I usually have full up elevator as I taxi out and line up. As I give it throttle and the model picks up speed, I let up on the elevator and concentrate on the rudder to keep it tracking down the runway. Just a little up elevator is required for takeoff once it is up to speed.

It sounds more complicated than it really is. You are correct in that you can hold down the back end with the elevator when you start to give it throttle, there is no lift from the wing untill you get some speed and you can use the elevator to keep from nosing over.

The challenge is to not let the mains leave the ground until you have enough speed to fly.
