Saitek Throttle Quadrant Spiking

Incredibly, last night, my Saitek throttle quadrant's throttle started to spike. Came into the local field, coasting to a stop on the tarmac, brought the throttle to idle and VROOM! Power up! Jiggled the throttle a bit and it calmed down, but not by much. Went into "Control Panel/Game Controllers", selected the yoke setup and "Properties" to check it out...sure enough: the throttle lever spikes throughout the range, most noticeably at idle, but this is also with the prop and mixture levers full up. The more I bring those two back, the less of a spike issue the throttle lever has. Interesting...I popped it apart (I've been prying open/cutting/soldering a lot lately!).Here's what you find when ya get inside:

Image 1 is the throttle lever assembly, including the trimpot. The arrangement is a modular, cartridge-style; The trimpot clips onto the module and is secured with low-temp hot-melt adhesive. A small tab on the throttle pivot axis engages a slot on the trimpot.Image 2 is the trimpot itself, which Saitek's tech rep refers to as a "mini VR". Same difference. The manufacturer cannot be identified, the only markings visible on it are "8", "5", "B" and "103". No manufacturer code, no YYWW manufacture date (e.g. 0628). Earlier in this thread, NeilC explains that only 90 degrees of its 270-degree operational range are used; however, there is no internal or external stop, so the pot has a full 360-degree physical rotational range, meaning there is, by assumption, a 90-degree 'dead zone'. The trimpot is responsible for both a variable operation (throttle, et al.) and an on/off operation when moved below the lever's detent (thrust reverser, et al.).NeilC also relays from his own tech that this trimpot is not easy to find, which is about right. Going to several sources, eBay included, yielded nothing of any ohm range in that type of package. The vast majority are PC-board-mount type. Only a few appear to be of a type utilising engagement by a tab, such as in this scenario. None of them are clip-on, as depicted in Image 3. This is, for all intents and purposes, a proprietary component.IMHO, I cannot agree entirely with the independent tech's opinion of "bag of sh1te", unless he refers solely to the trimpots; the design appears well-thought-out, it seems the only problem we have here is with the integrity of the trimpots. So, with this in mind: what do we do now?
