It might be useful to all owners. Thanks Nico After weeks of trial and error, I have finally reached a point where I can safely say that clocking the prop doesn't just make a difference, it makes ALL the difference. Several weeks ago I set out on a mission to run to ground a vibration in my RV-8. An IO-540 C4B5 with a Hartzell 2 blade prop. There has been a vibration that I would characterize as objectionable. Common on big engine Rockets and RV's. The lower the RPM, the more objectionable it was. I was able to instrument the plane and do some real tests and get real results with real data. The net of it is that by changing the prop clocking, I was able to improve my vibration by 83%. And no Im not kidding. You can read all the details here. http://www2.mstewart.net:8080/super8/index.htm I captured a lot of data. I sure hope others find it useful. I have a new plane as a result.

I've been thinking the Thielert turbo-diesel in the 500 series would be a great match. The right power, the right weight, the right fuel, and its blown to boot. (Too bad it can't possibly sound as good as a big block chevy.) With engines like the Thielert up and coming, and small turbines in development, I wonder how far the Orenda can get? Hard to imagine a realistic scenario that has I0-540 owners modifying airframes to put in a radically different gas fueled powerplant to replace something that is so good at what it does year after year. ----- Original Message ----- From: nico css To: commander-list@matronics.com Sent: Tuesday, April 17, 2007 2:11 PM Subject: RE: Commander-List: Orenda Rises Again I saw Thielert is planning a 350 hp diesel engine.

I suspect the Theilert Centurion 4.0 would be the better bet if I was going to try for an STC, but Theilert seems very uninterested in promoting STCs currently (this came from the company itself). Apparently they are selling all of the engines they can produce, and want to focus on Quantity or, even better, OEM relationships (like Diamond or Cirrus) where they can get the OEM to commit to ordering lots of engines in future by contract. Of course, in the airplane biz, such contracts don't last very long, only as long as the company's next chap 11 or acquisition, but that's what they're doing.

That would be something cool for the 500 series, don=92t you think? http://www.planeandpilotmag.com/content/2006/apr/diesel_skylane.html http://www.aflyer.com/atlantic_flyer.year/atlantic_flyer.oct%2006/OCTpdf/ page11.pdf ------------------------------------------------------------------------- --- From: owner-commander-list-server@matronics.com [mailto:owner-commander-list-server@matronics.com] On Behalf Of Bruce Campbell Sent: Tuesday, April 17, 2007 10:24 AM To: commander-list@matronics.com Subject: RE: Commander-List: Orenda Rises Again They discussed a future v6 several times before they went belly up. I don=92t know what the plans were about the type of v6. There are plenty of v6s in the auto market, but I do remember the GM 90 degree v6=92s (like the Buick 3.8 liter, which was a 75% slice of a V8) were rough until GM put a six-throw crank in them. After that they seem to have been OK. Presumably Orenda would do something similar to the GM exercise. But that is all speculation.

I was unaware of the fact that Dick and his predecessors had this in mind. Just curious, as v-6 engines are usually problematic.

BUT, my question is , do you think it would work on the smaller 500 series airframe? The wing root being closer to the fuselage might be the downer... Wonder what 600 hp per side would do to a 7400 max gw airframe... Straight up???
