I only skimmed the responses here so maybe someone has already answered this but elevator does not really control "up" and "down"; it controls speed. So in that sense it moves the same as the throttle: stick forward to go faster, stick back to go slower. If you think about it, which way does the nose have to go to slow down and flair for landing? For a fixed throttle setting if you pull back on the elevator the plane may zoom up but you will start losing speed and eventually stall and the plane will fall out of the sky. To go faster and maintain constant altitude you have to push forward on the stick to gain speed and forward on the throttle to maintain altitude. So the arrangement is perfectly logical if you get away from misconception that the elevator controls up and down. I think R/C modelers miss this because we tend to fly at full throttle all the time and just use the elevator to zoom up and down to keep the plane in sight just like we only use alierons to turn.
