Adjusting Servo Speeds

Hi everyone,
Just a quick question, is it possible to slow down a servo with mission planner??
Sorry, probably a dumb question!!!

Cheers

slow down when?
as a control surface? or some other function.

Its for quadcopter retractable landing gear. I’m planning on using a 25kg servo from hobbyking, however I need it to be slowed down so that it takes about 4+ seconds to transition. I will be using a flip switch on my transmitter to control it.
BTW - thanks for replying. Your mission planner is amazing!!!

I would suggest asking on the arducopter forum, I’m not aware of any method to slow it down.
