RE: 4*120 Build Thread
It shouldn't be a problem. It will just be more work to handle the entire wing while you install the servo mounts.
I got one servo mount finished. I just took a piece of the lite-ply from one of the lightening holes in the kit and glued it between 2 ribs. Couple pieces of tri-stock underneath, and I was ready to hack the hole for my servo.
I'm using JR4721 coreless on the ailerons.
I'll post pics tomorrow
