Hartzell Top Prop Mod

[flight2000]

The problem with losing weight off the nose is it impacts your CG.  By how much, I'm not totally sure, but I'd rather lose the weight in the center regions somewhere.

I think the hub exchange was like 3 AMU at one point, but it has gone up since then.  I'll call when I get back in December and find out.

Russ lives in the rarefied atmosphere of "East of Edmonton."  That is almost like "East of Eden" only colder.

No joke. In the winter i can hold almost 2Kper minute to about 7 or 8 thousand feet. The speed will bleed off a little from 100 MPH down to about 90-95 MPH,but it is still pretty good.

I know Eldon was pretty impressed when we went out for a flight.

In the summer i can get about 1500 to 1600 a minute with no problem.

I did a search for any newer posts on this prop and found nada.  Does anyone have more recent experience with any of the spinner issues with these props?

This, imo, is a prime example of tinkering and modifying a perfectly trouble free OEM component, i.e. McCaulley, with another that has documented baggage, weight penalty and insignificant benefit over the OEM. 

Would some one please explain the logic here? Am I missing something?

The 2 bladed Hartzell Top Prop is for real. If you have to buy new and can get some exchange money for your Mac, it is worth the expense. I am doing it at next OH (my blades are shot and it is almost time). This prop is a great success, it is quieter, smoother, virtually AD free, great service history and support and it is a significant improvement over the OEM Mac's.

"Built on Honor", Baby!

My prop is being replaced during this annual as it's finally time to do it.  From what I understand, Hartzell finally fixed the problem, but I don't have the full details on exactly how they fixed it.  Guess I'll have first hand knowledge of that pretty soon. 

For me this is a Hartzell to Hartzell transition and it gets a better climb rate to boot.  Not like I was hurting in the first place, but it'll get up and go even quicker now.  It also gets a less restrictive operating placard compared to what I currently have AND no more recurring AD that's due every 100 hours....

Someone correct me if I'm worng, but Mac's didn't start showing up as an OEM prop until the mid 70's or later.  It was all Hartzell before that.

I think the McCauley prop showed up with the -A3B6D engine in 1977, for the M20J.   This engine has a counterweighted crankshaft and the yellow arc on the tach from 1500-1950 RPM.

Lycoming sells the 2-blade BA top prop as part of the STC for the IO-390.  They claim someting like 3 knots of cruise speed improvement.  Well, if the prop is worth 2 knots thats a heck of a deal.

I installed one of these on a 1965 M20E and owner reported a 3 mph increase at cruise, his came with an alum polished spinner, but had to be replaced within 2 months due to cracks, they replaced it with the white composite under Warranty.

the prop is very smooth and quiet at cruise.

I was one of the first to install the Scimitar/ Top Prop Conversion on my '70 E' back when they first came out. I can without a doubt tell you that is the one speed mod that i can feel the difference on. I gained an easy 8 MPH increase in speed (no BS), but I lost a little torque on the takeoff roll. It's a good trade-off in my opinion. Thats the good. The bad was the original Aluminum spinner. The design flaw was the torque pulses generated by the 200HP engine were too much for the attatchment points on the spinner...a spinner that had no bulkhead attachment. I was also the unfortunate victim of a spinner blow-up in flight which tore up my front cowling (and a few other options). All SB's had been complied with up to that point. I now have a short J . Anyway, that was the final straw for Hartzell and just after they issued the AD to replace the spinners with the composite on the 'E' models only. The 'J' models are fine because they have room for the additional bulkhead.

So there you have a little bit of spinner history for those of you considering the swap. I still stand behind my statement "It's the best speed mod I've ever done to my mooney"

One should also consider the current state of MAC/Factory and the fact that our props are OEM and not available directly from McCauley (if you have an early 201). To that end, it would be silly not to look pragmatically at alternatives. Hartzell has worked most of the bugs out and is in a better position to back up their product.

What?  Your Lycoming engine came originally installed on your Mooney, too.  Do you have to go through Mooney Aircraft Corporation (MAC) to get one of them or can you go directly to Lycoming?  They both have part numbers that were assigned by the manufacturer, not MAC.  With all due respect, John, and I'll gladly apologize if proven wrong, but this seems like nonsense to me.  McCauley is alive and well and as corporately healthy as far as I know as is Hartzell, and as far as I know their C214 props at least are still supported.  Possibly their C212 props as well.  Both Hartzell and McCauley should be able to support their products for the foreseeable future.
