You can see that I biased the deflection from neutral to limit the amount of nose down force that I'd have to overcome in the case of a trim switch run-away in that direction. The 14=B0 may, in its self, be too much in that I've never come close to that position. My normal fast cruise (195 kts indicated) will have the indicato= r at the third dot. In a descent I've seen the indicator at the second dot. This gives me a descending speed of about 225 kts indicated. Quite frankly, I've never paid attention to the indicator to see what position its at when trimmed for landing. I don't think that I've ever com= e close to the 24=B0 maximum for nose up. I'll have to set up a slow speed cruise (the next time I do a gear down manually check) and look at the indicator. I'll do this sometime next week and let you know. Hope this helps. Hal
