Maybe the gyro just causes them to move much more frequently than Joe User does when he wiggles the sticks, such that the "active cycle" is too high to allow the components to remain cool ? I know that I lost two sets of 3421's that way, David Reid and one of his buddies also lost two servos apiece, and Harley Condra's 3421's melted their way out of their cases if I remember correctly.
