The TCW Trim Controller works like a champ.  When I first tested it, I thought there was a problem since it would only run for about three seconds and then stop.  But then I remembered that there is a “trim runaway” protection feature which prevents a stuck switch from resulting in the trim being run all the way.  So you just have to re-activate the switch if you ever need more trim.  There’s also a reverse trim function that also works perfectly.

There is also a high and low speed trim function so that when you’re flying slow (like in the pattern) the trim motor runs at a higher speed than it does when you’re flying fast.  I haven’t tested that function yet.

I also powered up the landing lights.
