Apple scripts in FaceTime

Hi There, Not sure i'm hundred percent in the right section but here it goes.

I have started an apple script which opens facetime, calls a specific person and even makes the accoun i'm calling from fullscreen. The first problem is where i add the next keystroke line in it doesnt make the screen landscape. (which i would like). To further refine this i would also like the recieving account to go fullscreen and landscape by default. If anyone could help with this or can think of a semi decent workaround that would be amazing!

Thanks
