I am at my wits end trying to figure out how to make my single, servo operated door not start closing until the electric retract has had time to retract into the fuselage.

This jet, Avanti XS, only has one door on the nosegear (no doors on the mains). I have the servo currently set to open at its full speed when the gear is going down and it is closing currently as slow as is possible (slowest setting in Servo Speed) but it still contacts the nosegear while it is retracting. I just need a delay so that the servo doesn't move for maybe 3 seconds after the retract switch is activated.

I'm hoping there is a simple way to accomplish this as I have a low aptitude for figuring out complex mixes.
