Subject: | Re: Arplast Propeller problems |
I had a problem with my PV-50 Propeller and CSC-1 Controller yesterday, and whilst
researching it on the forum, came across the posts below, which are the nearest
to the problem I experienced. My Europa has approx 60 hours on the Prop,
but the Prop was purchased many years ago (don't know the exact date but judging
from the documentation probably not long after 2000). It has been performing
as expected since installation.
After take-off, and switching from TKO to CLM Mode, I noticed that the engine RPM
remained near maximum, and looking at the reading on the CSC-1, it was displaying
40%. I tried changing to MAN mode but couldn't increase or decrease the
Pitch. I throttled back to reduce the RPM, but this impeded my ability to climb.
As it was a short flight, and I could maintain height, albeit at a slower
speed than I normally fly, I continued at low level to my destination. Once I
landed, (and at reduced RPM i.e 2500) the Pitch Controller functioned again through
the full range.
90 minutes later the Prop and Controller functioned through the full range in my
pre-flight checks, but exactly the same thing happened following climb out,
and all the way back home. I did notice a small change in the CSC-1 Pitch readout
the closer I got to home, but can't recall if this was as I throttled back
in the approach. Back on terra firma, the Prop again functioned through the full
range.
So it would seem the Pitch will alter at pre-flight RPM (2500-400), but not at
5000+
I didn't have time on my return to inspect the electric motor assembly, but plan
to do this in the next day or so. Apart from cleaning and re-greasing the worm
assembly, and checking again the full range of movement, has anyone any further
suggestions, or potential explanations as to why this could happen ?

My first thought would be to check the Brushes for wear, cracks, length and broken
wires.

Hi Mike,
I have a whole landing gear assembly, that I bought many years ago from
a U.S. builder, who was converting to a tri-gear .
Get in touch, if you are really stuck. Shipping would probably be
expensive, as I am located North of Vancouver, B.C. Canada.
My Europa is still for sale and can be viewed on my blogsite: Peter
Timm. blogspot. ca
Regards
Peter Timm

Hi
This is hearsay as I have never owned an Arplast but know a couple
people who have.
I seem to remember that there can be a problem with corrosion at the end
of the long rod contact that runs though the centre of the hub to the
propeller.
Good luck.

I have a Arplast VP50 inflight adjustable. I had the same problem. I changes batteries.
Checked voltages, etc. In the end I had to replace the motor and the
gearbox. Once replaced no problem.
The operation manual says not to operate without the engine running. The motor
is not designed to operate without the airloads on the propeller "The propeller
is designed to work whilst running. If the pitch is regularly changed whilst
the propeller is
stationary undue stress will be placed on the electrical and mechanical control
systems. We do not
recommend the propeller is run from limit to limit unnecessarily as this shortens
the motor life e.g.
before flight. DO NOT CYCLE TO PRE-FLIGHT TEST"
