Phew, I made it without a disconnect
I recall someone asking which servos I was going to use, so here it is: Hitec HS-425BB's on the ailerons and elevator, Hitec HS-525BB on rudder, and Tower TS-53 on the throttle. No particular reason for any of them other than I had them laying around. I did consciously put the faster servo on the rudder, though, since I want fast response from it.
Now I just have to set all the control throws and the CG. It looks like I need to add around 1 oz to the tail for the starting point. Any suggestions for a clean way to do this?
