By all accounts, it is a parameter that controls the way the heli stops from performing a maneuver when the sticks are released. The higher it is, the more aggressive the stop. Too high and it may cause instability or bounce, too low and you'll get mushy stops. A value of 10 appears to be optimal for the ZYX V3.50 firmware.
