You don't seem to be letting it get to you and that's great. I did exactly the same thing one day. I'd charged my plane and radio up at work one day in a corner. The boys in the shop at some point or another had fooled with my trims. I didn't notice either on my preflight, the deflection that you get with max trims is so slight. My Arrow seemed to need an awful lot of correction on the take off roll....but I live in Saskatchewan....wind is wind. I got the plane in the air and it was as unmanagable as one could imagine. I made one circuit of the pattern and brought it down safely, although exceptionally long, about 200 feet off the end of the runway. I was miffed as to what had happened as I'd flown a few days before with no issues whatsoever. As soon as the plane stopped I glanced down at my hands and thats when I saw my trim tabs all cranked over just as yours were. I'd practiced flying with tabs all cranked on the simulator a bit so it wasn't an unmanagable surprise. You won't do it again....but if it happens, next time you'll take a breath and fly it back in before anything happens....or just adjust your tabs AFTER you get to altitude...
