Yes, I recommend centering all the servos and installing the servo arms prior to installing them. I always do it after so I do not have to fiddle with my transmitter while I still have sticky fingers and glue all over the bench. I'm building these things fast to get the build threads up before everyone gets theirs. If I had more time I would do it your way.
I haven't weighed the production model but it is 6.XX oz depending..
FYI - You can get a $6 servo & motor tester which allows you to test and center servos either in or out of the plane without a transmitter. It will test motors and esc's as well.
