Here is what Lego told me when comparing the 2 models. I knew his was more accurate ... makes sense. I guess I'll be hanging on his original version so that when/if I ever get my own I'll be ready!

Hi Dion,
Both versions you sent me are fun to fly! The second one is really extreme!

But compared to reality both react too much on pitch changes. As I said
at RCU, in reality if you change from full throttle forward to full
backward the plane just needs some seconds to follow. It does not stop
emediately, as your two variands do. It is more a soft transition from
forward to backward flight. And in between, while you are already at
full throttle backwards but the plane still moves forward (while
breaking, so to say) the model is allmost uncontrolable but is somehow
stabilized by the propeller moment. You will see, if you have tried a real
pps the first time. It does not follow your throttle input that accurate.

Greets,
