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.

---From the documentation probably not long after 2000). It has been performing
as expected since installation.

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.

in the approach. Back on terra firma, the Prop again functioned through the
full range.

further suggestions, or potential explanations as to why this could happen ?
