Default Setting Up Control Throws



My son and I attended an IMAC boot camp a few weeks ago and now he's moving from his Astro Hog to a Phoenix Models Extra 330. I'm setting up the plane for him and we were adjusting the control throws, end points, etc.. A question occurred to me which I haven't thought about before. When measuring the control surface deflection, what is the best way to assure that the throws are equal in each direction? Adjustment of the control horn and linkage or with the radio?Wee set up the linkages as identically as we could, but there will always be minute differences in the exact location of the servo mounting holes, the control horn holes, etc.. However, when we measured the actual deflection of the control surface, we found that one aileron would deflect 1/4" more in one direction andthe other 1/4" morein the other. By adjusting the individual endpoints back we were able to equalize the throws. So basically although the servos have different amounts of motion, the control surfaces such as the ailerons now deflect equally. Does this sound like the right way to do it?
Thanks in advance,
