Do not forget to install the rivet that holds the roll servo bracket on the torque tube - If it slips it can get to a position where it is directly in line with the servo arm and will jam full left with no chance of recovery from the roll.
The manual shows that rivet but it is easily overlooked - Be Aware.
I would recommend checking the position at least every 100 hours and possibly whenever you have a situation where you are forcing the stick in a roll against the force of the autopilot.
ps : when drilling that rivet hole be sure to use a drill stop.
