Well, the good news is that once I change out the pitch trim relay in Louise's RV-6, I should never have to deal with the older "dash 1" RAC trim relays ago - I'll have everything up to "dash 2" (the larger, newer) relays in both airplanes.
For those not familiar, the earlier relays have a tendency to start getting sticky, and fail so that you get no function in one direction. Generally, if you blip them the other way, you can then get it to work the way you want. My past experience has been that you have some time to change it before it quits completely, but this time, Louise had one problem a couple weeks ago, and this morning, it was pretty much dead - made for an interesting morning commute...
My advice for anyone that has the "dash 1' relays and still has access to them if you're building - change them now....unless you like having stuck trim in flight...
