Cor, that brings back memories! Used to fly with Grumman AA1's, trim for airspeed, control height with throttle. Models do exactly the same, only not being in the cockpit with the numbers right there in front you need visual clues, so what looks like is happening often isn't, hence all the usual misconceptions about what things do. Trying to illustrate things with words usually only makes things foggier, but that last post, I could see it all again, line it up, check the drift, watch the hens teeth and real gentle with the throttle. Thanks.
Evan.
