| Subject: | More of CE Baily's canopy glass |
This is the 52 eyebrow glass. The flat glass was cut so small it would not e
ven fit in the frame.
They would not stand behind their product since I bought the turtle deck and
slider glass two years previous. They said they would cut the windscreen ag
ain if I sent them my old glass as a template. I said how about I send them a
card board replica. Then I suggested that I just return them the whole mess
for a refund. They said they could not give refunds.
So deal with them at your own risk.

I just installed the 4th set of canopy glass.
I have used 3 different suppliers.
Doug Sapp turned me onto LP Aero Plastics and it is the best set I have
installed.
Less cutting and better fit.

| Subject: | YAK-50 Aft Lead Weight |
Question: Are there any YAK-50 owners out there that know about the lead weight
that was installed at the base of the vertical stab to make it snap better?
This was done in Russia back in the day, and I found it (and removed it) in my
50, and have since misplaced the weight. Anyone else have any detailed knowledge
of this?
Thanks,
Mark

I can remember members of the Russian team showing me the weight, but it was
many years ago and I could not be precise about its location or mounting!

Hello Yakkers,
My engine has developed a vibration when running my M14P at 80% & 8. It's almost
like a drone that comes in every 2 - 3 seconds. At every other power setting
it is fine. Has anyone else experienced this before? I have been in touch with
Jill who thinks it could be a bent link rod.
Cheers.

What is the balancing history of the prop? Both static and dynamic? I am
not an expert but to me a bent rod would show up at every power setting.
And to I've never had any experience with bent rods or what preludes their
failure. I know that when doing dynamic balance, it is done at specific
RPM, one the operator feel he will spend most time at.

Any drone of vibration felt in the cockpit, kinda like a twin engine
prop out of sync... is usually due to, say, an airframe problem... too
much slop in a trim tab.
Or to a prop problem.. like a blade angle getting out of sync..
My first guess is to check the blade counterweighs which may be a little
tight, due to needed lubrication.. or a slight difference in bolt torque
on those counterweights which may cause a sticking blade not to follow
the other..
One time, after shipment, a crew failed to turn in on blade that last
millimeter to bottom one blade.
When you search for someone to provide a dynamic prop balance, be sure
to find someone with lots of experience...
Its rather easy to do a Pratt 1340 which usually has a tight planetary
prop reduction system.
Most respond well and are predictable..
But M14 engines can be all over the place...
The frequency sidebands can confuse the balancing equipment easily.
I don=99t post here often... But Monty Barrett and Allen know
me..
Tulsa Oklahoma a number of Yaks & Cj=99s.. Not writing about me
but, Some Mechanics here are very good and know the models well.
regards.
