If you're using pneumatic landing gear, then you have to slow the rate that the air passes through the lines. There are restrictors for that. Check with the maker of your model's landing gear.
yes .. i know the servo speeds are set at factory
some digital servos even allow u to set the speed according to your liking via some PC intereface
and of coz .. the easiest way is to do it via the radio .. the 12FG/Z and 14MZ has the speed control feature that was not incorporated into the 8FG
