Hey Guys,
I just bought a Yak 55 M that has a MT 3 prop on it. Thinking about a MT9 or Whirlwind.
Thoughts?
Jay

Whatever the other qualities of the two manufacturers might be, a critically
important issue as far as I am concerned is that MT propellers are fully
certificated. This means that they have to go through a rigorous testing
schedule, involving a very significant overspeed for quite a long time. I
say this with some feeling, having had propeller failure (with another
manufacturer of variable-pitch propellers) in which a counterweight came off
and removed half of one blade. I would not wish this on anyone, and very
fortunately I was overhead an airfield practising aerobatics and was able to
land quickly. But various instruments were broken, and the vibration quite
incredible.

Hi Jay,
I have been flying the Whirlwind 3 Bladed Prop since 1999 and upgraded to
their latest model (all composite) in 2014. I fly a lot of formation and
Acro as much as the CJ can take.
They may have had some issues in the past but none for years and I had Zero
issues and actually, I Love this prop - not only it looks great, it performs
amazingly well. There are quite a few flying in the U.S, you might want to
take a hop with a Whirlwind and you'll see what I am talking about.
If you'd like more details, call me off list.
Not sure if you saw my youtube Product Evaluation video I made a couple
years ago about this prop but if not, here is the link to it:

If you are based in the U.S, I recommend, hands down, that you seriously
consider the Whirlwind... They are based in Ohio and have a great customer
service.

checked timing, left mag was 2.5C BTDC the RH 3.5C BTDC! They are 24 mags.
Yikes
I think you have probably pointed the finger at the most likely explanation of
the CHT drop.
Cheers

The numbers you have given for the ignition angle are not correct.
They are also corrupted by what appears to be a computer glitch. I am
referring to the "A(with an accent above) and the C with degree mark. I
note the A is also repeated in "they are 24 deg. mags." but not the C.
If the "C" is not an error I would interpret that to mean the angles you
have given are relative to the crankshaft. If that is the case they are so
far out I doubt the engine would run. If that is an error and you are
referring to the propellor shaft angle they are still far out of tolerance.
Please advise.
Rather than give you the numbers from memory I will confirm at the hangar
tomorrow and get back to you.
Walt
