So a correctly trimmed 2 pound electric park flyer will fly well in a 15 knot wind? I don't think so.
At first I read this and thought what an over exaggerated example it is. But I thought about it more and the answer is a yes! A well set up and trimmed 2 lb airplane would fly better then a poorly set up and trimmed 2.5 lb airplane in a 15 knot wind. Again, the airplane sees wind as a change in airspeed. A poorly setup airplane will react to changes in airspeed so obviously it will react to wind. <span style="color: #808000">Ask yourself if your airplane's trim changes at all between 1/4 and full throttle. If the answer is yes then it is not trimmed correctly.</span> Does it really matter? Not if you are happy with the overall performance.
Icannot fully agree with the green colored highlighted above.
Just before take off the trim is set for normal climb.
On levellng in cruise the trim is reset for cruise.
On descent and approach to landing again the trim is reset for approach speed.
None of the above apply to a model flier just constantly executing changes in attitude (note att no alt).
Changes in trim with changes in power setting is normal and not an indication of not being trimmed correctly.

Zor, for the most part you are correct. I am trying to keep the discussion in context. The airplane in question is a sport aerobatic airplane with a symmetrical airfoil and is fully capable of being trimmed to not have any pitch changes during most throttle settings. If we were talking about a trainer or maybe a warbird, the pitch change would be of benifit especially a trainer that would be set up to climb and self right in the event of a dive.
