Just to add, there are various M/R systems out there that balance out certain aerodynamic forces with its design similar to the 407 cyclic cam. For example, the R22 delta 3 M/R and swashplate design was partially influenced to reduce the lateral inputs required when the cyclic is moved forward. However, you need to be at the Ray Prouty level of understanding to see why the cyclic cam or delta 3 designs are needed. But from my experience there is a lot more going on upstairs when you push that cyclic forward.
