There was no " push down or push up".
You got that right. And not in RC either.
Ever heard anyone yell,
"PULL UP! PULL UP!" ???? OK, with your TX in your hands, pull up. What did you do? You pulled the stick. And which way did it go.
In a couple of the different disciplines within RC there is considerable discussion of stick movement. Matter of fact, there is a fair amount of stick movement in full scale precision aerobatics. And when all those guys talk about maneuvers that require pitch up or pitch down they say "push" when they're talking about pitching the nose down and "pull" when talking about pitching the nose up. Wanna use the right words and be understood? Learn 'em and use 'em the way all before you did.
How in the the hell does it help a newbee like me,
Lighten up my buddy. The issue isn't exactly life and death and really doesn't need that kind of emphasis if that's what it was meant to do.
Am I the only one to do this?
No. But everyone else made a lot less noise about it.

Wait until somebody mentions your airplane's "water line".
