More specifically, I was watching a video of an RC helicopter doing amazing stunts and thought to myself imagine being in a full sized helicopter doing that. I’d be dead! But then began pondering, would I experience the same stress on my body if I were smaller?
Perhaps an even easier way to distill this question down is, whatever amount of gforce we perish at, would that number be different if we were a tenth of our size? And what would be the main contributing factor? Our weight crushing ourselves? Blood not being able to flow? Fluids being pressed through our cells?

Some good points already, but perhaps most importantly for the initial question, when you are “scaling” the helicopter, you are also scaling speed and acceleration: The actual g-forces present in the spinning helicopter are not that large. It moves at a high velocity relative to its size, but absolutely speaking, it’s still quite slow.
So, even aside from possible size benefits for withstanding acceleration, helicopter small -> speed small -> gforce small. The fair comparison would be to have the tiny version of you in the large helicopter doing similar spins.
