Just curious. Listed WW prop tear down inspections vary; 250 hours or 1 year, 350 hours or five years, 650 hours or 5 years, etc.
Point being, maintenance requirements are part of the decision tree. Carl |

WW Stories
I've had two Hartzells and two WW. I won't go into it here, but PM me and I will tell you about my experiences with WW and why I am a Catto flyer now.

Decision made
Sent the form to Van's this morning for the Hartzell composite with the extended M hub. Big bucks but should be a great prop on our RV-7A.
Thanks for all the advice and experiences. |
Interested in this too.

Hartzell v Whirlwind
Bob, I'm excited to hear the comparison of the BA vs newer WW. I'll definitely keep an eye on this thread as it progresses. I've heard the BA wins performance wise vs the older 200RV on the same aircraft.
My $0.02... My -7 with the Hartzell BA is perfectly balanced. It's almost impossible to load it out of CG. The plane is off the runway in a couple hundred feet and climbs like a beast. Plus, there are no aerobatic limits (no extension req'd) and no RPM limits with this combo. So, I'm very very happy. However, I flew through some decent rain last weekend and noticed some of the paint had eroded very slightly. I hear the nickel leading edge on a composite prop is better for rain and backcountry flying. Anyone with experience there? How is the W&B with a lighter prop? I also flew a -7 with a 3 blade composite MT prop which was a super smooth running combo -- almost turbine like. |
update
Just an Update as I know a few are watching the thread.
We have still not received the new 74HRT from WW. 15 weeks now.......and still no shipping notice. WW says they are very busy. |
Did you get the prop yet?
|
HRT
For what it's worth, I have the HRT on order also. I've been told it will be shipping this week. No tracking info yet.
|
Prop
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.:eek: 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. |
