I dont run a VP prop but I recall from other posts that the electrical supply
through
the brushes is important and any high resistance due to poor contact or
wear on the brushes might have similar effects.

with the pitch change system. When tested on the ground, I can run the pitch

while
in flight, then the pitch change seems to stop working. When I test the prop
after shut down, the pitch change motor does not seem to have enough torque
to run from one limit to the other. The motor stalls after very little movement.
Any ideas what could be the problem? I have been careful to lubricate the
jack screw often, so I dont think that is the problem. Any idea where I could
get a new motor? And as a last resort (considering the demise of Arplast), what
propellers are approved for G registered Europas?
