    Bill & Group, We overhaul air compressors here. We are also re-sleeving the Stage I heads. We have not come up with a suitable fix for stripped threads at the outlet valve port, though/ The hole is asymmetric, so you have more material on part of the radius than others. Helicoil is not a viable option, unless someone else out there has had success. If anyone is wondering about our support of the Yak & M-14P community, here are some of the things we do: M-14P: - Major repairs including prop strike/hydraulic lock teardown - Full overhaul - Accessory overhaul: Magnetos Carburetor Fuel Pump Oil Pump Prop governor Air compressor -Compressor shear coupling repair - Cylinder repair: Guide replacement Valve grinding & seating Exhaust port repair New, M-14P, Inc. rocker covers -Automotive spark plug adaptor kit -Nosecase seal replacement ****Flat rate with parts and labor -Magneto modifications Rewound coils with external capacitor High performance auto points conversion -Hose fabrication Airframe: -Hydrostatic testing of air bottles -Electric trim system: Ailerons and elevators -Tach Board for EFIS System - Pneumatic system component overhauls -Flap & landing gear actuators -Flap & gear valves -Uplock cylinders -Fabric - Coming soon: New Manufacture Fuel gauge and sending units Propeller: -Prop hub overhaul -Static balancing -M-14P, Inc.

    From: "Bitterlich, Mark G CIV Det Cherry Point, MALS-14 64E" <mark.bitterlich@navy.mil>
    Sam, Understood on how the type of flying impacts the reliability of propellers. What I am honestly interested in is the written information that relates to the tear down inspection intervals recommended by the manufacturer officially and in writing for either the blades, and/or the hub, both of which I refer to as "the propeller". You also said: "If you fly hard airshow or competition aerobatics, the 250 hours / 1 year would definitely make sense." What defines "hard" air show aerobatics? Are we talking gyroscopic maneuvers? Are we talking snap rolls? Just what exactly? Competition Aerobatics spans the realm from Sportsman, to Unlimited with a wide margin in the middle. Whirlwind obviously must have a set policy where some inspections might be "required" and some might be "recommended". What I am looking at here is a pretty hefty price tag if you purchase the blades, required hub, and ..... does it also require a different prop governor? In any case, before I plop down 15-18 K$ on a new prop assy., I'd like to read the fine print. Not trying to put anyone on the spot here, I just think the original question is apt, and I am still not quite sure of the answer.

If I recall correctly Whirlwind indicated that the limiting element is not the blade but the hub - I believe this would be the case with the other manufacturers also. If you fly hard airshow or competition aerobatics, the 250 hours / 1 year would definitly make sense. I see your point but with the type of flying I do, formation and moderate aerobatics, I'm not real concern about the reliability of the hub. The nearly 1000 hours I have on their hub on my older prop (same) gives me good confidence that it 'll work tomorrow too... :) Sam Sent via the Samsung Galaxy S II Skyrocket, an AT&T 4G LTE smartphone. -------- Original message -------- Subject: RE: Yak-List: Re: Flight Review Video - WhirlWind Aviation 3-Blade Propeller From: "Bitterlich, Mark G CIV Det Cherry Point, MALS-14 64E" <mark.bitterlich@navy.mil> CC: Sam, I am curious. When I go to their web page: http://www.whirlwindaviation.com/props/400cmseries.asp Under "Specifications" I see this: "Tear Down Inspection: 250 hours or 1 years" In the owner's manual I find this statement: "7.1 Teardown Inspection Schedule Refer to the original propeller data sheet for recommended teardown inspection schedule. If the original data sheet cannot be found, please contact Whirl Wind Aviation directly to confirm the recommended schedule for your propeller." So, it appears rather vague to me just what the tear-down schedule is when approached by a new potential buyer such as myself. Do you have a copy of the "original propeller data sheet" that actually gives the recommended teardown inspection schedule? Recommendations by owners are of course welcomed at all times, but all props have some kind of official life history inspection schedule. Of course, anyone can contact Whirlwind directly for a verbal answer, but I sure would like to see something in writing.

No, it is not necessary or required to remove once a year and this is nowhere in the operations manual that came with prop. If you fly continuiously heavy acrobatics they recommend inspection every 250 hours. I fly moderate acro and don't expect inspection before 500 hours. I suggest you call whirlwind directly and speak with Jeremy ans say hello from me :) Feel free to call me if you need more info. Ill be glad to help.

The prop looks fantastic. Is it true that it has to be removed and inspected once a year? I am weighing up between the Whirlwind and the MT, and the requirement to pull the prop and send it to a Prop Shop every year irrespective of hours flown seems a little onerous. What do you think? Cheers Egon. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=378371#378371 ~,g(MGqz{nrf ~,gky x ojja{nrf

    Subject: MT 3 Blade Propeller Food For Thought when choosing a prop
    From: "Dale" <dale@frii.com>
    Just a note about the MT propeller. Up to one third of the MT blade can be damaged and still be rebuilt by MT to overhauled like new condition for 1/5 the cost of a new blade. Can anyone else claim that. I know . Been there did that. I was impressed at the fast turn around as well from Germany. Not sure if a carbon or full glass blade can withstand that and then not cost $5K per blade to replace. As well as putting a higher load and chance of damage to the engine and low vibration transmission . Read this topic online here: http://forums.matronics.com/viewtopic.php?p=378508#378508

    Subject: MT 3 Blade Propeller Food For Thought when choosing a prop
    I sell MT propellers, and therefore I am very biased in favour of them. But, to my mind, there are two critical issues that people should consider when buying a prop: MT props are fully certificated, and having once had propeller failure on a non-certificated prop, I can say that it is something you never want to happen! Virtually all the competitors at the last 10 world aerobatic Championships used MT propellers, which must say something.

