I have a lanier extra 330s 30% w/ 87 inch ws. I did not build this kit, but the guy that did build it tried to go from two servos in the wings to one. Being fairly new to the hobby myself (9months) I didnt check his work, and needless to say the first time i flew it, i found out just how poor the job was done. The aileron fell off in midflight, and thank god i wanst flying it, but the guy who was, was able to land it with one aileron and no damage. Anyway, my question is this, I am going back to 2 servos in the wings and I need to know if the hardware that goes into the aileron hard point must be perfectly centered or perfectly even with the outside edge of the servo. Even with the servo, I am about 1/3 instead of 1/2 of center. any advise will help, thanks, Cliff
