Default Vertical Power Reliability

I just had a failure of my Vertical Power VPX-Pro, the elevator trim limits no longer function, nor does the stuck switch feature. It will be going back after we complete our planned trip.
I would like to ascertain the reliability of the VP system now that we have a significant number in the field. Note:

Note:The poll questions are exclusive! If you have NOT had a failure then please respond with Installed XXX

I had a similar issue with an early VP-X Sport unit. The power supply that provides the reference voltage for the trim position failed to put out +5V. Sent it back and they fixed it. Ended up having some other issues with that unit, so I was given a replacement, which has been working just fine for 300 hours.

Mine is showing the position on the display and the trim position on the configurator is indicating movement etc. It just won't stop at the preset end points.

I'm old school and don't know if I'm eligible because I bought one of the very first VP-50s and it's been rock solid.

I kind of wish I'd bought two, though because when that one goes, I'm kinda screwed.

I have installed half a dozen VP-200's, a VP-100, several VP-50's and now a couple of VP-X's. Very few failures so far.

Jesse,
If you have the data, please post it for the survey. So far it's not looking to good for reliability!

I have a VP-200 that I purchased years before I flew. So far so good, but like Bob and his VP-50, if any of the components tanks (and with the 200 there's 3 main units -- control unit, display, and switch panel) then I'm hosed.

I stopped by the VP booth at OSH and had a brief conversation with Chad about a future replacement, but I'm still undecided on what direction to go when my VP-200 fails (and I'm 100% certain it will eventually). One things for certain is I won't go VP-X like as I don't like relying on my EFIS displays for power control--same reason I don't like and don't use my EFIS's built-in autopilot (my AP is a separate unit.)

I'll try to remember the stats. I don't think I ever had any failures of any kind on the VP-50's (2-4 installed IIRC) or he VP-100 (1 installed). I had some early issues with the VP-200's that Marc fixed, but it was fairly minor stuff. I have had one DIsplay Unit fail completely that I was able to find a new replacement for. I think I installed 4-6 of these units. I haven't had any problems to date with the VP-X.

The automatic mode switching was the best feature of the VP-200. Any of the VP-X compatible vendors could write software for automatic mode switching with the VP-X if they wanted to. I wish one of them would. That was such a great feature.
