Has anyone set up their RV in the Foreflight W&B calculator? I am trying to but got stuck. It calls for the user to come up with and enter multiple forward and aft CG limit points. Each such point is supposed to have its own unique weight. How do you pick the points and calculate the weights for those points? The Foreflight instructions say to pull it from a W&B graph. I did not receive a W&B graph with our RV-6A and am working from the original W&B. Thanks in advance for the guidance.
