I have an Arplast VP50 propeller. I have a problem with the pitch change system. When tested on the ground, I can run the pitch from full corse to full fine with no problems. I get normal operation for a 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?

As my Europa is on the British register, I will need to get approval for the change. Has anyone with a G reg Europa done this Mod? If so could you give me details? Thanks guys.

Top Quality, top service, although not quite cheap.

One of your statements that jumps off the page at me, is that you have no issues on ground tests, I assume from the way you've written it, that means before the flight - is that correct? And then after the flight has completed, the issue remains - again, is that the correct understanding? Do you have the Arplast standard VP controller installed?, or a CS controller (CSC-1 etc.)? If you have the Arplast controller, have you changed the batteries (sorry, obvious question :? ) If you have changed the batteries (or you have a CS controller installed), then I would recommend putting a new 9V battery directly across the motor power terminals. You can do this with just the spinner removed. This will directly test the motor itself. If the motor is supplying enough torque with the power attached directly to it, then it implies the wiring could be at fault. If it points to wiring then, from what you've written I would want to eliminate thermal effects. I suggest taking voltage measurements at the PV50 motor while the engine is cold and then again when the engine is hot. From what you said, it sounds like the problem is reproducible, so you should be able to collect some good fault finding data. If you do need a replacement motor, I know that Kevin Kenward was trying to establish a "support network" for the Arplast PV50, following the company's demise. You may have to check directly with him, but if I recall correctly the motors are "Commercial-of-the-shelf" from a company in Germany.
