You're not facing any issues that the rest of us didn't face.

The biggest is that the full scale arrangement of thrust line, stability margin and wing and tail incidence is set up for a completely different balance than we would have on a scale model of the same plane. Due to the lighter weight and Reynolds number effects they share nothing at all in common other than the exterior shape. Often we won't even get the best performance by using the scale airfoil depending on the full size design.

Also in your first post you more or less hit the nail on the head as we sort of described along the way. Full sized pilots fly their planes in a far different manner than we do as modelers. For them the designed in safety factor demands a more forward CG and that comes with a negative load at the tail vs our models where there is often a neutral or even positive lift load at the tail thanks to our "tolerance" of more rearward CG's compared to most full sized airplanes.

Why the difference? Because full sized pilots work with the airplane more then most modelers are willing to do from the evidence of the threads here about "why does my plane nose up?". Full sized pilots use the throttle to control climb and the elevator and elevator trim to control speed. When was the last time you found a modeler that flew like that? Yeah, I thought so.... Full sized pilots fly that way because of the mandated in stability margin in all but the hot competition aerobatic ships. With that stability margin comes the need to work with the aircraft rather than just horse it around.

But even the scale model fliers won't tolerate or learn to use much of what the full sized pilots will. So we are back to rolling our own when it comes to the thrust, wing and tail setup on a scale model.

Does that help you settle the confict?
