I'm also building one right now. Not many of us building these things I guess because they don't make them anymore. The CA hinges will work fine on all the control surfaces. I'm also installing a O.S. 1.60 FX on mine. With a slimline pitts muffler and a perry vp-30 pump to help with the fuel problem when you use a pitts muffler. I'm going to use Hitec 945 on the rudder and 605's on the ailerons and 2 545's on the elevators. I'm going to mount 2 elevator servos in the factory spot on either side of the rudder servo and use carbon fiber push rods for each half of the elevator.
Keep me posted on how it goes.
