RE: Mix Elevator with Throttle for Scale Flight?
I teach people to fly with a slight amount of down trim..so they must maintain a small amount of "back stick" to maintain level flight. This gives the student the feeling that they are flying the plane 100% of the time, plus if they get unaware of an impending stall, they can release the stick and allow the plane to self correct instead of pushing the stick foraward into some sort of a "panic mode" reaction.
They are also taught at constant power settings [for similar reasons] until they have proven to have mastered the level of power that they were given.
Learn to fly with your thumbs and your eyes.. You can't "program" your way to competence like it is some sort of a video game.
