Hi all
I am building my first kit, a SIG Kadet LT-40 Afte building the left wing and taking it off the builind board I noticed that the ribs are not 100% flush with the trailing edge on the bottom

, they all stick out about 1/16th. Obviously they are then slightly sunken in on top. Would that cause any problems sanding them flush between the trailing edge and the bottom back spar? Would it affect flight charactistics? I am trying my best to get things 110% right, but that made me wonder how "inaccurate" a trainer can be built and still fly properly.
