RE: 3/4A PROFILE !!!
Dang combat you don't mess around at all!!! IMO if you want to use hs-55's on the rud/ele you should give your control surfaces pretty good size "counter balances" so the loads on the servos would not be to much for them. If you plan on going with out counter balances you may want to consider hs-65's or at least hs-56 karbonite geared servos on the rud/ele. I'm sure that if you stay below 16oz hs-55's will do the job on the ailerons provided you use one on each wing half.
I bring this up because I noticed the rudder does not look like it's gonna have a counter balance. Have you put a Norvel .074 on the Thrust-o-meter? I wonder what kind of thrust that little sucker puts out.
I love it already! Sweet looking little profile.
What is the wing span?
