all 3 servos should be moving down when raising the throttle. On the V120 the links on the blade grips are on the trailing edge of the blades so the swash moves down to get positive pitch. When only moving the throttle the swash should stay nice and flat in every direction.

Is it only the single servo or all three pulling down when you apply throttle? As vultage said it's a trailing edge linkage system so the swash moves down to increase collective.
