Yes, that is exactly what I understood, and I'm as keen as you are to have a more
effective propeller to use with our up rated Huosai engines. The practicality
is that the Wilga propeller will fit straight onto the HS-6 propeller shaft,
since the AI 14 engine has the same shaft as the HS-6, together with, I suspect
more effective blades than the original Chinese ones. Also I believe that
the aerofoil section of the Wilga propeller is almost identical to that of the
V-530 propeller as used on the different Yaks, since they were designed at very
much the same time. Richard.

Sorry Richard, my message was not to talk about the hub you are using but to know
if the blades of a Yak 52 hub or any other M14 hub could be adapted on a Nanchang
hub.
As Marcell from Aerometal had told me that he used a hub from a PZL Wilga, I wondered
if we could mount the bolt / bearing from a hub of Yak 52 on the hub of
Nanchang and therefore use blades from Yak 52 or others like Whirlwind.

And for you, with your 375hp engine I am using, Yak 52 or Wilga blades are better
for general performances than OEM Nanchang blades?

Hello Jacques I wish I could be sure, but I've never been involved in any kind
of back-to-back test. But simply looking at the blades, the Wilga prop does seem
to be almost identical to the Yak V-530, and that prop is fine to transmit
to around 380 hp. Richard.

Another very cost effective solution would be to discuss the possibility of making
the Whirlwind W530 carbon fiber scimitar blades with the more coarse threaded
Nanchang/Housai blade threads. Plus there is such a huge market all over
the world for replacement blades even for the stock 285 HP Housai.
And now with much higher horsepower Housai engines Richard/Aerometal is producing,
what a benefit this would be to the entire global CJ6/Housai market.

Dennis,
I havr already asked Whirlwind and the answer was no (too much work).
Maybe if you US guys ask...

Mark,
I am installing a M-14p engine that the tach drive had previously been removed
then put back without properly engaging the air distributor gear. Is it possible
to re-engage the air distributor gear with the tach drive gear without removing
the accessory case? If so, can you share your experience on how to do that?
Thanks in advance,
Robin Hou
[quote="mark.bitterlich(at)navy.m"]Yes Doc, and that is what I was trying to emphasize.
Tell me exactly
which one of those spline cogs is attached to the Tach Drive! It's
important to know. The Tach Drive is not stand-alone, it is part of an
overall gear mechanism as your picture shows clearly. It does not
matter where the actual hole is on the case, what is important for the
average engine owner to understand is that the Tach Drive is part of the
whole accessory drive MECHANISM, and is a CRITICAL cog.
If you pull the Tach Drive Cover Plate clear out of the engine, you can
easily cause the Air Start Distributor to come out of time. This has
actually happened when some folks converted their Tach Drive systems
over to the P-1000 Tach by Horizon Instruments, that uses the Mag P-Lead
wire to determine engine RPM. They first pulled the Tach Drive itself
out, and then they decided to pull the next cover plate off in order to
make a blank off plate. Well, they went a tad bit too far in the "pull
and remove" phase, and managed to yank out the gear that goes with into
that mechanism you have a picture of, which allowed everything to come
out of time.
Give it a try and see what happens. :-) I would rather not. I saw it
happen after the fact, and had to re-time the Air Start Distributor for
the gent, which some folks claim is easy. I guess I am not as good as
they are, because for me it was a real task.
I am not an M-14 engine expert. Most of what I have learned has been
due to the mistakes made by myself and others. Some of those mistakes
have ruined entire engines, luckily not by me for the Grace of God! I
usually pass those lessons on via the Yak List. This is one of those
times.
Take care,
Mark
