| Subject: | Aeroplast PV-50 issue |
I haven't investigated the source/cause yet, but all of the sudden (after
~200hrs) I had significant grease exiting around the root end of one of my
three prop blades (Aeroplast PV-50 in-flight adjustable). It dotted my
canopy a bit during the flight and after my flight there was a nice
accumulation on the leading edge of my cowl. I'll be checking it out later
this week, but would appreciate any input, if by description someone else
already knows what the issue is. While I'm on the topic, I'd also like to
hear from anyone using the same prop (I don't think there are many)
regarding what range of pitch you are using on a 912S and whether any of you
have used the constant speed controller.
Thanks,
Tim Rupp

Hi Tim,
I have been using the PV50 for around 13 years now and it has always
leaked grease. It seems to get less over time as the grease in the prop
disappears all over my canopy but it has never been a problem other than
the mess it makes.
I do use the constant speed controller (UK designed model) and it works
extremely well - I love it and would hate not to have it installed
anymore.
Mine is on a 912 and I have no idea of the pitch range in degrees - the
CS unit runs between 50 and 75% most of the time. If you leave the CS
unit in cruise (without the manifold pressure transducer) and close the
throttle, the pitch goes very fine and the aeroplane nearly stops dead
in the air - you can really dive very steeply and not build up speed!
Hope this helps a little.

Hi Tim,
I've been using the PV50 for 10 years. Performance is great, and the
only trouble I have had was a burned out pitch motor after about 200
hours. Arplast sold me a later version replacement which is working
fine.
I've had grease escaping since day one. I used to put a lot of grease in
the hub, but that is a waste of time because it just ends up on the
canopy and especially around the front of the cowling inlets - - and on
the front of the engine. More recently, at each annual, I dismantle the
hub and re-grease the thrust bearings and put a smear on the swashplate
and the sleeve bearings on each blade. I still get get grease thrown
around for a few flights afterwards, but it gradually becomes less.
There is still plenty of grease in the hub bearings each time I have
opened it.
I have the 912 also. No CS unit, but I modified the control unit so that
the pitch readout is in degrees of blade angle. I have a range from 18
to 30 degrees available. Did a lot of flight testing originally to
determine optimum settings. Normally I use 21.5 degrees for take-off
[but watch the rpm as you climb out], cruise at 5000 rpm and 25.6
degrees [or thereabouts] at 120 knots, and maximum speed at 5400 rpm is
at about 28 degrees.
Like Barry, I occasionally use a fine pitch setting if I want to slow
more quickly for landing - - as long as I know for sure that I am not
going to go around. Actually, for a go-around the normal take-off
setting of 21.5 is too fine, as you are already doing say 60 or 70
knots, so if that is likely to occur I need to be quick on resetting the
pitch or take care adding power to avoid over-reving the engine. [And as
you probably know, the Pulsar will climb out very well with less than
full power.]
Since yours is probably a later prop, I wonder if the O-ring seals have
been improved to lessen the grease escaping. Perhaps one blade seal is
now less effective.

You are all invited to the 2011 winter gathering of Pulsar pilots and
builders on Saturday, February 12 in the Houston area. If flying, plan your
trip to Pearland Regional Airport (LVJ) between Houston and Galveston. If
you don't want to talk to Houston approach, you can easily fly in under
Houston's Class B 2000 ft. floor.
Lunch (BBQ, what else!) will be at Jim & Rhonda's home, 248 Kettering Lane,
League City, TX 77573. Transportation from/to the airport will be provided.
I have it on good faith that lifetime builder Tom Gibbons from Lake Elmo, MN
will be in attendance. Please let us know if you'll join us.

Thanks Brian & Barry for you input.
I don't have the earliest history on the prop as Dan had already flown the
first ~60 hrs before I purchased his plane. From the time I started flying
it, there really has been no grease leak at all. I've never opened up the
hub itself, so the only "maintenance" that I've done is assuring the lead
screw is greased and I've also replaced the batteries in the control unit.
As easy as it is to adjust the prop (thumb switch on the stick) the only
reason I have considered the constant speed module is specifically so I
don't have to watch the tach like a hawk when I'm climbing out aggressively.
A slight distraction and very subtle drop of the nose will let the rpm get
away quickly! My display has not been calibrated to read actual degrees,
but I use a spread of just over 9 degrees between take-off and cruise
settings.
After my original post, I realized I mis-typed the name (Arplast) and that
there are several blade combinations used so pitch info is going to be
relative based on the blades used. As far as I know there isn't a US
distributor now, but if there is, let me know.
Thanks,
Tim Rupp

Tim,
I have only dealt direct with the manufacturer in France, and there is
no agent here in NZ either. The guy I have spoken with, Alain Petit, can
speak a little English and I can understand a little French, so with a
little difficulty we have sorted out any issues. He does respond in
reasonable English to e-mails.
Making some small changes in the control unit to calibrate the display
in degrees is not difficult. I'll send you a copy if you wish. I note
that a later control unit, using an inverter instead of batteries is
calibrated to read out in degrees. I find it helps to understand where
the prop is.
