Because the doors are only open at take-off and landing I would add a pre-process so the cover only appears when the landing gear keyframe is between say 50 and 200.

It would be up to you what code to use but you could use c_gear then add the two keyframe numbers into the two boxes, and pick inrange (or one of those will work I can't remember if I definately use that one).

I hope this helps?

Hi
First up yes you can do it,if its for fs8/fs9
What you need is a spare animation in fsds maybe water rudder deploy or concord nose up down,
if you use water rudder you need to add a contact point like this to the aircraft.cfg to get it to work
point.10=5, 0.0, 0.0, 0.0, 0, 0, 0.0, 0.0, 0.0, 0.0, 0.00, 3.00, 0.05, 0, 0.0, 0.0
Add some preprocess and condition as HABU suggested,then knock up and xml gauge so that the water rudder /concord nose  work only when in a certain speed frame ect,I cant really help with the syntax for the gauge as Im still a noob in that area
Cheers
