As I have said before, this a matter of preference, not a matter of right and wrong. I was always set up with push for fast, like a full scale aircraft. I suggest that you pick up a handle, and without thinking about it, tell yourself to go to full throttle. You will instinctively go one way or the other. Whatever you do, keep doing it that way. You want it to be automatic, not something you have to think about. The system can be properly rigged to work in either direction. With 2.4, pull for fast seems correct, perhaps due to the physical similarity to slot cars controllers and drills. Not to mention, most transmitters have direction-reversing switches.
