No problem. Just remember you always have to activate a pitch curve in the throttle curve menu first. Also if you have I1 and I2 disabled then flipping the switch by accident wont do anything.

Dont forget to set up your throttle hold for a reliable idle, if something goes wrong try to flip the switch before you hit, less energy in the blades will do less damage and keep you from doing the chicken dance where it beats itself to death on the ground.
