am I reading this invoice correctly? Twelve THOUSAND bucks for a prop?

With now almost 170 hrs on the overhaul, my WW 200RV is NOT losing any grease at all. That issue does indeed seem to be solved by the Viton O-rings.
With almost 470 hrs total on my prop, it still looks like new, except for the red oval decals, which seem to take a beating.
As a test I would be interested in is a ground pull thrust comparison
If interested I'm close enough to come over and help.
We have had some fitting issues, but getting them resolved.
Inital numbers are good/faster.
Main thing is 18 lbs lighter......prop and spinner combo.
Very pretty prop too...
I say this and it sounds hollow but it is true. A prop up until now has been a hunk of wood or metal with various paint jobs.
This prop has a finish that would rival the best paint job out there. Almost TOO pretty. One really has to be careful using powerful tools to torque nuts and safety wire etc around this prop.
Normally a prop just gets a cleaning or a wipe down, etc, but this prop begs for wax and to be taken care of.
Bob, any additional performance numbers on the prop?
Thanks, Brian
Bob, I am sure you have considered the effect on cg that this change will cause.
Several hundred hours ago, I switched from a 200rv to a hartzell Aluminum to gain 19 pounds on the nose. The cg moved from tending towards aft to right in the middle of the range. The flying characteristics are substantially improved. a 6 with aft range cg?s can be very sensitive in pitch, have tendencies to bounce landings and limits aft baggage in a meaningful way.
Hope you are not going there.
Hi Krea,
I don't have the engineering expertise of Steve Smith but I do have real-world experience with both props. I flew my RV-8 with a WW 200RV for about 1500 hours. I was given a Hartzell composite, wide blade prop when Hartzell sponsored our Team AeroDynamix.
Ron,
A friend of mine is contemplating the change from the WW to the Hartzell composite CS prop. When you made this conversion, how well did it fit with your existing cowling? Or did it require surgery on the cowling for fit?
Taking 18 lbs off the nose seems like a wonderful thing.
It also made our wallet thinner.![]()
I am in the process of converting my RV7A from a Fixed to a C/S prop. I want to go with the Hartzell 74" composite 2blade. Apparently a "stock" Vans cowl accepts the Hartzell (or anyone else's) hub with no problem. However my Sam James cowl is 1 3/4" longer than stock Vans. When using a fixed pitch prop you use a 2 1/4" spacer between the crank/flywheel and the prop hub. I use a 4" spacer on my F.P. Sensenich. I have been unable to determine if Hartzell makes a hub that will fit my Sam James cowl. Vans doesn't seem to know the answer, nor does Sam James. I'm yet to speak to anyone from Hartzell. Has anyone on the forum ever installed a Hartzell composite C/S prop on a Sam James cowl?
Any thoughts about overhaull experiences and costs comparing the 3?
