Richard,
I can't quite make them out in the pics but, if those are new 5600 series Hitec servos, exercise them at least 20 minutes before commiting to flight. All the ones I've seen go bad do so in the first 10 minutes or so. If they make it that long they should be good to go. I know I'd hate to lose one of these on a maiden flight. A friend gave me the same warning when I installed four new ones on my old GP Giles. One aileron servo went hard over and stayed after about 10 minutes. He had experienced the same thing. I replaced it with another one and never had any trouble.
