I have been running 1 servo per wing on the 330 version with no problems so far. But as mentioned I used the stock clevis on the phenolic and a ball link on the servo arm. Going on 2+ years now. As long as you do not put a ball link on the phenolic you are fine. Nothing wrong with the stock set-up either, but I was using swb arms on some of the servos.
It's the plane in my avatar, nothing flies like a 22.5 lb comp arf.
