Well, I don't plan to do any "serious"" aerobatics with my 50 anyway.
That's not a problem of the engine or the propeller, the plane is just too
old (and too nice and to precious - to me) to be flown hard.
And I am to old tooŠ
With 450 horsepower (even more now, with electronic ignition Š) I just
have the mere fun of outclimbing every other dude in the far neighborhood,
be it with Extra or Edge or whatever.
And I NEVER pull more than 5 G (it used to be different in the past, I
know).

Yeah Jan, you're happy with your MT prop.
But you never do any snaps, flat spins, tumbling or Lomcevaks with your
Yak 50. 
We've got the standard Russian V530 TA-D35 on our Yak-52 (and a spinner !)
and we have NEVER had any issues with it ... so far.
Perfectly statically and dynamically balanced (prop-engine-spinner).
Very smooth throughout the complete RPM range, from idle to full power
and every power/prop combination in between.
And we do A LOT of snaps, flat spins, tumbling or Lomcevaks with your Yak
52. [Wink]

We like to keep it simple.
"If it ain't broke don't fix it"
The only thing is that it "needs" overhaul every 6 years according to
the very strict maintenance rules edicted by the UK CAA for Yakovlevs.
Skycraft in the UK or Hoffmann in Germany do a good job overhauling
the standard Russian V530 TA-D35 2 blade paddle prop. 
Having said that, as reported by Richard in a previous post,
a lot of much better pilot than me (most if not all) fly behind MT
propellers,
"which must say something".
I'm just saying that a "good old" Russian V530 TA-D35 is certainly good
enough for most Yaks (50 and 52).
Best Wishes, Etienne.

Thanks Richard! I always wondered how it performs. Beautiful prop though.
Do they continue develoment on this F-W 190 prop, at Mullbauer's ?

In fairness to MT, that F-W 190 style prop is purely for show. It is not
suitable for anything but the most gentle of aerobatics, and gives far
less
performance than the standard MTV-9 with the - 29 blades.

The FW-190 blade was made for just that a scaled 190 built in limited production kit/experimental. MT also makes a scimitar blade as well. The Radial Rocket uses the scimitar shaped blade. You can get the Straight, 190, or scimitar blade for the MT. I asked for a paddle blade and they said no even though they build one for a scaled 51 in a four blade. The standard - 29 can be built to a number of diameters. Your choice

Yes, it's true - the FW190 prop performs well, even on "small" engine -50s like Tom's. With the "big" engine w/ over 475hp, the performance is amazing. As Cosmo states, the braking action of the FW190 prop is excellent - much better than the MTV3 or even the MTV9 w/ -29 blades. I agree with Cosmo - not much performance difference between the -29 and the 190 blades, but I do think both of those outperform the older, crustier MTV3s - especially ones with pretty little round blade tips on them. I have the 190 blades on all 3 of my 50s - I'm obviously biases. Plus, nothing looks better on a -50 than the 190 blades. . . .
so let it be written.

I did have the 190 prop and did like it, but I am back to my crusty old Mtv3 again. It was on *loan* to me and unfortunately the loaning party found a need for it. I was just helping keep it warm, I swear.
The Fw190 blade was great in the 50 because of the amazing braking action in the pattern. The Mtv3 climbs similar and maybe a little faster overall. But I am just not that good of a pilot to tell a huge difference. We are talking small differences here.
Fact is that my Yak 50 with 430hp and 1687lbs empty weight is a monster no matter what prop is on it. I just hang on and fly wing where I am told.