    I made the call, (440-275-1540) and talked to Jeremy. Some points to consider (at least for me) : THIS IS AN EXPERIMENTAL PROPELLOR 1. As such all inspections listed are "recommended" and not mandatory. Whirlwind will send out a "Service Letter" if an inspection moves into the high priority category. In my mind there are pro's and con's here. Lots and LOTS of good things are involved with certified props such as MT models. But an Experimental Prop is the same as an Experimental Airplane as far as the FAA is concerned, which can be a good thing in certain situations in certain "Regions" of the U.S. Just saying. 2. As of TODAY, the recommended tear down period has been extended to 400 hours/5 years. Either or. Again, this is a RECOMMENDED tear down period, since it is an Experimental Prop, this recommendation does not carry the same weight as it does with a Certified Prop. I.E. You are not required to comply with it, but you're not too bright if you do not. Price is about the same as the certified MT props. I did not question or discuss blade repair issues or vibration dampening. Jeremy pointed out some YouTube videos of a Pitts S12 and other aircraft running this prop. Very impressive. I do have a general question for the folks flying the Whirlwind props on M-14 engines. How did you folks decide to take the leap and go with this prop as compared to say the MT series? Did you pay full price for these props, or did you receive a discount for acting as a test bed?

    Subject: MT 3 Blade Propeller Food For Thought when choosing a prop
    A few years back, during AirVenture, Ray Gage ran over an orange cone out in warbird parking with his -TW with an MT. His MT prop sustained damage on one blade. The MT rep at Oshkosh, told Ray that single blades could not be replaced, they must be replaced as a set of three. Further more they said that the prop hub needed to be examined as well and they offered to do it. I observed the teardown, one of the plastic pitch change blocks had dented the aluminum rub plate. MT said it was not serviceable and charged Ray for a whole new prop. It took a while to get the prop. After seeing this, and the type of customer service Ray received, I decided to forgo purchasing an MT prop. Craig Payne

    Propeller
    From: Warren Hill <k7wx@earthlink.net>
    Mark, I was one of the first users of the WhirlWind 2-blade composite prop for the M-14P back in 2010. Paid full price and have been very happy. The only down side of being an early (first) adaptor was determining the optimum blade angle. The original setting only gave me 82% power on takeoff. Through a little trial and error ended up at 17.5 degrees and it has been a delight ever since. Can't say enough good things about this one.

    That was the old style props not the new computer generated propellers. Things change. New propellers can replace one blade. My Tw has the new propeller design. They changed somewhere in 2003. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=378541#378541

    From: Herb Coussons <drc@wscare.com>
    I have had excellent experience with MT in the US. I have had typical short, uninterested types of discussions with the Europeans. So not surprising to hear of Ray's experience with MT reps at OSH. The local MT shop gets 2 thumbs up. 6-7 years ago I also hit something at OSH and dinged one blade. In less than 24 hours I had a matched set of blades overnighted from MT USA in florida, my local MT rep did the tear down and rebuild and the prop was back on the plane flying the same day.

    I remember helping with a yak that had a prop strike at Oshkosh. It hit a cone that had a pipe in it driven into the ground. The local MT rep didn't have a prop nor did MT USA in Deland. I was asked by either Coy or the MT guys in the booth if I had one in stock in FL. I did and we had it shipped up to Oshkosh to get him going. Cliff Coy, "Mr MT," Gerd Muhlbauer, and I installed it at the show for the owner. Seems like pretty damn good service to me. I then ordered a replacement prop for the airplane I had that prop for. So I took the delay instead of the yak owner at Oshkosh. Sincerely, Kevin Kimball, Vice President Jim Kimball Enterprises, Inc.

    0A3 does have patrol and that's where we'll be meeting up with "Lefty" because its right next door to him. As for C16 I show a $6.41 price, but Frasca usually give us a discount for stopping by. TAZ is a little far west from a straight shot north. And way out of the way for Lefty. HXF sound like a good stop to tank up ($5.15/g) before OSH. So looking at : Me Chevy & maybe Smily FD44 to OPN Pickup Snookum, Lefty, & Goatboy at 0A3 5or6 ship to C16. 5or6 ship to HXF. 5or6 ship to OSH. We'll plan on leaving FD44 right after sunup to OPN. Takeoff + 2:00 OPN to 0A3 = 1:30 0A3 to C16 = 2:06 C16 to HXF = 1:30 HXF to OSH = :20 Goatboy maybe you can meet up with Snookum at MSL than to 0A3. How's that sound guys?
