That is exactly how I have done all of my planes for the past 6 years! Leave just a thread or two sticking out of the 2 or 2 1/4" horn screw and use the 1" from the center hole on the servo arm. That way you can use maximum ATV to get the finest movement in the trims and ATV on your transmitter. I think I said that right. Instead of having to use 60% on low rate this way you can use 80% to get the same throw!!
