VTOL Servo speed control

[tohclin]

I uses a linear servo for my VTOL project, servo 4. Since the linear servo is slow, I need to control the servo speed.
The linear servo moves from profile2(2000us) to mixer transition mode(1500us), then to profile1(1000us) slowly as I wish.
But it moves from profile 1 to transition mode instantly, then to profile 2 slowly. I am not sure if this is a bug or not.
