Auto Pilot Installation
You can install the AP brackets and the servos after the fuselage is done, as long as the fuel tank isn't in the way....its darn awkward, but do-able if you can still wiggle and twist yourself into the baggage area...I did it but would MUCH prefer to do it while constructing the fuselage...the servo itself for the roll would not be a great challenge but the brackets were the real pain installing them after the fuselage was finished. If I had to do it again I would work out of sequence until I had the brackets and the servos in hand.
