> The most annoying part was that I couldn't have throttle on a completely separate control from the rotation axes

You wouldn't want that because throttle is essential for flight control unlike with fixed wing where it's somewhat set and forget in many situations. It's partially alleviated by 'real' radios not having a spring on the throttle axis, so it stays in the position you've put it and part of it is just more practice..

I was actually thinking more in terms of helicopters having the collective on a separate input from yaw... bur then again, helicopter pilots use their feet to yaw, not their fingers.

Not springing back the throttle to neutral makes a lot of sense and would probably help!
