Change the weight and look at the Power Pitch amounts. If you increase the weight, the Power Pitch increases automatically. So if you increase the weight, the pitch speed remains the same, but the overall feeling corresponds to the higher weight.
Why this? It's simple: When setting up a helicopter, you have a few parameters that you can measure on your real model. Maximum pitch angle, rpm, weight and the resulting climb speed. You can also measure the collective pitch angle for hovering. This should be adjusted with the Response Pitch setting in the sim. And then ... all you have to do is adjust the Pitch Brake Dynamics and you are ready.
Do you mean "Power Pitch" with 2 fields? Just trying it with T-Rex 7000X Dominator / Electric. Sliding Weight doesn't change the 'Power Pitch", it is 80 for both positive and negative. Should it change?
