No not done any mods apart from hysoling a carbon outer on push rod and making hole bigger for the push rod. On my plane it certainly did not seem it needed putting the horn at the corrected angle etc you did not have to force to make the connection to servo arm. One thing I am doing though is to change my servo arms to metal from Dubro plastic

I was aware of this 'problem' but I found that it was not a problem on my Hawk also I used clevisis and not ball joints, if your using ball joints I would ensure that they are bolted ones and not 'press' on type

Edit: as Dave has posted I think there are some planes that need the horns cracking and some that do not, when I was installing the rods I was ready to do what Dave had suggested but just found it was not necessary.
